Process for the production of L-aspartyl-L-phenylalanine esters. YGJ1 hydrolyzing phthalate esters. Martin DJH, Denyer SP, McDonnell G, Maillard JY. M. luteus strain ATCC 4698 is susceptible to 0.03% chlorine dioxide, 7.5% hydrogen peroxide or 2.25% peracetic acid, causing >5 log10 reduction in cell viability after 30 seconds exposure (Martin et al. Ecotoxicology 14:14-299. Piersen CE, Prince MA, Augustine ML, Dodson ML, Lloyd RS. Rusin PA, Rose JB, Gerba CP. Under the microscope they are round cells. I also had to do the thyoglycate test 3 times to get a conclusive result, further making me skeptical of how active the culture was during the physical tests during week 6, which is where almost all of the inconsistencies arose. 2010). Journal of Bacteriology 192(3):841-60. Microbiology (Reading, England) 148(Pt 8):2479-87. Moreover, the organism lacks genes for synthesis and assembly of flagella and this fact alone serves to cast very serious doubt on identification of the causative organism as M. luteus. Identification using fatty acid methyl ester analysis has been reported to yield false positives for M. luteus, requiring the identification to be confirmed by the observation of Gram positive cocci (Oka et al. Tiago I, Chung AP, Veríssimo A. 2013 unless referenced otherwise. Organisms commonly found on the body include Micrococcus, Staphylococcus, and Corynebacterium species (Dermnet New Zeland). International Journal of Systematic and Evolutionary Microbiology 50(2):715-9. ATCC. ScienceDaily, 6 August 2013. Presently, the genus Micrococcus includes 10 species (LPSN, 2015): Taxonomic differentiation of Micrococcus species is more reliable by 16S rRNA gene sequence analysis, using Micrococcaceae-specific signature nucleotides at positions 293-304, 610, 598, 615-625, 1025-1036, 1026-1035, 1265-1270 and 1278 according to Escherichia coli numbering (Wieser et al., 2002). Most strains of Staphylococcus aureus produce coagulase while M. luteus strain ATCC 4698 does not (Mortensen and Kocur, 1967). Pursuant to paragraph 74(b) of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health are required to conduct screening assessments of living organisms added to the Domestic Substances List (DSL) by virtue of section 105 of the Act, to determine whether they present or may present a risk to the environment or human health (according to criteria as set out in section 64 of CEPA)Footnote 1 . The human hazard potential of M. luteus strain ATCC 4698 is assessed to be low. 2008. Hazards related to micro-organisms used in the workplace should be classified accordingly under the Workplace Hazardous Materials Information System (WHMIS)Footnote 5 . M. luteus strain ATCC 4698 is susceptible to antibacterial compounds produced by other micro-organisms, which could make it a poor competitor outside of its niche environment. 2001); 28 cases of bacteremia after medication with central venous catheters were identified in a seven-year survey from 2002 to 2008 (Hirata et al. If I were to continue researching this isolate, I would redo the API 20 E test strip with a fresh, active culture to ensure that it can reduce nitrate, and also the oxidase test to ensure that it does have cytochrome c oxidase present, which it should according to Public Health England. 1996); some psychrotrophic bacterial strains isolated from Antarctica (Lo Giudice et al. 2011. The catalase test did return positive by bubbling, indicating that it does have the ability to break down the radical hydrogen peroxide into diatomic oxygen and hydrogen. Cold (4°C), dryness (2.5% humidity) and starvation increased the survival of M. luteus in soil (Casida, 1980a), possibly by creating unfavorable growth conditions, and thereby inducing dormacy (Dib et al. Kaprelyants AS, Gottschal JC, Kell DB. Minimum structure of peptidoglycan required for induction of antibacterial protein synthesis in the silkworm, Bombyx mori. Diversity of 746 heterotrophic bacteria isolated from microbial mats from ten Antarctic lakes. Most M. luteus infections, and particularly urinary tract infections, reported before the mid-1990s were later re-identified as Staphylococcus. 1976). Many of the tests did line up with M. luteus though, such as the fluid thyoglycate test, which showed that it was an obligate aerobe. an ingredient in sunscreen (SINTEF, 2013). a skin treatment composition for odour control and biocontrol of bacterial skin disorders (Tagg et al. 2001; Prado et al. Inoculation of corn (Zea mays) with this strain increased the number of leaves, shoot and root length, and increased dry weight per gram of fresh weight by 54% (Raza and Faisal, 2013).
