Agricultural and Food Processing Wastes as Potential Substrates in Microbial Protein Production: Chemical Analysis

  • R. G. Lorica

A number of agricultural and food processing wastes were analyzed in order to determine their potential as substrates for microbial cell production. Potential was evaluated in terms of the following parameters: % crude protein, % neutral detergent fiber, % cellulose, % crude fat, % lignin, and gross energy value. The high lignin content of a good number of these materials indicates that the lignocellulose complex may have to be broken down in a chemical step before these can effectively function as a carbon source during the fermentation process leading to the production of microbial proteins.
