Summary With bacterial association MS1 grown on methanol in a chemostat at various dilution rates (0.24–0.48 h−1) and different temperatures (34–41.6°C), we determined the biomass X, the substrate yield YS, the productivity DX, and we also analyzed the cell composition. A maximum yield of 0.44 g cell/g CH3OH and a maximum productivity of 4.55 g/l/h were found for a growth temperature of 34°C. The specific maintenance coefficient m was measured and was found to decrease with decrease in temperature. We also showed that YS as well as the ratio of total nucleic acids to proteins increase with the dilution rate at constant temperature and decrease when the growth temperature rises at constant dilution rate. At the same time, the crude protein content (N×6.25 max=78.6%) and the amino acid composition showed that mixed MS1 culture is feasible as a protein source for animal feed.
