폐기배추가 분해될 때 토양층에서 그람 양성 및 음성균 군집이 발달되어 pH는 4.5까지 전환되었고, 동시에 폐기배추의 부패가 6일동안 관찰 되었다. 폐기여액에서 두 종류의 세균 군집의 계속적인 생장에 의하여 pH는 약 8.5까지 도달 하였으며 그 후, 조류의 번식이 시작되었다. 세균 군집중 우점종은 토양층에서 Erwinia cypripedii, Lactobadllus farciminis와 폭기된 폐기여액에서 Erwinia salis, Bacillus coagulans, B. cereus, B. subtilis이었다. 우점조류는 Scenedesmus dimorphus로 동정 되었다. 조류의 최적 배양조건 중 광도, pH 그리고 폭기량은 각각 16 Lux, 9.0, 4 LPM이었다. 폭기 폐액여액내의 조류의 성장으로 인과 질소는 각각 81%와 61% 정도로 제거 되었다.

Attempts were made to study microbial community dynamics in the biodegradation of waste cabbage recovered from Kimchi preparations on the soil-bed and waste filtrates obtained from the degraded cabbages. On the soil-bed, Gram positive and Gram negative bacterial communities developed and transformed pH to 4.5, and the concurrent putrefaction of waste cabbages were observed for 6 days. In waste filtrates, pH reached 8.5 by the continuous growth of bacterial communities and thereafter algae started the growth. In bacterial communities, dominant species were Erwinia cypripedii, Lactobadllus farciminis and L. fructosus in the soil-bed, and Erwinia salis, Bacillus coagulans, B. cereus and B. subtilis in the aerated waste filtrates. Dominant algae was identified as Scenedesmus dimorphus. The optimal culture conditions of algae were that illumination density, pH and amount of aeration were 16 Lux, 9, and 4 litre per minute, respectively. Through the algal growth in aerated waste filtrates, phosphorus and nitrogen were removed by about 81% and 60%, respectively.
