| 摘 要： | 筛选出２株真菌，产色链霉菌（Ｓｔｒｅｐｔｏｍｙｃｅｓｃｈｒｏｍ ｏｇｅｎｅｓ）和立枯丝核菌（Ｒｈｉｚｏｃｔｏｎｉａ ｓｏｌａｎｉ）具有转化ＮＯ－３ 的活性⒚它们的活性甚至比枯草芽孢杆菌（Ｂａｃｉｌｌｕｓｓｕｂｔｉｌｉｓ）还强⒚产色链霉菌和立枯丝核菌将ＮＨ＋４ 转化为ＮＯ－３ 的机理也不同于真菌尖孢镰刀菌（Ｆｕｓａｒｉｕｍ ｏｘｙｓｐｏｒｉｕｍ ）必需有ＮＯ－３ 或ＮＯ－２ 的诱导才具有活性，它们可直接将硫酸铵转化为ＮＯ－３ ，进而再将ＮＯ－３ 转化为ＮＯ－２ ⒚此结果为研究新的硝化抑制剂提供了重要的理论根据

| Abstract: | The activity of two fungus, Rhizoctonia solani and Streptomyces chromogenes, transforming NO - 3 into NO - 2 was found in this study The both of fungus directly converted (NH 4) 2SO 4 to nitrate and then nitrate was reduced to nitrite During the transformation,the fungus do not need inducement by nitrate and nitrite,this is different from Fusarium oxysporium ,that Hirofumi Shoun et al reported before |
