Two inducible and extracellular chitosanases secreted by Penicillium sp. D-l were purified by ammonium sulfate precipitation as well as gel filtration. The purified enzymes of ChoA and ChoB had molecular masses of 93 and 21 kDa by SDS-PAGE. Both ChoA and ChoB have an acidic pH optimum, which were 4.0. The enzymes were stable over the pH range 3 to 5 for 1 h.

The removal of these impurities by three kinds of active carbon(coaly activated carbon,fruit hull activated carbon,woodiness activated carbon) are studied under different experimental conditions.The results show that the fruit hull active carbon is not suitable for the removal of the impurity in bittern of salt lake because its removing rate of COD and turbidity is ...

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。

Results indicated that the four GACs can remove the DBP effectively at 35℃, and the removal rate is over 90%; Maximum adsorption capacity of 52.52 mg/g、29.90 mg/g、159.3 mg/g、147.2 mg/g at equilibrium were achieved for the Coaly carbon1.0、Coaly carbon1.5、nut shell and coconut shell activated carbons respectively.

结果表明：35℃时，4种活性炭均能有效地去除DBP，去除率高达90％以上；煤质1.0、煤质1.5、果壳和椰壳饱和吸附量分别为52.52 mg/g、29.90 mg/g、159.3 mg/g和147.2 mg/g。

The mixture of corn and wheat bran were good food bases. Inoculation proportion and water content were key factors affecting conidial production.

结果表明：蛭石和稻壳均可作为固相培养的优良载体，以蛭石为载体的产孢量稍高于稻壳。
