The effect of incubation time on most-probable-number estimates of autotrophic nitrifying bacteria was investigated by using waters, rooted aquatic plants, sediments, and slimes as inoculum sources. Maximum most probable numbers of the NH4+-oxidizing group were attained in 20 to 55 days (median, 25). Estimates of NO2-oxidizers were highest at termination (103 to 113) days.
通过使用水、水生植物根系、沉积物和黏液作为接种源,研究了培养时间对自养硝化细菌最大可能数估计值的影响。在20至55天(中位数为25天)内,NH4+氧化菌群的最大可能数达到最高。NO2-氧化菌的估计值在培养结束时(103至113天)最高。
