THE SCREENING OF THE STRAINS OF DISTILLER''S GRAINS TO PRODUCE FEEDING-PROTEINS
发酵白酒糟生产饲料蛋白的优良菌种的筛选

A number of strains producing feeding-proteins from distiller's grains were obtained from more than 1000 strains (include fungi, yeasts, streptomycetes and bacteria) using conventional screening methods. The experiment for single strain fermentation, various strains combination, different media composition were carried out. Under the condition of the laboratory, the content of raw protein of fermentative product reached 35.9%, it was 50% and 30% higher than the distiller's grains and the medium used respectively. 15% of the content of raw cellulose was reduced. The content of raw fat was about 5.5%. The productive rate was up to 80%. The results showed that the strains obtained are good ones to produce feeding-proteins from fermentation of distiller's grains.
