Saccharomycopsis fibuligera and its applications in biotechnology

Saccharomycopsis fibuligera is found to actively accumulate trehalose from starch and the gene responsible for biosynthesis of trehalose has been cloned and its expression has been characterized. This yeast is also found to secrete a large amount of annylases, acid protease and beta-glucosidase which have highly potential applications in fermentation industry. The genes encoding annylases, acid protease and beta-glucosidase in S. fibuligera have been cloned and characterized. It is also used to produce ethanol from starch, especially cassava starch by co-cultures of Saccharomyces cereviase or Zymomonas mobilis. (c) 2009 Elsevier Inc. All rights reserved.
