Notizen:
The microorganism Candida utilis was grown on both filtered and unfiltered substrate obtained from enzymatic hydrolysis of starch in corn dust. For growth on filtered substrate, the average integrated biomass energetic yield value based on biomass-substrate data was η = 0.55 and for growth on unfiltered substrate an average yield value of η = 0.59 was obtained. Material and energy balances showed that the presence of unfiltered corn residue in the media had no significant effect on the yields. Statistical methods were developed and used to obtain best estimates of the growth parameters. Values of the biomass energetic yield corrected for maintenance (ηmax = 0.619) and the maintenance coefficient (me = 0.043) were obtained for growth on filtered substrate. Values of ηmax = 0.741 and me = 0.142 were obtained for the growth on unfiltered substrate. The consistency of data and parameter estimates was relatively good for filtered substrate; however, parameter estimates for unfiltered substrate were not consistent. Growth experiments without filtration of the products of starch hydrolysis resulted in protein-enriched products with about 39.73% protein.
