Single cell protein production

In general, nonconventional protein foods must be competitive with conventional plant and animal protein sources on the bases of cost delivered to the consumer, nutritional value to humans or animals, functional value in foods, sensory quality, and social and cultural acceptability. Also, requirements of regulatory agencies in different countries for freedom from toxins or toxic residues in single-cell protein products, toxic glycosides in leaf protein products, pathogenic microorganisms, heavy metals and toxins in fish protein concentrates, or inhibitory or toxic peptide components in synthetic peptides must be met before new nonconventional food or feed protein products can be marketed.

Haulm (stem) The possibility of using winged bean haulm as a potential raw material for single cell protein production in the tropics has been investigated by Zomer et al. (78). Semi-sol id fermentation of haulm, using various fungi, yielded a product containing 20% true protein, a 30% increase over the native material. The fermentation also increased the sulfur amino acid content by 1.5 to 6 fold.

Methanol appears to be the preferred carbon source for single cell protein production though several hydrocarbons could be used. Bacteria is grown in a mixture of air and methanol containing ammonia, water and other mineral nutrients. An ICI... 

Continuous fermentation processes are primarily used in the research and development stage. However, more chemostat operations are being used at the production level as the understanding of this reactor increases. Examples include ethanol fermentation for the production of fuel grade ethanol and single-cell protein production from methanol substrates.

The strategy for optimizing single-cell protein production is based not only on a dilution rate that will give a low residual substrate concentration and high conversion yield, but also that will operate with the maximum cell density permitted by the oxygen transfer rate. Simultaneously, it is important to prevent accumulation of residual methanol to achieve both high yields and process stability.
