초록
From the soil collected from provincial area of South Korea, a microorganisms which have been shown good growth in the minimal poultry feces extract medium was isolated. Supplement of glucose to the poultry feces extract medium helped the complete uptake of soluble protein by microorganism. Uric acid in the poultry feces extract medium could be completely degraded during the microbial growth. Maximum cell growth (3.8 $\times$ 10$^{9}$ CFU/ml) obtained at 36 hours of incubation after inoculation. Uric acid was degraded faster in minimal medium than in the glucose complement medium. VFA (volatile fatty acid), which are known as major compounds of poultry feces odor, were almost removed from the minimal poultry feces extract medium. Glucose supplement to the minimal medium enhanced the growth of microbial cells. Addition of 4% of glucose and 4% of neopeptone to the minimal poultry feces extract medium helped the maximal growth of cells.
