Abstract

When minced model kitchen refuse was inoculated with Bacillus coagulans and incubated under non-sterilizing open condition, at the temperature below 45°C, racemic mixture of D-and L-lactic acid was found, while L-lactic acid was selectively accumulated at 50-65°C. To analyze microflora of such mixed culture system, whole cells (fluorescent in situ hybridization) using species and group of specific 16S rRNA-targeted oligonucleotide probes (16S-FISH) was applied. As a result, predominancy of mesophilic lactic acid bacteria at lower temperature, and of Bacillus coagulans at higher temperature was confirmed.
