Abstract
Abstract A novel strain of Bacillus cereus, designated AS4-12, has been isolated from the environment. The strain AS4-12 is one of a number of B. cereus strains which are useful as biocontrol agents to combat fungal damping off disease in field crop plants, and strain AS4-12 has exhibited the best performance among a large number of natural isolates in fostering the emergence and growth of alfalfa plants under normal field conditions in the upper midwestern U.S.
