| Research Abstract |
About 7,200 colonies of halo-alkaliphilic bacteria were isolated from the samples collected from 4 sources including Lake Nakaumi in Shimane Prefecture. 127 colonies with high decomposition ability of organic compounds were selected by second screening. All bacteria isolated belong to the genus Bacillus. After alkalinized the sludge by the addition of CaO, selected strains were added to the sludge and decomposition of organic compound were examined. As a result of the incubation, we found that elution of phosphate was decreased sharply and about 20% of organic carbon was decreased.
