摘要:Yeast Trichosporon cutaneum isolated from the whey has been cultivated on the rotary shaker and batch-wise or continuousely in the laboratory bio-reactor. Yeast T. cutaneum growed well at all studied concentrations of lactose in substrate, but the highest productivity of the process was achieved with 0,48-0,60 g DM/g lactose with the specific growth rate of 0,26 h^-1 and the productivity of 1,5 g/dm3/h.
