The highest level of thermophilic bacterial activity was observed at 54^oC. Following an increase in temperature to 63^oC, a reduction in bacterial diversity was observed. At 66^oC, bacterial diversity increased again, and diverse bacteria including Thermus spp. and thermophilic Bacillus spp. appeared to adapt to the higher temperature. At 70^oC, bacterial activity measured as superoxide dismutase and catalase activity was significantly higher than at 66^oC. However, the decomposition rate of protein in the compost was lower than the rate at 66^oC due to the higher compost temperature. |
