Engineered membrane super channel improves bioremediation potential of dioxin-degrading bacteria

Article Abstract:

Two related Sphingomonads, namely the dioxin-degrading Sphingomonads wittichii RW1 and the polypropylene glycol-degrading Sphingomonads subarctica IFO 16058, are engineered to incorporate specialized membrane structures into their cell membrane. In both the cases the bioremediation capability of the organisms is substantially increased pointing at the potential of this approach as a general strategy to improve bacterial degradation hazardous compounds in the environment.

A scorpion neurotoxin increases the potency of a fungal pesticide

Article Abstract:

Study is presented to demonstrate that high-level expression of an insect-specific neurotoxin from the scorpion Androctonus australis in hemolymph by M. anisopliae increases the fungal toxicity 22-fold against tobacco hornworm (Manduca sexta) caterpillars and nine times against yellow fever mosquitoes (Aedes aegypti) without compromising the host specificity.

Taming the uncultured

Article Abstract:

Agricultural biotechnology is challenged by the need to develop solutions for the prevention of powdery mildew fungi, which causes persistent diseases of crops. Barley and wheat in North America and Europe are particularly vulnerable.
