Journal ArticleDOI
Purification of the insecticidal toxin in crystals of Bacillus thuringiensis.
TL;DR: It is concluded that the trypsin-resistant polypeptide represents the active insecticidal toxin of the crystal and was active by injection and ingestion.
Journal ArticleDOI
An ABC transporter from Bacillus thuringiensis is essential for β-exotoxin I production
Sylvain Espinasse,Michel Gohar,Didier Lereclus,Didier Lereclus,Vincent Sanchis,Vincent Sanchis +5 more
TL;DR: The demonstration that berAB is required for beta-exotoxin I production and/or resistance in B. thuringiensis adds an adenine nucleotide analog to the wide range of substrates of the superfamily of ABC proteins.
Journal ArticleDOI
Combined analysis of supernatant-based feeding bioassays and PCR as a first-tier screening strategy for Vip -derived activities in Bacillus thuringiensis strains effective against tropical fall armyworm.
TL;DR: Results suggest the insecticidal effectiveness of putative VIPs in B. thuringiensis isolates can be preliminarily estimated by the use of supernatant‐derived total protein in feeding experiments, though only in a limited manner.
Journal ArticleDOI
Effect of shear stress on cultivation of Bacillus thuringiensis for thuringiensin production
TL;DR: It was found that shear stress had a significant effect on thuringiensin production during the stationary phase, and by decreasing the agitation speed during the static phase, product formation was increased up to 43%.
Journal ArticleDOI
Correspondence of High Levels of Beta-Exotoxin I and the Presence of cry1B in Bacillus thuringiensis
Sylvain Espinasse,Michel Gohar,Josette Chaufaux,Christophe Buisson,Stéphane Perchat,Vincent Sanchis,Vincent Sanchis +6 more
TL;DR: It is concluded that strains carrying cry1B and vip2 genes also possess, on the same plasmid, genetic determinants necessary to promote high levels of production of β-exotoxin I.
