Abstract

Present study consists 18 morphologically different marine bacterial species isolated from coastal Tamil Nadu, examined for production of bioemulsifiers. All the 18 isolate produces bioemulsifiers and exhibit emulsification index (E24) of 85-95% with hydrocarbons containing fatty acids and <75% with other hydrocarbons. Resultant emulsion found stable till day 100 without any phase separation. Polymeric protein nature of the bioemulsifiers produced by the marine bacterial species could be the reason for the stability. Hypothesis involved in the biosynthesis of bioemulsifiers and the formation of phenomenal stable emulsions are also discussed in the present study.
