Abstract
The biodegradation of ring-14C- and methyl-14C-labeled paraquat by the soil yeast Lipomyces starkeyi was studied in vitro. It was found that the degradation of paraquat (acting as a sole source of culture nitrogen) resulted in the accumulation in the extracellular medium of radiolabeled acetic acid. The culture also evolved radiolabeled CO2. The results suggest that the degradation of paraquat by L. starkeyi is associated with the integrity of the cell wall and that disruption or removal of the wall results in a complete loss of degradative capability. A mechanism for the degradation of paraquat by this organism is postulated.
摘要
在体外研究了土壤酵母斯达基酵母对环 - 14C 和甲基 - 14C 标记百草枯的生物降解。发现百草枯（作为培养氮的唯一来源）的降解导致放射性标记的乙酸在细胞外培养基中积累。培养物还释放出放射性标记的二氧化碳。结果表明，斯达基酵母对百草枯的降解与细胞壁的完整性有关，细胞壁的破坏或去除会导致降解能力完全丧失。推测了该生物体降解百草枯的机制。
