Abstract
A filamentous fungus, Penicillium cyclopium, capable of growing on deproteinized whey was isolated and characterized for the purpose of production of microbial protein. This organism has a maximum specific growth rate of 0.2/hour at pH 3.0 to 4.5 and 28 degrees C in a medium containing only ammonium nitrogen and deproteinized whey. The yield coefficients are 0.68 g biomass/g lactose, 12.0 g biomass/g nitrogen, and 2.10 g biomass/g oxygen respectively. Crude protein and total nucleic acid contents of this organism are 47.5% and 7.4% (dry cell weight basis), respectively. The profile of essential amino acids show that it could be a good source of animal feed or food protein. However there are several advantages in using fungal cells (Spicer 1971); their amino acid profile is better, the recovery of biomass from the culture broth is much easier, their filamentous structure facilitates production of texturized foodstuffs without extraction and spinning, and they are already accepted as foods in many parts of the world. The authors have selected a filamentous fungus, Penicillium cyclopium which grows fast on deproteinized whey and has a high protein content. This paper describes the quantitative physiology of this organism and the amino acid profile of its protein.
