Production conditions of bacterial protein feeds by solid-state fermentation of potato residue

The potato pulp waste were used as raw material to produce bacterial protein feeds.

The effects of water content and nutrient salt on solid ethanol fermentation of sweet sorghum stalk were studied and the feasibility of the joint production of protein feedstuff was also demonstrated.

From one ton of the wastewater 5 kg protein feedstuff could be extracted.

The results show that the solid-state fermentation of herb residues by Trichoderma koningii to produce protein feedstuff is feasible.

Studies on feed protein production from apple pomace by liquid-solid state fermentation;

The suitable mutant strains for producing feed protein from apple pomace were breeded through mutagenesis to Cider utilis and Trichoderma reesi with a self-made semiconductor-laser.

The paper describes the significance, industry situation and production method of SCP from methanol as a feed protein,and points out the development prospect of SCP from methanol.

A study of feeding protein inverted from brewer's grains by biological method;

This process take the penicillin residue as cultural media,it can hydrolysis protein into phthalein and amino acid,through further process,make yeast,and the solid residue can make feeding protein.

The objective are research for technics conditions of ferment distille's grains to produce feeding protein,and supported on technics for industrialisation.

The fermentation of fresh pomace producing feeding-protein;

Breeding strains for producing feeding-protein in fermentation of apple pomace;

The suitable 24 strains were obtained for producing feeding-protein from distillers' grains by conventional methods.
