Abstract

A series of yeast strains utilizing methanol as the only source of carbon and energy were isolated both from soil and waste waters. Growth of the yeasts was studied in a mineral medium with yeast extract at 30°C. Growth parameters, Qo 2 and composition of biomass were studied in the strain 11Bh producing in shaken flasks highest yields of biomass. The biomass was found to contain 44% of crude proteins, 2% esterified fatty acids, 3% non-esterified fatty acids, 6% RNA and 0.25% DNA. Amino acid analysis revealed a high content of essential amino acids, lysine, leucine, valine and threonine in particular.
