Potatoes protein liquor

Potato pulp and potato pulp residue (after acidic treatment) and nutrient salt solution and potato protein liquor, respectively, were used for the production of cellulases and hemicellulases by Trichoderma reesei Rut C30 in a continuously operated bioreactor, (Klingspohn and Schiigerl... 

Saccharomyces cerevisiae was cultivated with potato protein liquor (PPL) and glucose (starch hydrolysate) as substrate. Before the start of the cultivation PPL was sterilized at various temperatures between 80 and 120 °C for different periods between 5 s and 30 min [27]. The foaminess of PPL was very low before the sterilization. The foaminess increased with the temperature and time during sterilization and, at 120 °C and 30 min, 2 was enlarged by a factor of 2x10. This effect is due to the denaturation of proteins [4] and the formation of Maillard reactions between reducing sugars and amino adds [28]. 

Peki lo process Abiochemical process developed in Finland for the production of singlecell protein using a fungal biomass. It uses various forms of carbohydrates as the substrate including spent sulphite liquors from the wood and paper industries as well as waste liquors from the potato and sugar industries.
