Hirai Y. 2012. (2006) suggested that data from the mid-1990s onwards should be considered for assessing the pathogenicity of M. luteus. Information submitted in response to the section 71 Notice indicates that M. luteus strain ATCC 4698 was not imported into or manufactured in Canada in 2008, except in limited quantities for academic research, teaching, and research and development activities. 2013). polyacrylonitrile polymers (Fischer-Colbrie et al. Micrococcus luteus  (Schroeter) Cohn (ATCC® 4698™). 2008). We were aiming to isolate a bacterium from this initial environmental sample by using repeated quadrant streaks to isolate single species colonies, therefore producing a pure culture that we could do a multitude of tests on which include Gram staining, genetic analysis and antibiotic testing along with many other tests.

Beitr Biol Pflanz 1:127–244. The confidence on that reading is decently confident, evidenced by the blue coloring. When looking at the genetic tests, most of the identified strains in the Korona test are Micrococcus luteus. Rickard AH, McBain AJ, Ledder RG, Handley PS, Gilbert P. 2003. Molecular Microbiology 46(3):611-21. 2011). Characterization of Micrococcus antarcticus sp. However, in some mixed cultures, M. luteus is quickly outcompeted and becomes undetectable because of antagonism by other micro-organisms, such as Pseudomonas aeruginosa and S. aureus (Malic et al. FEMS Microbiology Letters 104(3-4):271-86.

2014). 2013 unless referenced otherwise. 961-71): Springer New York. When applicable, literature searches conducted on the organism included its synonyms, and common and superseded names.

Based on the place of origin of the bacterium that I isolated, I hypothesize that it will either be one of the above bacterium or a similar water loving organism, likely one that also forms a biofilm. Micrococcus luteus uses the amino acids and does not grow in the butt of the slant. “Micrococcus – Public Health Agency of Canada.”, Public Health England. M. luteus appears to be a normal inhabitant of aquatic ecosystems, yet no adverse effects of M. luteus on aquatic invertebrates have been reported in the literature. US Patent No: 4,666,838.

Applied and Environmental Microbiology 56(12):3649-56. nutrient agar supplemented with 0.5% w/v L-lactate and 0.05% yeast extract) the doubling time is approximately 4 hours (Kaprelyants and Kell, 1993). They are fairly ubiquitous in the environment, and are small (0.5 to 3.5 micrometers in diameter) and non-motile. Intro: Microbes are everywhere, even in the most extreme environments and conditions. Recovery of Micrococcus luteus and presumptive Planococcus from moribund fish during outbreaks of rainbow trout (Oncorhynchus mykiss Walbaum) fry syndrome (RTFS) in England. Królasik J, Zakowska Z, Krȩpska M, Klimek L. 2010. International Journal of Systematic Bacteriology 47 (2): 590–2. Micrococcus can also be phylogenetically differentiated from Staphylococcus based on 5S rRNA sequences (Dekio et al. Pathogens and Disease 69(2):142-8.

Hazards related to micro-organisms used in the workplace should be classified accordingly under the Workplace Hazardous Materials Information System (WHMIS)Footnote 5 . Micrococcus luteus. The gelatinase test can be used to differentiate between Staphylococcus Process for preparing 2,6-diaminopurine-2'-deoxyriboside and 2'-deoxyguanosine. The rpf gene of Micrococcus luteus encodes an essential secreted growth factor. No other adverse effects in aquatic or terrestrial plants have been attributed to M. luteus. 1986. 1974). 2010.

Micrococcus and Stomatococcus spp. StrainInfo introduces electronic passports for microorganisms. Methods: To start isolating the bacterium, I used a sterile swab wet with deionized water provided by the lab to pick up bacteria from the shower drain. 2013. They are fairly small as well, usually about a millimeter in diameter and of a normal height. 2006). 1976). Microbial Ecology 58:461-73.

There are no reports in the publicly available literature clearly implicating M. luteus strain ATCC 4698 in adverse effects on humans. M. luteus strain ATCC 4698 has one of the smallest genomes of any free-living actinobacterium sequenced to date, which consists of a single circular chromosome spanning 2,501,097 bp with 73% G+C content and encoding 2,403 predicted proteins, (Young et al.
