We studied the effect of fermented sake (moromi)solutions and sake cake extracts on the growth of cancer cells. The long fermented moromi solutions inhibited the growth of cancer cells. On SDS/PAGE (sodium dodecyl sulfate/polyacrylamide gel electrophoresis), we found that decreasing of 52-kDa and 28-kDa protein bands in long fermented solutions. The 28-kDa protein may play an important role in the inhibition of cancer cell growth by fermented sake solutions.

Bactrerium inhabiting in Amarume crude oil of Yamagata prefecture was identified as <i>Pseudomonas mendocina</i>. In the first step, biodegradation experiments were conducted by using the bacteria of 0.510⁶ cells / ml and 300 ppm of chlorobenzene in aqueous solution under aeration and irradiation. After 6 hours, chlorobenzene was perfectly decomposed. Next, the mixtures of synthesized polychlorinated dibenzo-<i>p</i>-dioxins (PCDDs) and dibenzofurans (PCDFs) were degraded with the bacteria of 0.510⁸ cells / ml, where the initial total concentrations of PCDDs and PCDFs were 1,400 ppm and 180 μg-TEQ / ml. After 24 hours, about 70 % of PCDDs and 60 % of PCDFs were biodegraded. The biodegradation rates of PCDD / Fs were much faster than those reported in literatures with other bacteria.<br>
