Biosurfactant: Pharmaceutical Perspective
Surfactants are amphipathic compounds having both lipophilic and hydrophilic structural moieties in its molecule. They are mostly produced on microbial surfaces or excreted extracellular hydrophobic and hydrophilic moieties. Due to such nature, solubility of hydrophilic molecules is increased alongwith reductions in surface and interfacial tensions at the oil/ water interface [1]. Surfactants a...
متن کاملPseudomonas Rhamnolipid Surfactant (Biosurfactant)
A microbial surfactant (biosurfactant) was investigated for its potential to enhance bioavailability and, hence, the biodegradation of octadecane. The rhamnolipid biosurfactant used in this study was extracted from culture supernatants after growth of Pseudomonas aeruginosa ATCC 9027 in phosphate-limited proteose peptone-glucose-ammonium salts medium. Dispersion of octadecane in aqueous solutio...
متن کاملIntegrated systems for biosurfactant synthesis
Biosurfactants are difficult to produce in an economic manner for several reasons: 1. Overproducing strains of bacteria are rare and those found generally display a very low productivity. In addition complex media need to be applied. 2. The regulation of biosurfactant synthesis is hardly understood, seemingly it represents a "secondary metabolite" regulation. Among others 02-limitation has been...
متن کاملBiosurfactant production by Myrciaguianensisendophytic fungi
Surfactants are amphipathic molecules constituted by hydrophobic and hydrophilic regions that usually get distributed on interfaces between fluid phases of different polarities (water/oil and oil/water) [1]. Several compounds with tensoactive properties are synthetized by living organisms (animals, plants and microorganisms), being considered natural surfactants or biosurfactants, which reduce ...
متن کاملReplacement of hexachlorocyclohexane to environmentally friendly biosurfactant as precursor for the production of biosurfactant from Pseudomonas.
Production of biosurfactant can be substantially increased by the addition of precursors like vegetable oils, petroleum products, and other water-insoluble substances. Pseudomonas Ptm+ strain produces biosurfactant in the presence of hexachlorocyclohexane (HCH), which specifically emulsifies HCH, a recalcitrant organochlorine pesticide. Addition of previously produced crude biosurfactant by the...
