Microbiology & Molecular Biology

Head of the Division: Dr. S. Poopathi, Scientist-G

Isolation of new mosquitocidal bacteria from various environmental sources such as Bacillus thuringiensis israelensis, B.cereus, B.subtilis, B.fusiformis, B.mobilis for mosquito control were studied.

  • The mosquitocidal toxins from newly isolated bacterial agents were characterized.
  • The extra cellular toxins from culture free medium of mosquitocidal bacteria was tested through oviposition attraction. The results are promising.
