Biodegradation Of Diflufenican Using Anaerobic Microbial Consortia, Velukumar T. Nanjagowder

Theses

In this thesis I examine the feasibility of using anaerobic microbial consortia from digested anaerobic sludge to degrade Diflufenican, a fluorinated herbicide released into the environment as a result of agricultural usage. The compound is manufactured by Rhone Poulenc and it is an active ingredient of agricultural herbicides. The anaerobic digested sludge served both as a source of microorganisms and as a growth medium. Initial studies were conducted by making a stock solution of 1 ppm concentration of Diflufenican in acetone, the optimal solubility of the compound as suggested in the material safety data sheet is 0.05 ppm in water. …
