The populations of microorganisms adhered on rice straws which had been ricked in the fields around Chungchong areas during the winter season from February to March in 1998 were investigated. The number of mesophilic bacteria including bacilli was generally high in the middle part of straw. And it appeared to be higher in the samples from rural areas than those from suburb. Thermophilic bacteria and actinomycetes were rarely to be detected in most samples. Coliform bacteria were detected in a few samples which collected from Kwanpyong-dong of Taejon-city, Jangpyong-meun and Jungsan-meun of Chongyang-koon, indicating that these areas were contaminated by sewage and livestock wastes. Following the fermentation of Chungkukgang employed the middle parts of straws from Mok-meun of Chongyang-koon as a source of microbial inoculum, qualities of the fermented products such as amino-nitrogen content, viscosity and protease activity, were examined: the application of rice straws resulted in better qualities of the fermented products when compared to the control, however the methods of application appeared to have little or no effect on the quality.
