Valášková V., de Boer W., Gunnewiek P. J. K., Pospíšek M., Baldrian P. (2009). Meanwhile, most of the Planococcus bacteria have showed the ability to withstand heavy metals, produce surfactants and adapt to cold and/or saline environments [12–14]. Micrococcus, Gram stain. Colony morphology for these organisms vary depending upon the type of media on which they are cultivated. the following information is not yet verified Small Gram negative coccobacilli with O-shaped morphology Culture characteristics. Arb. I sampled two places, a piece of wood from my fire wood stack (which is exposed to the extreme cold temperatures of Alaskan winters) and the ashes from my stove. Bacteria Bacillus megaterium, Enterobacter gergoviae and Planococcus citreus can describe histidin as histamin. The results did not meet these thresholds, and this is the reason that the BaseSpace indentified taxanomy of Lysinibacillus sphaericus was rejected. It was identified in 1894, and was only approved in 19806. This app provided sample information such as the total number of reads that were used for classification and the percent of reads that were classified. A Gram-staining-positive and aerobic coccus with the ability to degrade petroleum bacterium, designated Y42T, was isolated from the Lenghu oil field located in the northern margin of the Qaidam Basin. Abstract. Gram Positive Bacteria. The gram-stain revealed that the isolate was a gram-positive coccid: Image 2. Once identified, I could then research the species and compare it’s physiology and genomic data to current literature to confirm the taxonomic assignment. 1. A hallmark of the genus Planococcus is that they are usually halo-tolerant gram-positive bacteria that frequently inhabit Antartica4. The gram stain was performed to assess the thickness of the peptidoglycan wall. Pigments may be produced by some species; ranging from cream, pale yellow to light pink. One representative of each from gram stain positive and gram stain negative bacteria was selected to further assess the MIC. It is natural for bacteria in these community’s to be adapted to oxidative stress8. The sample was stained using the provided protocol, gram-positives and negative controls were compared to the isolate to determine its gram-state (lab 4). Bakt. Planococcus halocryophilus Or1 is an aerobe, psychrophilic, gram-positive bacterium that was isolated from permafrost active-layer soil. One such mechanism is the use of Catalase to catalyze the transformation of the reactive species hydrogen peroxide into O2. Decomposing communities frequently have a mix of fungi and bacteria. The DNA was then sent to the UAF’s DNA Core Lab sequenced using the Illumina MiSeq DNA sequencer which utilized the next-generation sequencing methodology. Euzeby, J. P., & Parte, A. C. (2017, April 1). BLAST classified the organism as Planoccus donghaensis with a query cover of 77% and a 78% identity. The API 20e tests had negative results for all for the 21 tests: Image 3. These tests proved that the microbe could thrive in an oxygenated as well as an anoxic environment, that it contained cytochrome c oxidase which is a part of the electron transport chain found in microbes that utilize oxygen, and that it contained the catalase mechanism for dealing with oxidative damage, respectively. The contig.fasta file from the SPAdes Genome Assembly produced by Illumina’s BaseSpace was analyzed by BLAST. compare with Marinococcus, Migula W. (1894) Uber Micrococcus kristinae 4. To control growth rates the plates were grown in incubators for 2-4 days at 37 degrees Celsius then moved to a refrigerator to ensure colonies did not grow large enough to touch. Micrococcus agilis 2. Planococcus sp. The gram-stain revealed that the isolate was a gram-positive coccid: Image 2. Several other species had similar query cover, including Planococcus antarticus: Image 7. Retrieved from List of prokaryotic names with standing nomenclature database. The isolates holotolerance was not tested but the similar cellular membrane composition and habitat conditions indicate that this genus is likely correct. BaseSpace has many apps that provide different information about the genomic data. PAMC21323 are shown in Table 1. Both sources have specific classification percentages that confer certainty. Stomatococcus The sample was streaked using the quadratic method to grow pure isolated colonies onto a tryptic soy agar (TSA) plate. Genus planococcus. At this time the culture was transferred into an agar slant. The results of the SPAdes Genome Assembler were above required values; # contigs >=1000 bp should be in the hundreds, total length should be at least a million bp and the longest contig should be at least 100000 bp. P. donghaensis may have had the ability to deal with these temperatures in its genome, but it is not certain since it’s environment doesn’t select for such characteristics. The final app Prokka Genome Annotation assigned gene regions that likely code for either tRNAs, rRNAs, CRISPRs and coding genes (CDs) and the abundance of them. The microbe was susceptible to all eight antibiotics tested. Dna was extracted and purified from the isolates cells using protocol from lab 5. Cells of strain AJ003T were aerobic, Gram-stain-positive, cocci-shaped and orange. The next app that was used was the Kraken Metagenomics, which provided taxonomic assignment. The thioglycolate test had growth throughout the agar with thicker growth at the surface, which revealed that the microbe’s oxygen class was facultative aerobe. Your email address will not be published. Considering the limit of species identified to this date, there is the potential that this microbe could be a new species. By Ethan Hanson Classification: Kingdom: Bacteria Phylum: Firmicutes Class: Bacilli Order: Bacillaes Family:Planococcaceae Genus: Planococcus Species: Planococcus halocryophilus Planococcus halocryophilus is an aerobic, gram-positive bacterium that is found in arctic permafrost. (2016). P. antarticus thrived in an Antarctica, my sample would likely have similar mechanisms for surviving temperatures around -45 degrees Celsius in Faribanks winters. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. nov. M. Engelhardt , K. Daly , R. Swannell , I. The cell walls of Gram positive bacteria differ structurally from the cell … After a two-day waiting period while the microbe was given the opportunity to develop where it could, the diameter of prohibited growth was measured and compared to standard antibiotic specific diameters and then classified as either susceptible, intermediate or resistant. Halotolerant will grow in nutrient agar 1 micrometer diameter, coccus, cells divide linearly. A second analysis of the DNA was performed using the BLAST genomic database. Planococcaceae, a family within the order Bacillales, embraces 14 genera: Bhargavaea, Caryophanon, Chryseomicrobium, Filibacter, Jeotgalibacillus, Kurthia, Paenisporosarcina, Planococcus, Planomicrobium, Rummeliibacillus, Solibacillus, Sporosarcina, Ureibacillus, and Viridibacillus.Members of the family are Gram-variable, spore forming or nonspore forming, and motile … Gram‐positive to Gram‐variable. , while the 5. Planococcus. If any microbes grew from the firewood it would mean that they were able to withstand temperatures below -50 degrees Celsius and be psycrophiles, if any microbes grew in my wood stove they would have had to be thermophiles. Image 6 To 20 Classification Results by Taxonomic Level from BaseSpace. Planomicrobium okeanokoites was reclassified from Flavobacterium okeanokoites. coccus-shaped gram-positive Fackrell, H. (n.d.). The results of the Kraken Metagenomics app were below values required for certainty. Tests were performed on the isolate by obtaining cells from either the TSA plates or from the slant agar. Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, coccus, tetrad-arranging, pigmented, saprotrophic bacterium that belongs to the family Micrococcaceae. The Prokka Genome Annotation app identified 64 tRNAs, 0 rRNAs, 1 CRISPR, and 3739 CDS. Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia.It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest.It is associated with citrus, but it attacks a … masc. The antibiotics tested were Amikacin, Cefazolin, Cefoperazone, Gentamicin, Piperacillin, Tobramycin, Trimethoprim and Vancomycin. The susceptibility of the isolate to 8 different antibiotics was tested using the Kirby-Bauer Method agar and the disk diffusion test per the protocol of Lab 9. haemolysans, Lactococcus Leuconostoc, Based on multiple To thrive in this community it would be helpful to have mechanisms to process radical oxygen species. The Microbes transfer to the agar slant was successful: Image 1, and was successfully re-cultured from the slant when necessary. A series of patented solutions C1-4 were added following the protocol to purify and remove inhibitors and proteins until all that remained was a pure solution of DNA. Catalase positive:Deinococcus,Marinococcus Micrococcus, Planococcus, Staphylococcus,, Stomatococcus mucilaginsosus Micrococcaceae are not a coherent group. Gemella Karlsruhe 1:235-238, p 1781 Genera related The isolate was found to be susceptible to all antibiotics tested with the disk diffusion test. Considering that the API 20e test is designed for enteric gram negative microbes these results are confirmation that the microbe is gram-positive. Of the few documents that relate to Planococcus donhaensis, there is one that notes the origin of the sample, the South Korean Sea. Stomatococcus Micrococcus luteus 5. While under the microscope it was observed that the cells could be aligned linearly, in pairs or quads but not in a longer strep chain. to the Genus. The species classification with the highest query cover is poorly documented in literature. While the cells were prepped in slides some characteristics were observed with the microscope, such as cell alignment shape and length. pluton, Pediococcus, Saccharococcus thermophilus, Staphylococcus, The first publication of a species under the genus Planococcus was P. citreus. A suspension of the microbe in broth was tested simultaneously in all 21 of the tests included in the API 20E test strip. The bacterium was found to be aerobic and Gram-stain positive. mucilaginsosus. but poor growth less than 1% or more than 15% NaCl Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacillus, Planococcus antarcticus CMS 26or is a mesophilic, gram-positive, motile bacterium that forms circular colonies and was isolated from cyanobacterial mat sample. Colony morphology on the TSA agar revealed a yellow colony that’s size increased with time, a smooth round margin and the colony was an elevated domed. Bacterium Planococcus halocryophilus that is able to thrive at minus 15 degrees Celsius offers clues about microbial life on both Mars and Enceladus. These communities emit extracellular enzymes to decay the wood, this results in an environment with high acidity and enzymes that are producing free radical oxygen species7. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. Plesiomonas shigelloides The sample was collected from a dry piece of wood. have atypical Gram positive cell walls. 16S rRNA gene sequence similarity of strain SCU63 T to species in the genera Planococcus and Planomicrobium ranged from 96.5 to 98.6 %. Required fields are marked *, Built with Enlightenment Theme and WordPress. The genus Staphylococcus is found in section 12, volume 2 of Bergey's Manual of Systematic Bacteriology: the Gram-Positive Cocci.The section includes aerobic genera (Micrococcus, Planococcus and Deinococcus), facultatively anaerobic genera (Staphylococcus, Stomatococcus, Streptococcus, Leuconostoc, Pediococcus, Aerococcus and Gemella) and anaerobic genera (Peptococcus, … Firmicutes / “Bacilli” / Bacillales / Planococcaceae / Planococcus Cells coccoid , 1.0–1.2 µm in diameter, occurring singly, in pairs, in groups of three, or as tetrads or clumps of cells. Table 2: Antibiotic Susceptibility Results. ein neues System der Bakterien. The multiple sequence alignments of 16S rRNA and housekeeping genes showed that … The SPAdes Genome Assembler provided the overall result of the genomes assembly. Of this information, only the number of contigs that were greater than 1000 base pairs long [# contigs (>=1000bp)], The total length of the assembled genome, the longest contig and the guanine and cytosine percentage in the genome (GC%) were observed. Kraken Metagenomics app was only able to classify 2.67% of reads, and of those reads only 17% of those reads identified the microbe as Lysinibacillus sphaericus. The quadratic streak was used 4 times to ensure a pure culture. Throughout the course of this study I isolated one colony and performed many physiological and genomic tests to identify what species my isolate was. A novel Gram-stain-positive, coccoid or short rod-shaped, moderate-orange-pigmented, halotolerant and psychrotolerant bacterium, designated strain SCU63 T, was isolated from a saline soil sample in China, and characterized by a polyphasic taxonomic approach. At the genus level, morphology can vary greatly. The literature on the Planococcus species like donghaensis, kocurii, halocryophilus and antarticus often notes how closely related the species are and how further analysis like G-C content, fatty acid strains, DNA-DNA hybridization etc1,2 are needed to differentiate the species. Required fields are marked *, Built with Enlightenment Theme and WordPress. Cell lysis was accomplished through adding sodium dodecyl sulfate (SDS), which is a surfactant that chemically weakened the cell walls, and the use of PowerBeads and the centrifuge to mechanically break the cell walls. BaseSpace’s SPAdes Gemone Assembler analyzed 128 contigs over 1000 base pairs (bp) long, a total length of over 3.7 million bp, the longest contig  was 196 thousand bp, and the GC% was 44.4%. I was unable to grow any microbes from the wood stove but the growth from the previously frozen wood was abundant. Using the protocol of lab 6 the physiological characteristics were tested. Colony morphology including color, size, margin and elevation was observed from growth on the TSA agar. Micrococcus lylae 6. Overnight grown pathogenic bacterial strains of 1 × 10 6 CFU/mL were treated with known concentration of biosurfactants and incubated at … The firewood pile was slowly decomposing, and it is likely that the microbe that was isolated from it was a part of the community that was utilizing the wood as an energy source. Many of the morphological and physiological analyses made on the isolate are not held by every species in the Planoccocus genus. Planococcus sp. Additionally the isolate underwent the thioglycolate test- for oxygen class, oxidase test- for the presence of cytochrome c-oxidase, and lastly the catalase test- for the presence of catalase enzyme. Considering the environment in which it was found, there were a few expected results: such as the microbe’s oxygen class and catalase test results. They may be domed, shining, mucoid-type colonies with radial striations or may appear smooth with entire edges. They are prokaryotic in nature meaning they are the earliest forms of the cell without a nucleus.. penetrates wall of decolorized gram - cells gram negative appear red. Micrococcus sedentarius 9. Sarcina, Catalase positive:Deinococcus,Marinococcus Micrococcaceae are not a coherent group. Planococcus faecalis sp. BLAST had a different database and could possibly have the genome of the isolates species if base space did not. Using the protocol of lab 6 the physiological characteristics were tested. Micrococcus nishinomiyaensis 7. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. This genus is relatively young and is currently growing with many of the species being described within the last ten years. Micrococcus halobius 3. These results reveal that the cells contained both cytochrome c-oxidase and the catalase enzyme respectively. The gram-stain was repeated three times before a successful stain was accomplished. The genotypic test results for this microbe were vague, the results of BaseSpace had a low number of reads that could be classified and of those reads there was little consensus. Melissococcus (2008). A gram-positive (gram-variable), beaded organism with delicate branching was recovered from the sputum of a 20-year-old patient with leukemia. The sample was stained using the provided protocol, gram-positives and negative controls were compared to the isolate to determine its gram-state (lab 4). While under the microscope it was observed that the cells could be aligned linearly, in pairs or quads but not in a longer strep chain. 1a). The isolate failed to grow on EMB or MAC plates, considering that both plates are selective for gram negative, these results confirm the results of the gram positive test: Image 4. Image 5 and 6 are from the Kraken app. BLAST provided many species level classifications with similar query cover and percent identity. Some of the notable differences between Micrococcus and Staphylococcus are: Staphylococcus in Gram Stain Both of these organisms are normal flora of skin and mucous membranes of man and animals. The morphological characteristics that are consistent with the isolate and across the genus are: gram-positive membranes, cocci cell shape, colonies are yellow orange in color, catalase positive and an aerobic oxygen class5. nov. isolated from cyanobacterial mat samples collected from ponds in Antarctica. The genus Planococcus was originally proposed by Migula [1] to accommodate Gram-stain-positive, aerobic and motile cocci of the family Planococcaceae in the phylum Firmicutes. Using Illumina’s BaseSpace dashboard to handle the data, the isolate’s genome was analyzed and compared to an existing database to search for similar sequences of DNA.
