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.

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.
