Production of single cell protein from agricultural and food processing wastes

Abstract A process has been developed in which carbohydrate wastes are fermented to produce microbial protein suitable for animal feeds. The process consists of (i) a waste preparation step, (ii) growth of a filamentous mould in submerged culture at a low pH (iii) recovery of the mould by filtration (iv) drying and bagging. It is estimated that operating scales as low as five hundred tons/annum can be made economic if the process can be used for most of the year and labour costs are low.
