Summary
Conventional chemically-defined media were found to be inadequate for extensive batch culture growth of an asporogenous mutant of Bacillus subtilis certified as an HV-1 host for recombinant DNA. We developed a chemically-defined medium for rapid and extensive growth of one such strain, BGSC-1S53. The medium contains no components requiring separate sterilization. It is also useful for the prototrophic 168 strain (from which 1S53 was derived), a triple auxotroph of 168, and a highly debilitated (HV-2) 168 strain (BGSC 1S76) upon addition of the specific growth factors required by these strains. Excellent growth was also obtained with W-23, a Bacillus subtilis strain unrelated to the 168 series.
