characterization of solvent stable extracellular protease from bacillus koreensis (bk-p21a).a total of 18 protease producing bacterial strains were isolated from detergent effluent in south korea using skim milk agar medium. a strain (bk-p21a) was selected and identified as bacillus koreensis based on morphological, biochemical and molecular characterizations (16s rrna gene sequence analysis). optimized culture conditions for the production of protease were ph 8.5, 30 °c, sucrose (2%) and yeast extract (0.2%) during 36 h of incubation. furthermore, the protease was partially purified b ...201323485830
bacillus koreensis sp. nov., a spore-forming bacterium, isolated from the rhizosphere of willow roots in endospore-forming, rod-shaped bacterium was isolated from the rhizosphere of willow roots in korea. the bacterium, designated strain br030t, was a strictly aerobic, motile rod. the cell wall contained type a1gamma peptidoglycan with meso-diaminopimelic acid as the diagnostic diamino acid. the major cellular fatty acids were anteiso-c(15 : 0), iso-c(15 : 0), iso-c(14 : 0) and iso-c(16 : 0). the major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanola ...200616403867
