摘要：我们研究了东京不同水生环境中具有壬基酚（NP）降解活性的微生物群落。在东京湾和某污水处理厂的废水中观察到具有显著活性的微生物。对于第一个样品的微生物，在含有NP （1000 ppm）作为唯一碳源的培养基中，在25°C的45天孵育中，约70%的NP被降解。对于第二个样品的微生物，NP在30天内几乎完全降解，并且随着降解活性的增加，多次成功降解。在另一种NP/葡萄糖摩尔比为1的培养基中，降解活性不受葡萄糖的影响。
SUMMARY: We studied microbial consortia with nonylphenol (NP)-degrading activities from various aquatic environments in Tokyo. The microbes with notable activity were observed in two locations: Tokyo Bay and waste water of a sewage treatment plant. For the first sample’s microbes, about 70% of NP was degraded in 45 days’ incubation at 25°C in the medium containing NP (1000 ppm) as a sole carbon source. For the second sample’s microbes, NP was almost completely degraded in 30 days and succeeded several times with the increase of the degrading activities. In another medium in which the NP/glucose mole ratio was 1, the degrading activities were not affected by glucose.
