Isolation of Plasmid-Harboring Serratia plymuthica from Facultative Gut Microflora of the Tobacco Hornworm, Manduca sexta.
Aseptic isolation of the facultative gut microflora of the tobacco hornworm, Manduca sexta, yielded four microorganisms. Two were gram-positive Bacillus spp., one was Serratia plymuthica, and another was the yeast Candida guilliermondii. The three bacterial species were screened for extrachromosomal DNA, and S. plymuthica was found to have a 6.4-kilobase plasmid, which was designated pCP-1.
