Abstract
A metabolic study has been conducted to investigate the conversion of pentachlorophenol(PCP) to water soluble metabolites in soybean and rice cell suspension cultures as well as in intact rice plants. PCP in plant cells was found to be exclusively transformed into water soluble metabolites. The relative rate of the metabolic conversion of PCP in decreasing order was soybean cultures > rice cultures > rice plants. Also observed was that, the older the cultures grown, the lower the conversion rate was. Primary water soluble metabolites isolated from both the 5 day old soybean and 8 day old rice cells were specifically hydrolyzed only by
Pentachlorophenol(PCP)가 대두(大豆) 및 벼 현탁배양(縣濁培養)과 과 수도체 중에서 수용성성분(水溶性成分)으로 전환(轉換)되는 것을 경시적으로 조사하여 다음과 같은 결과를 얻었다. 1. 현탁배양에서 처리한 PCP의 50%가 수용성 대사물로의 전환되는 시간은 대두의 경우 4시간, 벼는 48시간 이내였다. 수용성 대사물의 생성속도와 양은 PCP의 cell 생육 저해 정도와 밀접한 관계가 있었다. 2. 식물 cell에서 PCP의 주(主) 대사과정(代謝過程)은 생육시기(生育時期) 및 약제(藥劑) 처리시간(處理時間)을 달리한 전환시험에서 얻은 수용성 대사물 및 glucose cunjugates 함량변화 조사와 conjugates가 가수분해 되는 성질로부터 glucose conjugates(
