Potential commercial applications of microbial surfactants
Authors
I. M. Banat á R. S. Makkar á S. S. Cameotra
Abstract
Surfactants are surface-active compounds capable of reducing surface and interfacial tension at the interfaces between liquids, solids and gases, thereby al- lowing them to mix or disperse readily as emulsions in water or other liquids. The enormous market demand for […]

Abstract
Microorganisms synthesise a wide range of surface-active compounds (SAC), generally called biosurfactants. These compounds are mainly classified according to their molecular weight, physico-chemical properties and […]
Isolation of glycoprotein bioemulsifiers produced by marine bacteria. In Hydrocarbon and Lipid Microbiology Protocols, Springer Protocols Handbooks, Eds. McGenity et al. DOI 10.1007/8623_2014_1, Springer-Verlag Berlin Heidelberg. (In press)

Abstract
High-molecular-weight (HMW) surface-active agents (biosurfactants and bioemulsifiers) are produced by many different types of bacteria and comprise proteins, glycoproteins, lipoproteins, polysaccharides, lipopolysaccharides or complexes containing any combination of these structural types. The attraction of HMW glycoprotein bioemulsifiers as ingredients in food and drink […]

Yield and Physicochemical Properties of EPS From Halomonas sp. Strain TG39 Identifies a Role for Protein and Anionic Residues (Sulfate and Phosphate) in Emulsification of n-Hexadecane
Authors
Tony Gutierrez, Gordon Morris, David H. Green
Abstract
In this study, we investigated the yield and physicochemical properties of the high molecular weight extracellular polymeric substance (HMW–EPS) produced by Halomonas sp. strain TG39 when grown on different types and ratios of substrates. Glucose (1% w/v) and a peptone/yeast extract ratio of 5.1 […]
Emulsifying and Metal Ion Binding Activity of a Glycoprotein Exopolymer Produced by Pseudoalteromonas sp. Strain TG12
Authors
Tony Gutierrez, Tracy Shimmield, Cheryl Haidon, Kenny Black, and David H. Green
Abstract
In this study, we describe the isolation and characterization of a new exopolymer that exhibits high emulsifying activities against a range of oil substrates and demonstrates a differential capacity to desorb various mono-, di-, and trivalent metal species from […]
