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。
