The fermentation of cellulosic wastes by cellulolytic bacteria shows promise as a process for obtaining new low-cost protein sources; at the same time, it solves a problem of waste disposal. At present, many problems remain to be solved before making this process economically profitable. The low productivity due to poor cell density attained, and low nutritive value of the biomass produced stand out as two of them. Humphrey et al. have pointed out that the critical question in the microbial degradation of cellulose is how to optimize the cell yield in order to achieve nearly total cellulose degradation. Belamy calculated that the rate of cellulose utilization should be at least 1-5 g/l/h for the process to be profitable. The work described here deals with how increases of cell concentration and productivity change the media concentration of a fermentation process using Cellulomonas sp., and the determination of the nutritive value of the product. (Refs. 12).
