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。

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.
