Night soil has been aerobically digested effectively and malodorlessly at Inacuo Sanitation Center facility. In 1991, microorganisms in the digestion tanks were isolated, and 92-98% of them was <I>Bacillus</I> sp. On the basis on the biochemical characteristics and GC - contents, species of 32 strains of them were identified to be <I>B. thuringiensis</I> (12 strains), <I>B. megaterium</I> (1 strain), <I>B. pumilus</I> (16 strains) and <I>B. subtilis</I> (1 strain) . Strains identified to be <I>B. thuringiensis</I> showed the solubilizable ability of starch and the usable ability of ammonia as the source of nitrogen like <I>B. megaterium</I>, while strains identified to be <I>B. pumilus</I> showed to solubilize cooked meat, and to use nitrate ion like <I>B. subtilis</I>.
