The dental plaque biofilm is at origin of the pathogenic mechanisms of the periodontal lesions, resulting both from the direct degradative action and the indirect inflammatory lesions, mediated by microbial cells and their virulence factors. The purpose of this study was the isolation, identification and characterization of the antibiotic susceptibility profiles of bacterial strains isolated fr...

Micrococcus luteus is a predominant member of skin microbiome. We here report on the genomic analysis of Micrococcus luteus strain O'Kane that was isolated from an elevator. The partial genome assembly of Micrococcus luteus strain O'Kane is 2.5 Mb with 2256 protein-coding genes and 62 RNA genes. Genomic analysis revealed metabolic versatility with genes involved in the metabolism and transport ...

A medicinal plant is any which has therapeutic used and are for drug production. The use of plants traditional uses well known in rural areas many developing countries. This study was undertaken to evaluate the antibiotic importance extracts Hunteria umbellata against selected clinical isolates cause diseases man. Agar diffusion method determine antibacterial activity umbellata. proximate compo...

1. The walls of Micrococcus sp. A1contain about 43% of a phosphorylated polymer. It was extracted with cold trichloroacetic acid and purified by chromatography on DEAE-cellulose. 2. The polymer contained equimolar amounts of d-glucose, N-acetylgalactosamine and phosphate, and was readily hydrolysed under gentle acidic conditions to a phosphorylated disaccharide. 3. Chemical and enzymic degradat...

Antibacterial peptides were isolated from immune haemolymph of Rhinoceros beetle (Oryctes rhinoceros L.) larvae and evaluated for antibacterial activity against bacterial pathogens, viz., Klebsiella pneumoniae, Micrococcus luteus, Bacillus subtilis, Paenebacillus macerans and Pseudomonas sp. The peptides were found to be stable upto 37°C and antibacterial activity observed at pH 7.0. The peptid...

A new strain belonging to the genus Collimonas was isolated from the sea surface microlayer off the coast of Trøndelag, Norway. The bacterium, designated Collimonas CT, produced an antibacterial compound active against Micrococcus luteus. Subsequent studies using LC-MS identified this antibacterial compound as violacein, known to be produced by several marine-derived bacteria. Fragments of the ...

We studied the growth and capacities for pesticides removal of bacterial strains isolated from the Laguna Grande, an oligotrophic lake at the South of Spain (Archidona, Málaga). Strains were isolated from water samples amended with 10 and 50 microg/ml of nine pesticides: organochlorinated insecticides (aldrin and lindane), organophosphorous insecticides (dimetoate, methyl-parathion and methidat...

The volatile oil from the stem bark of Scutia buxifolia (Rhamnaceae) has been obtained by hydrodistillation and analyzed by GC-MS. Twenty-one components were identified representing 99.93 % of the total oil composition, spathulenol (35.87%), β-cubebene (17.26%), germacrene D (6.43%), linalool (5.19%), carvacrol (4.05%) were the main components of S. buxifolia essential oil. Antioxidant and anti...
