Isolation and characterization of biosurfactant/bioemulsifier-producing bacteria from petroleum contaminated sites 

 -  Bioresource Technology, 97(6), p.868-875, 2006 .
<br/><br/> Biosurfactant-producing bacteria were isolated from terrestrial and marine samples collected in areas contaminated with crude oil or its byproducts. Isolates were screened for biosurfactant/bioemulsifier production in different carbon sources (glucose, fructose, sucrose and kerosene)using the qualitative drop-collapse test. Glucose produced the highest number of positive results (17 of 185 isolates). All 17 isolates produced emulsions with kerosene and 12 exhibited high emulsion-stabilizing capacity, maintaining 50
