The most suitable range of temperature is 25~30℃ and lethal temperature is 56℃ for hypha growth, the most suitable temperature is 25℃ for produce more conidiospore and lethal temperature is 56℃ for conidiospore. Within the pH range of 3~11 the hypha could grow and produce conidiospore. The optimum pH is 5~7 for hypha growth and 3, 9, 10 for produce more conidiospore. The range of glucose concentration is 2%~8% for hypha growth, the most suitable glucose concentration is 2% for hypha growth and produce more conidiospore. The effect of illumination on Bipolaris cynodontis was significance to the growth hypha and spore numbers. The whole light is advantage of hypha growth, but could not produce conidiospore. Alternation of light and darkness for 12 hours is advantage of hypha growth, as well as produce conidiospore.

菌丝最佳生长温度是25~30℃之间，在25℃时最利于产孢，菌丝生长和分生孢子的致死温度是56℃；该菌在pH 3~11范围内均能生长，产生分生孢子，菌丝生长的最适pH 5~7，产孢量最大的pH是3，9，10；糖浓度在2%~8%菌丝能生长，在糖浓度为2%时菌丝生长最好，产孢量最高；光照对病原菌的菌丝生长和产孢有明显影响，在全光照的条件下有利于菌丝的生长，但不会产孢，黑暗12h光照12h既利于菌丝生长又利于产孢，而全黑暗的条件下不利于菌丝生长和产孢。

S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu. The microorganism inhibition experiment by filter papers indicated that the extract of E. humifusa had higher inhibition effect against bacteria than on pathogenic fungus. Diameters of the zone of inhibition of salmonellas, Echerichia coli and Staphylococcus aureus were 15.77mm, 12.27mm and 10.53mm respectively. The extract of E. humifusa had a certain effect against Colletotrichum lagenarium, Botrytis cinerea, Rhizoctomia solan and Pyricularia oryza but no effect against Helminthosporium maydis and Gibberella zea. The 4 cation exchange resins and ethanol deposition were used to isolate the active fractions from supernate after alkali deposition.

提取液对黄瓜白粉病菌体外分生孢子萌发抑制实验表明地锦提取液对黄瓜白粉病菌分生孢子的萌发有很好的抑制作用，抑制率随着地锦提取液浓度的增大而增高，当浓度为20mg/mL时，抑制率达到100%，即使在浓度为2.5mg/mL时，抑制率也达到了67.66%；室内盆栽苗期预防性实验表明了地锦提取液对上海4个不同地区的黄瓜白粉病菌均具有不同程度的抑制效果，对七宝和宝山地区的菌株抑制效果优于南汇和青浦地区的菌株；用滤纸片法测定了地锦提取液的抑菌谱，实验结果表明地锦提取液对供试的4种植物病原真菌：黄瓜炭疽病菌、黄瓜灰霉病菌、水稻纹枯病菌和水稻稻瘟病菌均具有一定的抑制效果，而对玉米小斑病菌和小麦赤霉病菌没有抑制效果，对供试的3种人类致病细菌沙门氏菌、大肠杆菌和金黄色葡萄球菌均具有很好抑菌效果，抑菌圈直径分别为：15.77mm， 12.27mm和10.53mm。

The citric acid-producing strain Aspergillus niger 2363-2, was isolated and used in our research. The fermentation conditions were optimized as follows: sucrose as carbon source 8. 0-14. 0%, ammonium chloride as nitrogen source 3. 0-4. 0g/l, initial pH 2. 0, and cultural temperature 30℃. The influential factors of formation of spores were also studied, and a series of measures were taken to restrain the spore formation on the basis of our experimental results. With the consideration of the cultural environment and microbial cell itself, the factors affecting the duration of citric acid-producing activity of microbial cells were examined, and it is found that undissociated citric acid and the ageing of microbial cells are the main factors. The experimental results also show that partial replacement of fermentation broth can lengthen the duration of citric acid -producing acitivity of microbial cells.

筛选出了用于试验研究的柠檬酸发酵用菌Aspergillus niger 2363-2，确定了其最适发酵条件—碳源选用蔗糖，浓度8.0~14.0%，氮源为NH〓Cl，浓度3.0~4.0g/l，发酵初始pH值为2.0，培养温度30℃；讨论了分生孢子产生的影响因素，并通过试验提出了抑制分生孢子产生的措施；从分析微生物所处的环境和微生物本身两个方面出发，探讨了影响微生物菌体产酸活性持久性的因素，认为分子态柠檬酸和菌体本身的老化是影响微生物产酸活性持久性的两个主要因素，并提出采用部分置换发酵液发酵能延长微生物菌体的产酸活性。
