Abstract:
采用FISH技术对2008年冬、夏两季太湖梅梁湾水体中细菌优势种群的丰度进行了对比分析。实验中,选取荧光素标记的特异寡核苷酸探针,与太湖梅梁湾水体中的四类细菌优势种群α-变形菌(α-proteobacteria),β-变形菌(β-proteobacteria),γ-变形菌(γ-proteobacteria)和拟杆菌(Bacteroidetes)进行原位杂交。结果表明:①所测定的四类细菌优势种群占总细菌的比例在冬季均显著高于夏季(P<0.01);②水体中α-proteobacteria的丰度随TP浓度的增加而显著增加(R2=0.860,P<0.01);③随着Chl.a浓度的增加,水体中细菌的丰度呈上升的趋势,尤其是其中的γ-proteobacteria,其增大趋势更加显著(R2=0.857,P<0.01);④细菌种群的丰度受水体中PO43-浓度的影响,尤其是对Bacteroidetes的影响更加显著(R2=0.733,P<0.05)。
