So we figured, if there are places along our Fraser River that are contaminated with phthalates, and if there are bacteria that are able to live in these areas, then perhaps, perhaps these bacteria could have evolved to break down phthalates.
所以我们设想，假如弗雷泽河周边 有已经被邻苯二甲酸酯污染的地区， 同时在这些地区有可以存活的细菌， 那么也许，也许这些细菌可以进化 到分解邻苯二甲酸酯。
