Construction of an Efficient Mutant Strain of Trichosporonoides oedocephalis with HOG1 Gene Deletion for Production of Erythritol.

The mitogen-activated protein kinase HOG1 (high-osmolarity glycerol response pathway) plays a crucial role in the response of yeast to hyperosmotic shock. Trichosporonoides oedocephalis produces large amounts of polyols (,e.g., erythritol and glycerol) in a culture medium. However, the effects of HOG1 gene knockout and environmental stress on the production of these polyols have not yet been st...

In Vitro Fermentation of Galactosyl Derivatives of Polyols by Lactobacillus Strains

Klewicka E., Klewicki R. (2009): In vitro fermentation of galactosyl derivatives of polyols by Lactobacillus strains. Czech J. Food Sci., 27: 65–70. Probiotic lactic acid bacteria belonging to the species Lactobacillus casei, Lb. paracasei, and Lb. acidophilus were cultivated in the presence of galactosyl derivatives of erythritol, xylitol, and sorbitol, as well as the polyols themselves: eryth...

Polyol accumulation by Aspergillus oryzae at low water activity in solid-state fermentation.

Polyol accumulation and metabolism were examined in Aspergillus oryzae cultured on whole wheat grains or on wheat dough as a model for solid-state culture. In solid-state fermentation (SSF), water activity (a(w)) is typically low resulting in osmotic stress. In addition to a high level of mannitol, which is always present in the cells, A. oryzae accumulated high concentrations of glycerol, eryt...
