Explanation

Pseudomonas putida is used in bio-remediation, and is the world’s first patented organism. Thiobacillus thiooxidans can use sulfur and convert it into sulfuric acid, which can be used in Bio leaching. Bacillus thuringiensis is bacteria that produce a toxin called Bt toxin due to its plasmid, that kill insects. Thus it is used as bio-insecticides.  Ralstonia eutropha bacteria contain oxygen tolerant hydrogenases that are being used to investigate use in bio fuels. Anabaena is a filamentous cyanobacteria that can fix atmospheric nitrogen and thus is used as bio fertilizer.
