Abstract
Six kinds of lactic-acid forming bacteria were isolated from an environmental preservation material (Ehime AI) and fermented and matured sediment mud from Osaka Bay. Among these isolated bacteria, strain Ob from Osaka Bay showed the highest COD removal of sediment mud (30.4% reduction) after 4 weeks. Strain Aa from Ehime AI showed 13.8% COD removal as the highest active strain of lactic acid formation. High lactic-acid forming ability of bacteria was not correlated to high COD reduction. Strain Ob was identified as Paenibacillus motobuensis using genetic analysis.
