Surfactants are a group of amphiphilic chemical compounds (ie, having both hydrophobic
and hydrophilic domains) that form an indispensable component in almost every sector of …

Biosurfactant production by three Bacillus subtilis strains (# 309,# 311 and# 573) isolated
from Brazilian crude oils was optimized based on different carbon and nitrogen sources. The …

In this work, biosurfactant production by Bacillus subtilis# 573 was evaluated using corn
steep liquor (CSL) as culture medium. The best results were obtained in a culture medium …

The world continues to rely heavily on petroleum as a primary energy source. However, a
great fraction of the oil-in-place remains inaccessible to traditional recovery means. This …

After conventional oil recovery operations, abundant residual oil is still trapped in pore
space of complex capillary network in the reservoir. As a promising method of tertiary oil …

The strains isolated from the formation water were characterized and screened considering
their crude oil degradation capability and biosurfactant production ability. The growth …

In recent years that reaching oil price to its minimum amount has become a critical issue in
petroleum industry, microbial enhanced oil recovery (MEOR) is a main topic of interest in …

A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by
conventional oil recovery methods. Further downstream, the petroleum industry is facing …
