The need for protein feed and the need to dispose of waste cellulose are problems being studied to develop a feasible method for the direct conversion of cellulosic wastes to microbial protein--a single cell protein to be used as an animal feed supplement. This report presents data on the process and summarizes research in large-scale production. The economics and techniques of the conversion process are compared with work done by petroleum companies on the fermentation of hydrocarbons. Controlling variables used in the process are defined and significant goals necessary to achieve success in the field are described. The research deals mainly with the alkali treatment and fermentation parts of the process. Different micro-organisms from which single cell protein can be produced are given. Research in the areas of cell flocculation, flotation, or hyperfiltration are recommended to improve the most costly single step of the process-drying the cells. Methods of decreasing the degree of crystallinity are also included. The practicality of complete acid hydrolysis of cellulose to a soluble substrate for conversion to yeast protein and partial acid hydrolysis of the cellulose followed by microbial consumption is discussed. An economic analysis is given of the potential markets and the competitive cost with other proteins. (Modified author abstract)
