[Growth efficiency and the specific rate of the yeast Hansenula polymorpha during continuous cultivation on methanol].
The growth of Hansenula polymorpha DL-1 in the chemostat (under methanol limitation) and turbidostat was measured. Cultivation with different specific rates of growth mu made it possible to determine the maximum yield of biomass Ys(max)=0.425 and the level of expendables required to maintain Ms=0.023 hr-1. The following parameters describing mu as a function of the concentration of methanol S in the fermenter were found: muo=0.154 hr-1 (maximum growth rate), Ks=1.31 mg/l, Ki=5.35 g/l. The paper emphasizes a very low value of the saturation constant Ks derived from the above experiments and reviews the literature data on the kinetic characteristics of various methanol-grown yeast.
