“…The term surfactant (SURFace ACTive AgeNTS) includes a wide variety of compounds, both synthetic and biological, but all of which have similar tension active properties [12,13]. Biosurfactants (biological surface active compounds or microbial surface active agents) are the biomolecules produced by living cell, mainly by microorganisms.…”

“…Production medium designed with glucose (2% w/v) and corn oil (10% v/v) successfully utilized by ATCC 22214 and demonstrated reduction in SFT (28.56+0.42 mN/m) and IFT (2.13+0.09 mN/m). SPLs are quite stable at 13-15% salinity, pH of wide range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), and temperature upto 100°C. Elshafie et al [67] were successful to demonstrate the role of SPLs in enhancing oil recovery (27.27% of residual oil (Sor) recovery) using core-flooding experimental set up under reservoir conditions.…”

Abstract:A strong developed bio-based industrial sector will significantly reduce dependency on fossil resources, help the countries meet climate change targets, and lead to greener and more environmental friendly growth. The key is to develop new technologies to sustainably transform renewable natural resources into bio-based products and biofuels. Biomass is a valuable resource and many parameters need to be taken in to account when assessing its use and the products made from its. The bioeconomy encompass the production of renewable biological resources and their conversion into food, feed and bio-based products (chemicals, materials and fuels) via innovative and efficient technologies provided by industrial biotechnology. The paper presents the smart and efficient way to use the agro-industrial, dairy and food processing wastes for biosurfactant's production. Clarification processes are mandatory to use the raw substrates for microbial growth as well as biosurfactant production for commercial purposes. At the same time it is very essential to retain the nutritional values of those cheap substrates. Broad industrial perspectives can be achieved when quality as well as the quantity of the biosurfactant is considered in great depth. Since substrates resulting from food processing, dairy, animal fat industries are not explored in great details; and hence are potential areas which can be explored thoroughly.

Biosurfactants are amphiphilic compounds produced by microorganisms and have multifarious uses in industry and agriculture. The biosurfactant producing microbes are helpful in bioremediation of heavy metal, pesticides and hydrocarbon contaminated sites. They are also used as bio-control agent to protect plant against various diseases, resulting in higher crop yields. The present study was aimed to isolate potential biosurfactant producing bacteria from oil contaminated sites. Initially 37 bacteria were isolated among them nine biosurfactant produces were screened based on surface tension reduction, emulsification index, modified drop collapse test and oil displacement activity. The isolate FKOD36 was the most effective biosurfactant producer as it showed the maximum reduction in surface tension (35.15 dyne/cm) with an emulsification index of 66.7% and oil displacement activity of 3.7 mm. The bacterium was identified by using partial 16S rRNA sequencing and it belonged to genus Klebseilla, and was designated as Klebseilla sp. FKOD36. The strain was also capable of utilizing phenanthrene as the highest bacterial biomass was produced by this strain in phenanthrene amended MS media compared to other isolates. This suggests that selected strain Klebseilla sp. FKOD36 could have potential to degrade the hydrocarbon contaminated sites that could be helpful in conservation of natural resources.

“…Such properties make them good candidates for EOR (Bannat, 1995b;Bannat et al, 2000). This biological surface active compounds have several advantages over the chemical surfactant such as lower toxicity, higher degradability and better environmental compatability, higher foaming, higher selectivity and specific activity at extreme pH, temperature and salinity (Fietcher, 1992;Sullivan, 1998;Gautham and Taygi, 2006;Bodour and Miller, 2002;Gerson, 1998). In the present studies, isolation and identification of lipopeptide producing bacilli and extraction of biosurfactant were assessed.…”

ABSTARCT: Microbially produced lipopeptide have been isolated and studied for microbial enhanced oil recovery.About 60 gram positive bacteria isolated from soil contaminated with crude oil, near the crude oil storage tank in Tehran Refinery, Tehran, Iran. However, most of these studies have produced lipopeptide by one of the pure-culture microbes isolated in a laboratory. Among the isolates, heamolytic tests revealed two biosurfactant producers. The isolated strains were designated as C2, E1. By using morphological, biochemical and molecular biology tests (16 SrRNA), the strains identified as Bacillus licheniformis and Bacillus subtitlis, respectively. Emulsification activity and measurement of surface tension indicated that, the isolates were high producers of biosurfactant. The product of C2 and E1 is mainly lipopeptide. This product reduce surface tension from 65 to 30 mN/m. Emulsified activity of crude oil was 92% for C2 and 90 % in case of E1. This is the first report of indigenous Bacillus licheniformis and Bacillus subtilis from a soil contaminated with oil in an Iranian refinery with ability to produce biosurfactant.
