Induction of microcycle sporulation in Bacillus brevis spp. AG4 by amethopterin.

Addition of amethopterin to medium before inoculation inhibited DNA synthesis and induced microcycle sporogenesis in Bacillus brevis spp. AG4. Synthesis of RNA and proteins occurred at a considerably reduced rate.

Study of inhibition of outgrowth in Bacillus cereus T by ethyl picolinate.

The effects of ethyl picolinate on germination, outgrowth, and sporulation of Bacillus cereus T were studied in a synthetic medium containing glucose. Ethyl picolinate specifically inhibited at two stages, outgrowth and sporulation. The initiation of germination and cell division was not affected.
