主要探讨了厦门凤林湾秋茄林(Kandelia candel)土壤、秋茄与无瓣海桑(Sonnerratia apetala)混合林土壤与无红树植物生长的对照光滩土壤中3大微生物类群及其数量.实验结果表明:3种土样的微生物中,细菌占有绝对优势,占总菌数的99%以上;秋茄林土样和混合林土样中的细菌和丝状真菌数量明显高于光滩土样,而放线菌数量却低于光滩土样;初步筛选鉴定出秋茄纯林土样中细菌菌种主要是微球菌属(Micrococcus)、异常球菌属(Deinococcus)和芽孢杆菌属(Bacillus),混合土样中细菌菌种主要为异常球菌属和芽孢杆菌属,而从对照光滩土样中分离纯化出的2株菌初步鉴定为微球菌属和不确定菌属(Uncertainty genus).
主要探討瞭廈門鳳林灣鞦茄林(Kandelia candel)土壤、鞦茄與無瓣海桑(Sonnerratia apetala)混閤林土壤與無紅樹植物生長的對照光灘土壤中3大微生物類群及其數量.實驗結果錶明:3種土樣的微生物中,細菌佔有絕對優勢,佔總菌數的99%以上;鞦茄林土樣和混閤林土樣中的細菌和絲狀真菌數量明顯高于光灘土樣,而放線菌數量卻低于光灘土樣;初步篩選鑒定齣鞦茄純林土樣中細菌菌種主要是微毬菌屬(Micrococcus)、異常毬菌屬(Deinococcus)和芽孢桿菌屬(Bacillus),混閤土樣中細菌菌種主要為異常毬菌屬和芽孢桿菌屬,而從對照光灘土樣中分離純化齣的2株菌初步鑒定為微毬菌屬和不確定菌屬(Uncertainty genus).

The experimental results on the microbial groups in the three different soils which were sampled from the mangrove area,mixed area of mangrove Sonnerratia apetala,and mudflat respectively were presented.According to the results,it was found:1)the bacteria were the majority in the three samples(more than 99 %);2)the bacteria and filamentous fungi in the samples of mangrove area were obviously much more than those of mudflat,but the number of actinomyces was smaller;3)The bacterial strains in the sample of Kandelia candel forest soil were preliminarily identified as Micrococcus,Deinococcus and Bacillus,the bacterial strains in the sample of mixed forest soil were preliminarily identified as Deinococcus and Bacillus,and the bacterial strains in the sample of mudflat as Micrococcus and Uncertainty genus.
