Microbial single-cell oils

To parallel the term SCP (single cell protein), the term single cell oil (SCO) was coined (Ratledge, 1976) and this continues to be used as a slight euphemism for microbial oils (Moreton, 1988a Kyle and Ratledge, 1992).

Whey permeate may also be fermented anaerobically to fuel gas. Studies have also been reported on the production of ammonium lactate by continuous fermentation of deproteinized whey to lactic acid followed by neutralization with ammonia. Conversion of whey and whey permeate to oil and single-cell protein with strains of Candida curvata and Trichosporon cutaneum have been examined. Production of the solvents n-butanol and acetone by Clostridium acetobutylicum or C. butyricum is under investigation in New Zealand. Whey permeate also has potential for citric acid and acrylic acid manufacture. Extracellular microbial polysaccharide production from whey permeate has...
