The culture suspension of CHM1, drenched around the root of rice and cole (Brassica napus), promoted seedling growth. The data here showed that Bacillus sp. CHM1 could be a potential agent to protect maize, horsebean, cole and rice (Oryza sativa)plants from infection by pathogenic fungi in vivo and had properties as a plant growth-promoting endophytic bacterium (PGPE).
