Production of the lepidoptera-specific crystal protein by a local isolate of Bacillus thuringiensis

A local isolate of Bacillus thuringiensis (B.t.81) produced crystal protein which was identified as a cry I gene of Class I. The synthesis and assembly of crystal complements were investigated at intervals throughout the growth cycle. Incubation temperature had a marked effect on toxin synthesis; pr...

Beschreibung
Zusammenfassung:	A local isolate of Bacillus thuringiensis (B.t.81) produced crystal protein which was identified as a cry I gene of Class I. The synthesis and assembly of crystal complements were investigated at intervals throughout the growth cycle. Incubation temperature had a marked effect on toxin synthesis; production being the highest at 25 degree C and the lowest at 42 degree C. The mutants of B. t. 81, unable to synthesize crystal protein complements, have also been described.
