Transformation in Bacillus subtilis was found to be significantly increased in the presence of lactose, sucrose, and maltose. It was further noted that electrical stimulation increased the frequency of transformation much as did the disaccharides. On the other hand, genetic transformation of the "protoplast" of Bacillus subtilis could not be demonstrated. These data are discussed in relation to the competent state.application/pdfenThis item is protected by copyright but is made available here under a claim of fair use (17 U.S.C.
