Improvement of Bioinsecticides Production by Sporeless Bacillus thuringiensis strains in Response to Various Stresses in Low Cost Medium
(
Springer-Verlag
, 2011 , Article)
The use of bioinsecticides, particularly those produced by sporeless Bacillus thuringiensis strains, has been shown to be a good alternative in pest management. Two types of sporeless mutants were distinguished. The ...
Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology
(
Elsevier B.V.
, 2011 , Article)
Statistical experimental designs, involving a Plackett-Burman design followed by a rotatable central composite design were used to optimize the culture medium constituents for Bacillus thuringiensis bioinsecticide production. ...
Overproduction of Delta-Endotoxins by Sporeless Bacillusthuringiensis Mutants Obtained by Nitrous Acid Mutagenesis
(
Springer-Verlag
, 2011 , Article)
Asporogenic and oligosporogenic Bacillus thuringiensis mutants having the ability to overproduce insecticidal crystal protein were generated by using nitrous acid (50 mg/ml), as chemical mutagenic agent. Insecticidal crystal ...
Correlation between delta-endotoxin and proteolytic activities produced by Bacillus thuringiensis var. kurstaki growing in an economic production medium
(
Taylor & Francis
, 2013 , Article)
Bacillus thuringiensis is a Gram positive bacterium that produces an insecticidal crystalline protein making it one of the most important biocontrol agents for pest management. Bioinsecticides based on B. thuringiensis ...
