在前期的研究中，我们发现稻草生物炭通过吸附-生物降解耦合作用对疏水性有机污染物（HOCs）进行降解去除。然而，很少有研究确定生物炭是否会影响HOC异构体降解和异构体选择性生物降解，或者生物炭是否会改变HOC异构体特征，从而导致水环境中HOC异构体残留的变化。在这项研究中，在两个剂量（0.001和0.01克）的生物炭对10个异构体的一个典型的异雌激素壬基酚（NP）的生物降解的影响进行了评估。结果表明，生物炭对NP异构体的吸附没有影响。然而，生物炭的加入影响了特定异构体的生物降解，而不改变NP异构体的功能。用假黄单胞菌处理NP异构体，降解率为60.7 - 100%。在0.001 g生物炭处理条件下，8种NP异构体（NP 194和NP 193 a +B除外）由于其庞大的结构而被降解。当添加0.01 g生物炭时，10种NP异构体的降解受到抑制。这些研究结果表征了生物炭对NP异构体污染物的影响，为生物炭应用于NP异构体污染物的修复提供了基础信息。
In a previous study, we found that rice-straw biochar degraded and removed hydrophobic organic contaminants (HOCs) through coupled adsorption-biodegradation. However, few studies have determined whether biochar affects HOC isomer degradation and isomer-selective biodegradation or whether biochar can alter HOC isomer features, resulting in changes to HOC isomer residues in water environments. In this study, the effects of biochar at two dosages (0.001 and 0.01 g) on the biodegradation of ten isomers of a typical xenoestrogen of nonylphenol (NP) were evaluated. The results revealed that there were no effects of biochar on the adsorption of NP isomers. However, biochar addition affected the biodegradation of a specific isomer without altering the features of the NP isomers. The treatment of NP isomers withPseudoxanthomonassp.yielded degradation ratios ranging from 60.7 to 100%. At 0.001 g biochar treatment, the degradation of eight NP isomers was enhanced (except for NP194and NP193a+b) due to their bulky structures. The degradation of the ten NP isomers was inhibited when 0.01 g biochar was added. These findings characterized the effects of biochar on NP isomer contaminants and provided basic information for the application of biochar for the remediation of NP isomer contaminants.
