Production of single‐cell protein with cellulomonas sp. on hempstalk wastes

Strains of Cellulomonas isolated from enrichment cultures with cellulose powder were cultivated with hempstalk wastes as the sole carbon source in a mineral medium. The yields of protein were not significantly different using the crude or alkali pretreated substrate in flasks experiments. Up to 12.5% protein was obtained on the untreated substrate with the best strain cultivated in a small fermenter.
