SCREENING AND EXTRACTION OF BIOSURFACTANT GENERATING BACTERIA FROM OIL INFCTED SOILS By, Poulina Saxena, Harshad Meer, Journal ID: AJAHS ...

The terms biosurfactant and bioemulsifier have often been used interchangeably to describe surface active biomolecules. However, it is important to note that there are marked differences between them especially based on their physicochemical properties and physiological roles. Although bioemulsifiers and biosurfactants are both amphiphilic in nature and are produced by a wide range of ...

Firstly, two biosurfactantproducing bacteria named 1# and 2# was selected from 7 strains. Secondly, their growth and metabolism laws that the quantity of metabolic products would reach the highest and the value of surface tension would bottom out in the stationary phase of growth was found in the culture flask. Thirdly, the optimal condition for fermenting was chose by the orthogonal test ...

different groups of biosurfactants, that include solubility of hydrophobic compounds, heavy metal binding, bacterial pathogenesis, cell adhesion and aggregation, quorum sensing, and biofilm formation [2, 3]. Bacteria are the main group of biosurfactantproducing microorganisms, although they are also produced by some

where IFT measurement was used as a part of screening methodology for BS (BE) production. Apart from screening, this study also analyzes the credibility of the use of hydrophobic and hydrophilic substrates like crude oil, glucose and glycerol for the growth of BS (BE) producing bacteria isolated from crude oil contaminated environment.

Biosurfactants produced by bacteria are surface active compounds involved in the degradation of hydrocarbons. They are heterogeneous group of surface active molecules produced by microorganisms, which adhere to the cell surface or are excreted extra cellularly in the growth medium.

1. Definition of Biosurfactants: Biosurfactants can be defined as amphipathic molecules with both hydrophilic and hydrophobic (generally hydro carbons) moieties that partition preferentially at the interface between fluid phases with different degrees of polarity and hydrogen bonding such as oil/water or air/water interfaces.

Les écosystèmes aquatiques hypersalins des Chotts, Sebkhas et eaux pétrolières salines (eaux de gisement) ont été peu étudiés. Ils sont pourtant potentiellement riches en microorganismes adaptés à ces milieux extrêmes. Nous analyserons les communautés de microorganismes de ces écosystèmes (microorganismes halophiles) par une approche culturale et moléculaire. Nous rechercherons ...

influence biosurfactants production by microorganisms. They are mainly produced by hydrocarbon utilizing microorganisms exhibiting surface activity. In this work we describe the isolation of biosurfactant producing bacteria from oil contaminated sites near petrol bunk, motor vehicle service station and diesel loco sheds.
