Biosurfactants are the surface active compounds produced by micro-organisms. The eco-friendly and biodegradable nature of biosurfactants makes their usage more advantageous over chemical surfactants. Biosurfactants encompass the properties of dropping surface tension, stabilizing emulsions, promoting foaming and are usually non- toxic and biodegradable. Biosurfactants offer advantages over their synthetic counterparts in many applications ranging from environmental, food, and biomedical, cosmetic and pharmaceutical industries. The important environmental applications of biosurfactants include bioremediation and dispersion of oil spills, enhanced oil recovery and transfer of crude oil. The emphasis of present review shall be with reference to the commercial production, current developments and future perspectives of a variety of approaches of biosurfactant production from the micro-organisms isolated from various oil- contaminated sites and from the by-products of oleo-chemical industry wastes/ by-products viz. used edible oil, industrial residues, acid oil, deodorizer distillate, soap-stock etc.

We discovered that Candida floricola ZM1502 is capable of selectively producing the promising hydrophilic biosurfactants, acid-form sophorolipids (SLs), from glycerol. However, productivity was very low (approximately 3.5 g L) under the initial culture conditions.

Biosurfactants (BSs) are produced in abundance from various feedstocks by diverse microorganisms, and are used in various applications. In this paper, we describe a new yeast isolate that produces glycolipid-BSs from glycerol, with the aim of enhancing the utilization of the surplus glycerol produced by the oleo-chemical industry. As a result of the screening, strain ZM1502 was obtained as a potential producer of BS from glycerol.

Unlabelled: A total of 33 Lactobacillus strains were screened for feruloyl esterase (FE) activity using agar plates containing ethyl ferulate as the sole carbon source, and Lactobacillus fermentum NRRL B-1932 demonstrated the strongest FE activity among a dozen species showing a clearing zone on the opaque plate containing ethyl ferulate. FE activities were monitored using high-performance liquid chromatography with an acetonitrile-trifluoroacetic acid gradient. To produce sufficient purified FE from L.

Fats or oils are split partially or completely to obtain fatty acids that find wide applications in oleo-chemical industries. Lipase-mediated complete splitting (hydrolysis) of oils is a green process having great potential to replace the traditional methods of oil splitting. However, cost of lipases, mechanistic kinetic equilibrium and associated operational limitations prove to be deterrents for scale up of the enzymatic oil splitting process.

Background: Oleaginous microorganisms, such as bacterium, yeast and algal species, can represent an alternative oil source for biodiesel production. The composition of their accumulated lipid is similar to the lipid of an oleaginous plant with a predominance of unsaturated fatty acid. Moreover this alternative to conventional biodiesel production does not create competition for land use between food and oleo-chemical industry supplies.
