Seven strains of Bacillus mucilaginosus were screened from rhizosphere soil of Kentucky bluegrass,and their physiological and biochemical characters,salt tolerance,acid and alkali resistance,and temperature sensitivity were determined in this study.The results of this study showed that all strains were G-,produced circular gemma and thick capsule.The catalase and lysozyme test on seven strains of Bacillus mucilaginosus were masculine.The hydrolyzed starch,V.P lecithinase and indole test on seven strains of Bacillus mucilaginosus were feminine.All strains survived in the medium with 1%~2% NaCl and grew well under the temperature ranging from 25~30 ℃.
