To find a new processing technology for microbial treatment of food production waste, experiments were performed to obtain a thermophilic flora derived the bacteria isolated from panda feces and the use of the high temperature-adapted flora for treating waste such as wheat bran and/or tofu residues was investigated. Using commercial waste-treatment devices, a total of 79.7kg of mixed refuse consisting of tofu-residue and fish was treated for 17 weeks, 67.2kg of wheat bran and fish refuse was treated for 12 weeks and 100.2kg of wheat bran, tofu-residue and fish was treated for 17 weeks, resulting in final digestive rates of 95.12%, 95.24% and 97.01%. The internal temperature of the compost mass reached peaks of 73.2C[Celsius degree], 72.8C[Celsius degree] and 72.4C[Celsius degree], respectively. These results indicate that the bacterial flora may be useful for waste treatment of food production refuse at a high performance rate at high temperatures.
Key words: wheat bran, tofu residues, bacterial-treatment, themophilic bacteria, bacteria from panda feces
