methodsS. cerevisiae strain 14 used in this work was received from thecollection of the Laboratory of Cell Biology, Institute of Microbiol-ogy and Biotechnology, University of Latvia. Yeast strain S. cerevisiaeTS1 was received from the collection of the University of Aber-tay, Dundee, Scotland, UK. Yeast cultures were grown on nutrientmedia containing (g L−1): molasses, 20; (NH4)2SO4, 3.7; MgSO4,0.75; NaCl, 0.5; KH2PO4, 1.0; K2HPO4, 0.13; pH 5.0 in flasks withtotal volume 250 mL in an orbital shaker (140 rpm) at 30◦C or at37◦C.Biomass dehydration was performed by a convective methodin an oven at 30◦C for 24 h.
