The strains of clostridia were isolated from representative colonies obtained from poor silages. The strains, No. 1 and No. 31, No. 4 and No. 27, No. 3 and No. 5, and No. 32 were assumed to be Cl. tyrobutyricum, Cl. scatologenes, Cl. septicum, Cl. subterminale and Cl. butyricum, respectively. Effects of incubation temperatures on growth and metabolism of Cl. butyricum, Cl. scatologenes, Cl. tyrobutyricum and Cl. subterminale obtained above were examined with the anaerobic silage extract media. Each incubation of Cl. butyricum, Cl. scatologenes and Cl. tyrobutyricum at 20℃ resulted in slower increases in total VFA, butyric acid and VBN/Total-N contents of cultures and in slower decreases in lactic acid and WSC contents of cultures than that at 30℃ or 40℃. Incubation of Cl. subterminale at 20℃, 30℃ and 40℃ also caused increases in total VFA, butyric acid and VBN/Total-N contents of cultures and decreases in lactic acid and WSC contents of cultures, but consistent effects of incubation temperatures on these contents were not observed. At all incubation temperatures, pHs of the cultures showed rapid increases in inoculations of Cl. scatologenes and Cl. tyrobutyricum, but little change in inoculations of Cl. butyricum and Cl. subterminale. These results suggest that the incubation at 20℃ or lower temperature has a suppressive effect on growth and metabolism of clostridia and results in a delayed reduction in silage quality.
