Notes:
The methanol-utilizing yeast Hansenula polymorpha MH 26 is thermotolerant and grows at 40°C and pH 3.5 with a maximum specific growth rate of 0.23 h-1 on methanol.In continuous cultivation the maximum cell yield can be improved of 0.35 (methanol) to 0.44 g dry cells/g methanol (mixtures of methanol and stillage) through additional utilization of the essential growth and nutritive substances of stillage.The utilization of methanol and sucrose (molasses) at various mixtures is simultaneous possible. Investigations of these mixtures with 14C-marked methanol show an increasing incorporation of methanol of about 20-30% against methanol alone. This effect is caused by the increasing metabolization of sucrose to carbondioxide and additional energy delivery for better assimilation of methanol.
