Abstract: A process of synthesizing a peptide using an alkylene oxide as an acid scavenger is provided. A process of the present invention can be used in a solid phase or solution phase synthetic process where peptide synthesis occurs by the sequential addition of N-.alpha.-amino-Boc-protected residues followed by acid deprotection of that N-.alpha.-amino protecting group and scavenging of the acid.

Abstract: The invention relates to a mutant of Bacillus thuringiensis which produces a larger amount of crystal delta-endotoxin with a greater pesticidal activity as compared to the corresponding parental strain. The mutant may also have a larger crystal size as compared to the corresponding parental strain. The crystal delta-endotoxin produced by the mutant Bacillus thuringiensis will have an activity directed towards the same pest(s) as its parental Bacillus thuringiensis crystal delta-endotoxin. The invention further relates to a method for producing such a mutant, compositions comprising such a mutant as well as methods for controlling a pest(s) using these compositions.
