Production, purification and characterization of biosurfactant from Geobacillus thermoleovorans and studying its antimicrobial and antitumor activity
The ten bacterial isolates used in this study have the ability to utilizecrude oil and aromatic compounds. They were isolated in the previousstudy and considered as a novel group of aromatic hydrocarbon degradingextreme thermophillic bacteria. These isolates were screened for theirability to produce biosurfactant depending on the emulsification index(E24%), surface tension measurement (mN/m) and emulsification activity(E.A) using crude oil as a carbon source.
