Exopolysaccharides produced by Gordonia alkanivorans enhance bacterial degradation activity for diesel

Enzymatic modifications of exopolysaccharides enhance bacterial persistence

Biofilms are surface-attached communities of bacterial cells embedded in a self-produced matrix that are found ubiquitously in nature. The biofilm matrix is composed of various extracellular polymeric substances, which confer advantages to the encapsulated bacteria by protecting them from eradication. The matrix composition varies between species and is dependent on the environmental niche that...

Cholesterol degradation by Gordonia cholesterolivorans.

This paper reports physiological and genetic data about the type strain Gordonia cholesterolivorans, a strain that is able to degrade steroid compounds containing a long carbon side chain such as cholesterol (C(27)), cholestenone (C(27)), ergosterol (C(28)), and stigmasterol (C(29)). The length of the carbon side chain appears to be of great importance for this bacterium, as the strain is unabl...

Sterilization of Exopolysaccharides Produced by Deep-Sea Bacteria: Impact on Their Stability and Degradation

Polysaccharides are highly heat-sensitive macromolecules, so high temperature treatments are greatly destructive and cause considerable damage, such as a great decrease in both viscosity and molecular weight of the polymer. The technical feasibility of the production of exopolysaccharides by deep-sea bacteria Vibrio diabolicus and Alteromonas infernus was previously demonstrated using a bioprod...

Draft Genome Sequence of Gordonia alkanivorans Strain CGMCC6845, a Halotolerant Hydrocarbon-Degrading Bacterium

Gordonia alkanivorans strain CGMCC6845 is a halotolerant hydrocarbon-degrading bacterium isolated from petroleum-contaminated saline soil. Here we present the 5.0-Mb draft genome sequence of this strain, which will improve our understanding of the diversity of G. alkanivorans and the mechanisms of microbial hydrocarbon degradation in saline environment.
