Abstract

Six bacteria, which showed the flocculating activity to food wastewater, were isolated from various environment. These strains were identified as Bacillus pumilus, Enterobacter sp., Pantotea agglomerans, Bacillus licheniformis, and two Bacillus sps. Among them, the flocculating activities of three strains, such as Enterobacter sp.(YK102), Bacillus sp.(YK103), and Pantotea agglomerans (YK104), were eight times or more higher than that of the control strain, Zoogloea ramigera. in the test with 0.5% kaolin. In the experiment with food wastewater, Enterobacter sp.(YK102) showed the highest flocculating activity which was 2.5 times higher than that of a control strain, Pseudomonas fluorescens.

다양한 환경으로부터 음식물류폐수에 응집특성을 보이는 미생물 6종을 분리하였다. 동정한 결과, 이들은 각각 Bacillus pumilus, Enterobacter sp., Pantotea agglomerans, Bacillus licheniformis, 그리고 두 종류의 Bacillus sp. 균주들로 밝혀졌다. 분리된 미생물중 Enterobacter sp.(YK102), Bacillus sp.(YK103), Pantotea agglomerans (YK104) 등, 3균주의 경우, 대조군으로 사용된 분양균주 Zoogloea ramigera와 비교하여 카올린에 대한 응집율이 모두 8배 이상 높은 것으로 나타났다. 음식물류폐수에 대한 응집실험에서는 Enterobacter sp.(YK102) 균주가 가장 높은 응집능을 보였으며, 대조군으로 사용된 Pseudomonas fluorescens보다 약 2.5배 높은 것으로 나타났다.
