Role of Bacterial Exopolysaccharides (EPS) in the Fate of the Oil Released during the Deepwater Horizon Oil Spill
Authors
Tony Gutierrez, David Berry, Tingting Yang, Sara Mishamandani, Luke McKay, Andreas Teske, Michael D. Aitken
Abstract
Halomonas species are recognized for producing exopolysaccharides (EPS) exhibiting amphiphilic properties that allow these macromolecules to interface with hydrophobic substrates, such as hydrocarbons. There remains a paucity of knowledge, however, on the potential of […]
Emulsifying properties of a glycoprotein extract produced by a marine Flexibacter species strain TG382
Authors
Tony Gutiérreza, Vincent V. Leob, Graeme M.Walkerb, David H. Green
Abstract
We report, for the first time, on the production of an emulsifying polymer produced by a Flexibacter species (designated strain TG382). This polymer, E-382,was produced extracellularly during growth of the organism in a marine broth amended with glucose. After […]
Glycoprotein emulsifiers from two marine Halomonas species: chemical and physical characterization
Authors
T. Gutierrez, B. Mulloy, K. Black and D. H. Green
Abstract
Aims: To partially purify and characterize bioemulsifiers produced by two new marine Halomonas species, TG39 and TG67, and to compare their emulsifying activities with those of commercial emulsifiers. Methods and Results: The production of emulsifiers HE39 and HE67 was achieved from […]
Microbial Biosurfactants as Additives for Food Industries
Authors
Jenyffer Medeiros Campos, Tania Lucia Montenegro Stamford, Leonie Asfora Sarubbo, Juliana Moura de Luna, Raquel Diniz Rufino, Ibrahim M. Banat
Abstract
Microbial biosurfactants with high ability to reduce surface and interfacial surface tension and conferring important properties such as emulsification, detergency, solubilization, lubrication and phase dispersion have a wide range of potential […]
Les biosurfactants, plus que jamais sollicités
Author
Ibrahim M. Banat
Abstract
Les recherches sur les surfactants, agents utilisés comme émulsifiants ou dispersants, sont stimulées par les préoccupations écologiques. De nombreux microorganismes producteurs de surfactants biodégradables pourraient permettre, à l’ avenir, de mieux lutter contre les pollutions.
