添加不同菌剂海水水族箱硝化功能建立过程的比较研究

分别选取自制硝化细菌、德彩、喜瑞和科迪4种硝化细菌制剂,研究其对海水水族箱硝化功能建立过程的影响。结果表明:添加不同硝化细菌海水水族箱硝化功能建立过程明显不同,自制硝化细菌制剂组海水水族箱氨氮在5 d达到峰值,11 d降至最低;德彩、喜瑞和科迪组则分别在15 d、13 d和17 d达到峰值,30 d、36 d和30 d降至最低;自制硝化细菌制剂组海水水族箱中亚硝酸盐在21 d达到峰值,在40 d降低至检测不出;德彩硝化细菌、喜瑞硝化细菌和科迪硝化细菌组亚硝酸盐分别在46 d、59 d、68 d到达峰值,德彩、喜瑞组亚硝酸盐分别在69 d、75 d降至检测不出,而科迪组亚硝酸盐直至实验结束仍维持在较高浓度(80 mg/L)。

Effect of four kinds of nitri f ying bacteria inoculums on the construction of nitrification function in marine aquarium

Four nitrobacteria which were made by our lab ,Tetra ,Sera ,BioDigest ,respectively ,were selected in the present study .The effect of four nitri f ying bacteria inoculums on the construction of nitrification function in marine aquarium was researched .The results showed the construction of nitri-fication function in marine aquarium were very different with different nitrobacteria .After input of ni-trobacteria which were made in our lab ,ammonia nitrogen peaked at 5 d and decreased to minimize at 11 d .On the other hand ,ammonia nitrogen peaked at 15 d ,13 d ,17 d after input of nitrobacteria which were made by Tetra ,Sera ,BioDigest ,respectively ,and decreased to minimize after 30 d ,36 d an d 30 d .Moreover ,nitrite peaked at 21 d and decreased to test out at 40 d after input of nitrobacte-ria which were made in our lab .Nitrite peaked at 46 d ,59 d ,and 68 d after input＆nbsp;of nitrobacteria which were made by Tetra ,Sera ,BioDigest ,respectively .And nitrite decreased to test out at 69 d ,75 d after input of nitrobacteria which were made Tetra ,Sera ,respectively .Nitrite remained at high concentration levels （80 mg/L） till the end of experiments after input of nitrobacteria w hich w ere made by BioDigest .
