A colony of a yellow pigment forming, nonhemolytic Micrococcus species (tentatively identified as Micrococcus luteus) was found on a human blood agar plate close to a hemolytic staphylococcal colony. It was also noted that the zone of hemolysis of this Staphylococcus (the term Micrococcus is not used here for this organism to avoid confusion with the other) was slightly but definitely indented ...

Sodium polyanethol sulfonate (SPS) at 500 microgram/ml, but not sodium amylosulfate (SAS) at 500 microgram/ml, precipitated egg white lysozyme (1 mg and 50 microgram of lysozyme per ml) as determined with the assay strain Micrococcus lysodeikticus ATCC 4698. Fresh and heat-inactivated (56 degrees C, 30 min) human serum (80%, vol/vol) killed M. lysodeikticus (10(4) bacteria per ml at zero time) ...

The first total synthesis of marine-derived penicimonoterpene (±)-1 has been achieved in four steps from 6-methylhept-5-en-2-one using a Reformatsky reaction as the key step to construct the basic carbon skeleton. A total of 24 new derivatives of 1 have also been designed and synthesized. Their structures were characterized by analysis of their 1H NMR, 13C NMR and HRESIMS data. Some of them sho...

The promoters of Micrococcus luteus, a bacterium whose chromosomal DNA has a high G + C content (74%), diverge from the consensus prokaryotic promoter in having GC-rich DNA sequences at less important positions (Nakayama, M., Fujita, N., Ohama, T., Osawa, S., and Ishihama, A. (1989) Mol. Gen. Genet. 218, 384-389). In order to compare the promoter selectivity of RNA polymerase between M. luteus ...

The impact of steroid hormones, and particularly estradiol, on human microbiota could be recognized as a substantial part human-microbiota interactions. However, an area that remains poorly investigated is the skin vaginal microbial communities biofilms, which contain non-pathogenic bacteria phyla Firmicutes Actinobacteria, especially probiotic genus Lactobacillus widespread, safe genus, Microc...

Four bacteria, identified as Pseudomonas aeruginosa, Alcaligenes eutrophus, Bacillus subtilis and Micrococcus luteus were isolated from crude oil polluted soils using anthracene as the sole carbon and energy source. All the organisms utilized n-hexadecane, n-tetradecane, diesel oil, engine oil and naphthalene as sole carbon sources. None could utilize hexane, cycloheptane, xylene, benzene, tolu...
