凡纳滨对虾育苗水体中三种生物絮团的菌群多样性及Tax4Fun基因功能预测分析
|
摘要
为了解凡纳滨对虾(Litopenaeus vannamei)育苗期水体中3种生物絮团的形成过程、水质净化效果、菌群结构及功能,实验通过测定各组絮团含量和水质指标并采用Illumina MiSeq高通量测序技术,比较葡萄糖组、淀粉组和蔗糖组生物絮团的不同特征。结果显示,各组形成的生物絮团可有效调节水质,降低水体中的氨氮和亚硝酸盐氮水平。在3个碳源添加组水样中氨氮、亚硝酸盐氮和硝酸盐氮浓度显著低于对照组(P<0.05),在不同碳源组中淀粉组的氨氮、亚硝酸盐氮和硝酸盐氮的浓度显著高于葡萄糖组和蔗糖组(P<0.05);淀粉组的生物絮团沉降体积(BFV)显著低于葡萄糖组(P<0.05),蔗糖组BFV最高, 3组粒径大小呈现:蔗糖组>葡萄糖组>淀粉组; 3组样品分别测得553、515和542个OTU,菌群丰度指数Chao1、Shannon值葡萄糖组>蔗糖组>淀粉组。各组菌群在门水平中,以变形菌门(Proteobacteria)、拟杆菌门(Bacteroidetes)和浮霉菌门(Planctomycetes)为各组优势菌门, 3个菌门在各组中占比分别达到91.7%、97.6%和88.7%。在属级水平中,葡萄糖组中Oceanicella属为优势菌属,占比最高为18.4%,淀粉组中丰度较高的Muricauda、Cyclobacterium属,占比分别为9.8%和5.9%,均高于葡萄糖组和蔗糖组。在蔗糖组中Rhodopirellula属具有较高占比,较葡萄糖组和淀粉组分别高1.8%和4.1%。通过Tax4Fun法在3组中检测到细胞新陈代谢、遗传信息加工和环境信息处理等基因功能。这些功能基因在葡萄糖组中的丰度均高于蔗糖组和淀粉组。各项结果表明,凡纳滨对虾育苗水体中生物絮团不仅可以净化水质,还能提高水体菌群多样性,其中以葡萄糖作为碳源效果最好,生物絮团技术对于维持水质与水体生态系统平衡具有重要意义。
In order to explore the formation process, water purification effect, microbial structure and function of three types of biofloc in the water with Litopenaeus vannamei during hatchery period, the content of flocs and water quality index were measured, and Illumina MiSeq high-throughput sequencing technique was applied to compare the characteristics of biofloc in three groups with glucose, starch and sucrose, respectively. The results indicated that the biofloc formed in each group could effectively regulate water quality and reduce the levels of ammonia and nitrite. The concentrations of ammonia, nitrite and nitrate in the water samples from three experimental groups were significantly lower than those in the control group(P<0.05). The concentrations of ammonia, nitrite and nitrate in starch group were significantly higher than those in the glucose group and sucrose group(P<0.05). Moreover, the BFV in starch group was significantly lower than that in the glucose group(P<0.05), and the sucrose group possessed the highest BFV. The particle size of three groups was: sucrose group > glucose group > starch group. The quantity of 553, 515 and 542 OTUs was measured in the three groups respectively. Tthe microbial abundance index Chao1 and Shannon value implied the relationship in the three groups was: glucose group > sucrose group > starch group. Furthermore, regarding the phylum level, Proteobacteriae, Bacteroidetes and Planctomycetes were the dominant phylum in each group, and the proportion of three phylums in each group was 91.7%, 97.6% and 88.7%, respectively. However, in the genus level, Oceanicella was the dominant genus in glucose group, with the highest proportion of 18.4%, and the Muricauda and Cyclobacterium had the highest proportion in starch group, which were 9.8% and 5.9% respectively, and higher than those in glucose group and sucrose group. Rhodopirellula in sucrose group was 1.8% and 4.1% higher than that in the glucose group and starch group, respectively. Cell metabolism, genetic information processing and environmental information processing were detected in the three groups by Tax4Fun method. The gene function abundance in glucose group was higher than that in the sucrose and starch group. All of the results implied that biofloc in the breeding water with Litopenaeus vannamei could not only purify water quality, but also improve the microbial diversity, among which the glucose was the most effective carbon source. Nevertheless, biofloc technology is of essential to maintain the balance between water quality and water ecosystem.
