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 cold ethanol precipitation, extensive dialysis […]

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 glucose-supplemented marine broth, and recovered […]

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

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 (0.6% w/v final concentration) yielded […]
