Selection of a yeast strain with optimal utilization of straw hydrolyzates.
The dry nonseparated straw hydrolyzates prepared by mild acid hydrolysis of milled straw contains 25--30% of reducing substances, mostly saccharides with prevalence of xylose. A strain utilizing the neutralized nonseparated hydrolyzates without any growth substances added was obtained by selection and long-term adaptation of an array of yeast strains. The strain, identified as Candida tropicalis 2838, exhibited high cell-growth rate and considerable yield of protein-rich biomass.
