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.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。
