Investigation of extrachromosomal DNA pattern in Bacillus thuringiensis Berliner and Bacillus sphaericus Meyer et Neide.

摘要

Analysis of the pattern of extrachromosomal DNA in different cultures of Bacillus thuringiensis and B. sphaericus demonstrated a higher content of extrachromosomal DNA in B. thuringiensis than in B. sphaericus. The quantity and approximate molecularweights of the plasmids were determined. The assumption that the plasmid DNA content in B. thuringiensis strains is higher than in the other representatives of the genus Bacillus was confirmed.
