Isolation and Characterization of Gram-Positive Biosurfactant-Producing Halothermophilic Bacilli From Iranian Petroleum Reservoirs
BACKGROUND Petroleum reservoirs have long been known as the hosts of extremophilic microorganisms. Some of these microorganisms are known for their potential biotechnological applications, particularly production of extra and intracellular polymers and enzymes. OBJECTIVES Here, 14 petroleum liquid samples from southern Iranian oil reservoirs were screened for presence of biosurfactant-produci...

متن کاملIsolation of Biosurfactant Producing Bacteria from Oil Reservoirs
Biosurfactants or surface-active compounds are produced by microoaganisms. These molecules reduce surface tension both aqueous solutions and hydrocarbon mixtures. In this study, isolation and identification of biosurfactant producing bacteria were assessed. The potential application of these bacteria in petroleum industry was investigated. Samples (crude oil) were collected from oil wells and 4...
متن کاملPost-neurosurgical meningitis; gram negative bacilli vs. gram positive cocci
Background: Post-neurosurgical meningitis is a significant cause of mortality and morbidity. In this study we aimed to compare the differences of clinical, laboratory features and outcomes between the post-neurosurgical meningitis caused by gram-negative bacilli (GNB) and gram-positive cocci (GPC). Methods: Cases of post-neurosurgical meningitis (with positive CSF culture) were included. After...
متن کاملcharacterization of novel biosurfactant producing strains of bacillus spp. isolated from petroleum contaminated soil
background and objectives: biosurfactants are surface active agents with broad range commercial applications in various industries and have considerable advantages over their chemical counterparts. materials and methods: in this study, bacteria were isolated from contaminated and uncontaminated soil and selected during preliminary screening using hemolytic activity, oil spreading and oil collap...
