Abstract

Photosynthetic bacteria, strains KN 1-1, KN 2-1 and KN 2-3 were isolated from nature, and were studied for swine wastewater treatment. Growth of those photosynthetic bacteria were increased to 2~3 fold in organic-acid added medium(sodium acetate 1g, sodium propionate 1g and sodium butyrate 1g in Lascelles basal medium $1{\ell}$) than cultivation in Lascelles basal medium, and amount of bacteriochlorophyll a were increased to 1.5~2 fold. Chemical Oxygen Demand(COD) in swine wastewater using photosynthetic bacteria, strains KN 1-1, KN 2-1 and KN 2-3 were reduced 80%, 89% and 75%, respectively.

자연계로부터 3종의 광합성 세균 strain KN 1-1, KN 2-1과 KN 2-3을 분리하여 돈분 폐수 처리에 대한 연구를 수행하였다. 유기산이 첨가된 배지에서 광합성 세균의 생육은 유기산을 첨가하지 않은 경우에 비해 2~3배 증가하였으며, bacteriochlorophyll a 함량도 1.5~2배까지 증가함을 보였다. 또한 축산 농가에서 직접 채취한 돈분 폐수에 광합성 세균을 첨가하였을 때 COD 감소율은 KN 1-1인 경우 80%, KN 2-1 89%, KN 2-3 75%를 나타내었다.
