The research on the conditions of chlamydospore production for the liquid fermentation showed that, the better single factors were oat liquid media, 30℃, 120r/min surge culture, sucrose as carbon source,(NH_4)_2SO_4 as nitrogen source and the ratio of 20 to 1 for C/N. Under the better single factors mentioned above, the largest quantity of chlamydospore, i.e.3.05×10~7spores/ml, was obtained on the 10th day after culture.

综合各项指标得出，HFW-05菌株生长的最适碳源为蔗糖，产孢量与产酶量最大，分别为16.13×10^7孢子／平方公分和117.38μg/；最适氮源为豆粕粉，其产孢量和酶活远高于对照和无机盐类，分别为15.62×10^7孢子／平方公分和74.01μg/。

Various inorganic acid, such as ammonium chloride, copper sulfate, aluminum sulfate, mercury chloride, cerium sulfate and cerium chloride, have been evaluated for copper powder, zinc powder, or tin powder-mediated allylation reactions of carbonyl compounds with allyl bromide in aqueous medium.

结果表明：在同样的反应条件下，与铜粉或锌粉作用的此类反应相比，锡粉能更好的作用羰基烯丙基化反应，并且该反应的产率都比较高；在同样的金属促进剂存在下，硫酸亚铈的促进性能是所有无机酸中最好的。 2、研究了二氧化碳促进羰基化合物烯丙基化反应。

The results indicated that the optimal components of free medium for Ascomycetes SD-9701 producing red pigment was rice flour 20 g,yeast power 5 g and water 1 000 mL.

Aspergillus WQ is selected to explore the factors which affect producing enzymes. The best carbon source is crystallitic cellulose+straw powder, the best nitrogen source is peptone+yeast abstract cream, the best growing temperature is 35℃and the best initial pH is 5.5. WQ can produce the largest quantity of enzymes after being cultivated eight days.

从50℃左右牛粪自然堆肥中筛选了一株产酶量较高的曲霉WQ，对影响其产纤维素酶的因素和酶的热稳定性进行了初步研究，结果表明：液体发酵时，该菌最佳碳源是微晶纤维素+稻草粉组成的复合碳源，最佳氮源是蛋白胨+酵母膏的复合氮源，最适生长温度为35℃，最适起始pH值为5.5，在生长第8天产酶量最高。

Nevertheless, the yield of pinacol was also strongly affected by the steric environment surrounding the carbonyl group. The pinacol coupling of aromatic aldehydes has been achieved with high yields under such a condition. However, the diastereose-lectivities of pinacols were not satisfying. Unfortunately, the ketones and most aliphatic aldehydes appeared inert under the same reaction conditions.

然而， 呐偶合反应的产率受到羰基周围环境的立体位阻影响较大，在此条件下，锌粉能有效地促进芳香族醛类化合物进行水相呐偶合反应，得到的呐醇产率高，但非对映异构体选择性差，而脂肪族醛类化合物得到的呐醇产率较低，在同样的条件下，酮类化合物不能顺利进行呐偶合反应。

The production and characterization of endoglucanase from Streptomyces xylophagus KX6 was studied. Maximum endoglucanase yield of 0.538 IU/ml was achieved with medium pH8.0, containing CMC2Na 1.0% as carbon resource, soybean meal 1% as nitrogen resource, 2% inoculating volume, 30% 250 ml triangle flask bulk for medium volume at 40℃ 200r/min shaker for 48h.
