Actinobaceria, Micrococcus luteus SUBG006 was isolated from infected leaves of Mangifera indica L. vr. Nylon in Rajkot, (22.30°N, 70.78°E), Gujarat, India. The genome size is 3.86 Mb with G + C content of 69.80% and contains 112 rRNA sequences (5S, 16S and 23S). The whole genome sequencing has been deposited in DDBJ/EMBL/GenBank under the accession number JOKP00000000.

A new peptide antibiotic, cypemycin, with a molecular weight of 2,097 (M+H), was isolated from the culture broth of Streptomyces sp. OH-4156. The antibiotic possesses cytocidal activity against P388 leukemia cells in vitro at a concentration of 1.3 microgram/ml (IC50 values), and the antibiotic showed antimicrobial activities against Micrococcus luteus (MIC, 0.2 microgram/ml).

We have investigated the effects of tyrosine nitration (to form the weak acid, 3-nitrotyrosine) at positions 23 or 20 plus 23, on the structure and function of hen egg-white lysozyme. Enzyme activity against Micrococcus luteus cell-wall fragments or soluble substrates exhibits two phenomena. (a) A decrease in Km and kcat for the hydrolysis of soluble oligo- and poly-saccharides, resulting in on...

Calotropis gigantea is a common wasteland weed and known for various medicinal properties. The aim of the present study was to screen leaves of Calotropis gigantea for the antimicrobial activity against clinical isolates of bacteria. The aqueous extract of the C. gigantea was studied for its antagonistic activity against Staphylococcus aureus, Escherichia coli, Bacillus cereus, Pseudomonas aeru...

Crude extracts prepared from four Micrococcus varians strains, 11 M. luteus strains and four laboratory isolates subsequently classified with M. luteus were assayed for catalase activity following electrophoresis on polyacrylamide gels. The enzyme patterns produced from the M. varians strains exhibited three catalase isoenzymes which were distinguished into two types of patterns depending upon ...

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 ...
