Isolation and production of newly oligosporogenic polyvalent Bacillus thuringiensis mutants for agricultural pest control
The study successfully generated oligosporogenic mutants of B. thuringiensis BLB1 with enhanced delta-endotoxin and enzyme production while reducing spore formation. The S6 mutant showed the highest bioactivity, and its production was further increased in a cost-effective way using date waste as a culture medium, highlighting its potential as a useful and eco-friendly biopesticide.
