“…Our study on the taxonomy of the genera Micrococcus and Zhihengliuella revealed that Micrococcus lactis MCC 2278 T and Zhihengliuella aestuarii JCM 16166 T , both described in 2011 (Chittpurna et al , 2011; Baik et al , 2011), showed high levels of 16S rRNA gene sequence similarity (99.3 %) and formed a cluster distinct from other members of the genera Micrococcus and Zhihengliuella and other genera of the family Micrococcaceae . Higher levels of sequence similarity and clustering of M. lactis MCC 2278 T and Z. aestuarii JCM 16166 T in phylogenetic trees raised concerns about the current taxonomic status of these two organisms.…”

“…In contrast to other members of the genus Zhihengliuella , Z. aestuarii JCM 16166 T did not contain a significant amount of anteiso-C 17 : 0 . The peptidoglycan interpeptide bridges of M. lactis MCC 2278 T and Z. aestuarii JCM 16166 T were l -Lys–Asp (Chittpurna et al , 2011) and l -Lys– l -Ala– d -Glu (Baik et al , 2011), respectively, both classified as type A4α (Schleifer & Kandler, 1972). Polar-lipid profiles of the two strains are shown in Fig.…”

Micrococcus lactis and Zhihengliuella aestuarii were described independently in 2011. Their type strains showed high levels of 16S rRNA gene sequence similarity (99.3 %). Phylogenetic analysis revealed that M. lactis MCC 2278 T and Z. aestuarii JCM 16166 T formed a monophyletic group and showed distant relationships to other members of closely related genera such as Micrococcus, Zhihengliuella, Arthrobacter and Citricoccus. The presence of large proportions of iso-C 14 : 0 and iso-C 16 : 0 with small amounts of iso-C 15 : 0 distinguished M. lactis MCC 2278 T and Z. aestuarii JCM 16166 T from other members of the genera Micrococcus and Zhihengliuella. Unlike other members of the genera Zhihengliuella and Micrococcus, M. lactis MCC 2278 T and Z. aestuarii JCM 16166 T showed growth at low concentrations of NaCl. Thus, based on distinctive phylogenetic, chemotaxonomic and physiological features of these two organisms in comparison with other members of the genera Micrococcus and Zhihengliuella, it is clear that they do not fit within the existing classification and deserve separate status. DNA-DNA hybridization between the two type strains was 63 %, indicating that they represent separate species. In this study, we propose the creation of a novel genus, Neomicrococcus gen. nov., to accommodate the two species with Neomicrococcus aestuarii gen. nov., comb. nov. (type strain JCM 16166 T 5KCTC 19557 T) as the type species. Neomicrococcus lactis comb. nov. (type strain MCC 2278 T 5DSM 23694 T) is also proposed.

Background: There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect pollinators. Mosquitoes consume nectar and can pollinate flowers. We identified microbes isolated from nectar of common tansy, Tanacetum vulgare, elucidated the microbial odorants, and tested their ability to attract the common house mosquito, Culex pipiens. Results: We collected 18 microbial isolates from T. vulgare nectar, representing at least 12 different taxa which we identified with 16S or 26S rDNA sequencing as well as by biochemical and physiological tests. Three microorganisms (Lachancea thermotolerans, Micrococcus lactis, Micrococcus luteus) were grown on culture medium and tested in bioassays. Only the yeast L. thermotolerans grown on nectar, malt extract agar, or in synthetic nectar broth significantly attracted C. pipiens females. The odorant profile produced by L. thermotolerans varied with the nutritional composition of the culture medium. Surprisingly, all three microbes grown separately, but presented concurrently, attracted fewer C. pipiens females than L. thermotolerans by itself. Conclusions: Floral nectar of T. vulgare contains various microbes whose odorants contribute to the odor profile of inflorescences. In addition, L. thermotolerans produced odorants that attract Cx. pipiens females. As the odor profile of L. thermotolerans varied with the composition of the culture medium, we hypothesize that microbe odorants inform nectar-foraging mosquitoes about the availability of certain macro-nutrients which, in turn, affect foraging decisions by mosquitoes.

“…Micrococcus sp. is one of that microorganisms which is widespread in the environment (water, soil, air, Antarctica, active sludge, human body, whey, roots of plants …) [14][15][16]. The spread of this genus makes it vulnerable to the development of enzymatic systems capable of dealing with different conditions in environments, as well as its ability to produce biosurfactant, which have important role in bioremediation of hydrocarbons, Figure 1 shows role of biosurfactants in emulsification of hydrocarbons and lowering of interfacial tension [17,18].…”

The importance of this study is that it is deals with the Barada River pollution with hydrocarbons (crude oil and its derivatives), as well as evaluating the ability of different types of Micrococcus sp. to bioremediation of hydrocarbons. Ten strains of Micrococcus sp. were isolated from the water samples from Barada River in Damascus, and these isolated were classified depending on Bergey's manual to four species: M. luteus, M. lylae, M. flavus, and M. antarcticus. The crude oil dependent growths of these isolates were assessed for 15 days at 30°C by monitoring the gradient fluxes in pH, optical density OD and total viable count TVC in the medium. The result was statistically supported by applying the One-way ANOVA test and the Paired sample t-test. The results showed that activity of species was best at the concentration of 2% of crude oil, and the species of M. lylae was best in dealing with crude oil, although this superiority between species was not supported at the statistical studying. In general, the different species of Micrococcus sp. have a good ability to deal with the different concentrations (1, 2 and 3%) of crude oil. And this supports research which encourages the use of this genus in the bioremediation. This research was indicated to the ability of M. lylae to deal with different concentrations of crude oil, which was not mentioned in previous research KEYWORDS
