World over sewage treatment plants are fighting algae bloom, when this algae can be effectively harvested and processed to obtain valuable oil that can be converted into Bio diesel. The equipment and knowledge required for the implementation of this process is available world over and at nominal costs , which is reducing by the day. The complicated part of this process is the separation of algae from water which currently has been made easy to a large extent.

Sewage treatment is done in different steps and the algae problem comes at around …

Ravichandra Potumarthi, a researcher in India, has demonstrated and presented his findings at a conference (the International Conference on Bioengineering and Nanotechnology) that using the enzyme lipase as the catalyst he can convert vegetable oils into biodiesel. The trouble, of course, with that, conceptually, is that lipase is a complex protein, difficult and expensive to synthesize. Naturally it would not be a significant breakthrough if Ravichandra did not start thinking “outside the box”, so to speak. He saw no reason to go to the trouble of refining the enzyme to …
