We have isolated the cytosolic form of Cu-Zn superoxide dismutase (SOD) from the marine yeast Debaryomyces hansenii. This enzyme has a subunit mass of 18 kDa. The preparation was found to be heterogeneous by IF electrophoresis with two pI ranges: 5.14-4.0 and 1.6-1.8. The enzyme preparation had a remarkably strong stability at pH 6.0-7.0, surviving boiling for 10 min without losing more than 60...

The inoculation of a Debaryomyces hansenii strain in dry fermented sausages with reduced fat and salt contents was evaluated in terms of chemical, microbial and consumer acceptability. The implantation of the inoculated yeast strain was confirmed by RAPDs of M13 minisatellite. A reduction of 17e20% salt and 10e16% fat content was achieved. These reductions affected the sausage quality by produc...

BC membranes (pellicles) generated by Gluconacetobacter hansenii (G. hansenii) are promising biomaterials owing to their outstanding biocompatible properties. Recently, specific demands for biomedical applications of have increased its excellent mechanical Although many techniques been developed improve the biofunctional properties pellicles, such modifications remain limited technical difficul...

BACKGROUND Oleaginous yeast species are an alternative for the production of lipids or triacylglycerides (TAGs). These yeasts are usually non-pathogenic and able to store TAGs ranging from 20 % to 70 % of their cell mass depending on culture conditions. TAGs originating from oleaginous yeasts can be used as the so-called second generation biofuels, which are based on non-food competing "waste c...

Los probióticos son bichos diminutos cuyo consumo genera efectos benéficos en la salud. De hecho, palabra probiótico significa 'pro-vida'. Algunas levaduras, como utilizada para hacer pan o cerveza, pueden ser animales y humanos. Desde hace algunos años, los estudios con levadura Debaryomyces hansenii han demostrado que ésta es un probiótico. Se ha que, administrada por vía oral, esta tiene est...

Phenolic compounds are natural substances that can be obtained from plants. Many of them potent growth inhibitors foodborne pathogenic microorganisms, however, phenolic activities against spoilage yeasts rarely studied. In this study, planktonic and biofilm growth, the adhesion capacity Pichia anomala, Saccharomyces cerevisiae, Schizosaccharomyces pombe Debaryomyces hansenii were investigated i...

This study reports the release of the complete nucleotide sequence of Gluconacetobacter hansenii strain NQ5 (ATCC 53582). This strain was isolated by R. Malcolm Brown, Jr. in a sugar mill in North Queensland, Australia, and is an efficient producer of bacterial cellulose. The elucidation of the genome will contribute to the study of the molecular mechanisms necessary for cellulose biosynthesis.

Twenty-six yeasts from different genera were investigated for their ability to metabolize biogenic amines. About half of the yeast strains produced one or more different biogenic amines, but some strains of Debaryomyces hansenii and Yarrowia lipolytica were also able to degrade such compounds. The most effective strain D. hanseniii H525 metabolized a broad spectrum of biogenic amines by growing...
