Abstract
Abstract A novel strain of Bacillus cereus, designated DGA34, has been isolated from the environment. The strain DGA34 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, in part because of their production of the antibiotic zwittermicin A. Strain DGA34 has exhibited the best performance among a large number of natural isolates in producing the highest titer of zwittermicin A production.
