| Abstract: | A transgenic strain of the nitrogen-fixing filamentous cyanobacterium Anabaena PCC 7120 protected expressed δ-endotoxin proteins of Bacillus thuringiensis subsp. israelensis from damage inflicted by UV-B, a sunlight component that penetrates Earth's ozone layer. This organism, which serves as a food source to mosquito larvae and could multiply in their breeding sites, may solve the environment-imposed limitations of B. thuringiensis subsp. israelensis as a mosquito biological control agent.
