Identification of beta-exotoxin production, plasmids encoding beta-exotoxin, and a new exotoxin in Bacillus thuringiensis by using high-performance liquid chromatography.

摘要: An improved high-performance liquid chromatography separation was developed to detect and quantify beta-exotoxin production in Bacillus thuringiensis culture supernatants. Exotoxin assigned a plasmid five strains, from three subspecies (B. subsp. serotype 1, B. tolworthi 9, darmstadiensis 10). A new exotoxin, called type II this report, discovered morrisoni 8ab, purified, partially characterized. This material is more specific than I very active against the Colorado potato beetle, Leptinotarsa decemlineata.
