Funalia gallica, Lenzites tricolor, Polyporellus brumalis, Pseudotrametes gibbosa, Pycnoporus sanguineus, tested their degrading ability to david poplar wood lignin, measured the lignin content change of david poplar wood after a period of time degraded by 6 wood rot fungi, which is the first study on the biodegradation mechanism of lignin by wood white rot fungi.

本项研究选择了火木层孔菌及另外5种木材分解能力较强的阔叶树上的白腐菌：粗毛盖菌、三色革裥菌、冬拟多孔菌、偏肿拟栓菌和血红密孔菌，研究了它们对山杨木材木质素的分解能力，测定了经6种白腐菌分解一定时期的山杨木材木质素的含量，作为木材白腐菌对山杨木材木质素生物降解机制的初步研究，旨在为山杨木材生物制浆造纸提供应用基础理论研究，同时也可为木质素合理的生物转化为有用的化学品、生物漂白、酶处理防止机械浆的返黄、废水治理、纤维素酶解糖化的微生物前处理等提供相关的借鉴研究，以期在生产实践中减轻环境污染并充分利用木质素资源。

This strain is able to degrade polycyclic aromatics such as naphthalene and biphenyl as well as monocyclic aromatics such as phenol. Under experimental conditions, strain DF51 is capable of degrading at concentrations of phenol ranging from 100 mg to 800 mg, which is catabolized mainly through the catechol 1, 2-dioxygenase pathway with a minor catechol 2, 3-dioxygenase pathway.

DF51。在本实验条件下，菌株DF51能够有效降解浓度范围为100-800mg L-1的苯酚，该菌代谢苯酚主要是通过邻苯二酚1， 2-双加氧酶催化开环途径进行，同时辅以邻苯二酚2， 3-双加氧酶催化开环，表明菌株DF51兼有混浊红球菌(Rhodoccocus opacus R7)和红球菌PNAN5Rhodoccocus sp。

Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.

从119个菌株中分离筛选出了6株细菌和5株霉菌，它们可以在含有木质素的培养基上良好生长：细菌分类学鉴定结果为X1、X2和X3：假单胞菌属，X4和X5：黄单胞杆菌属，X6：枝动杆菌属；对6株细菌降解木质素性能进行了初步的研究，选定X2和X4为实验用菌种，两株菌适宜的生长温度为30℃，最适初始pH值为7；经紫外线照射诱变法处理，可使它们产生的三种木素分解酶活性均有明显的提高，细菌增长速率比诱变前明显提高。
