Abstract

本研究では、<i>Lactobacillus plantarum </i>ATCC 8014を用いた場合の地域の海産食品排水の処理能について解析した。初めに、滅菌排水への供試細菌の標準添加方法とpH変動や酸性度、溶存タンパク質、供試細菌の生育について分析した。その結果、供試細菌添加系ではpHの低下傾向と酸性度の上昇がみられたが、供試細菌無添加系では、酸性度の維持もしくは低下がみられた。供試細菌添加系の溶存タンパク質濃度の最大値は、供試細菌無添加系の溶存タンパク質濃度の最大値よりも先に起こった。供試細菌無添加系の細菌群のコロニー形成と供試細菌添加系の細菌群のコロニー形成を比較すると、供試細菌無添加系の方がコロニー形成能は低かった。実排水における供試細菌のコロニー形成へのpHと酸性度の影響を糖液1%と5%添加系それぞれで評価した結果、pHと酸性度の両方に対して1%添加系がよりコロニー形成に影響を及ぼされた。一方、5%添加系では、BOD除去とともに糞便大腸菌群数が効果的に減少したことが示された。

In the present study, the bacterial inoculation and colonization of marine food wastewater with inoculated<i> Lactobacillus plantarum </i>ATCC 8014 was analyzed. Firstly, an inoculation standardization procedure of the bacteria in sterile wastewater, and examined the effect of this inoculation testing for pH kinetics, acidity, soluble proteins and bacterial growth were conducted. The results demonstrate that the inoculated strains have a tendency to decrease pH and to increase acidity, whereas non-inoculated strains had a tendency to keep or decrease acidity. Soluble proteins from the inoculated strains reached a maximum peak before non-inoculated strains. Colonization growth from the non-inoculated strains had a significant higher mortality compared to the inoculated bacteria. The effect of the inoculated <i>L. plantarum</i> on the raw wastewater colonization, with inoculum percentages of 1% and 5%, both with and without molasses were investigated. The results suggested that for both pH and acidity, the most effective inoculums were at 1%, whereas 5% inoculums proved to be effective in decreasing MPN of fecal coliforms and in BOD removal.
