Culture media contg. vegetable matter and peat hydrolysates - for high biomass yield cultivation of fodder yeasts

摘要

Culture medium contains (by wt.) 48-97% hydrolysate of vegetable matter at pH 4-4.4; 0.1-50% peat hydrolysate at pH 4-4.4; 0.02-0.08% (as N) of N source; 0.03-0.12% (as P2O5) of P source; 0.16-0.64% (as K) of K source; and water to 100%. The medium is used for cultivation of fodder yeasts that act as vitamin-protein additives to low protein basic fodder for animals and birds. The yield of the biomass of fodder yeasts is improved (up to 70 wt. %).
