由水質實驗的代謝表現、變性梯度凝膠電泳法(Denaturing Gradient Gel Electrophoresis, DGGE)圖譜與菌群染色觀察發現下可知本研究的除磷系統在葡萄糖馴養的情形下，體積負荷比磷負荷對系統的影響較大，因此相對的對菌群的影響力也大，且兩反應槽的進流葡萄糖濃度與系統的除磷效率成反比。在低體積負荷時，兩反應槽有部份的釋磷/攝磷現象，而經由厭氧批次實驗可知，兩者所馴養的菌群在攝取葡萄糖與醋酸時有明顯的差異，當以乳酸為基質時，微生物亦不能適應，且由PHA的組成可知兩反應槽的代謝途徑不同。當兩反應槽提高負荷後，發現兩者幾乎沒有除磷效率，經由厭氧批次實驗可知，兩者所馴養的菌群在攝盡葡萄糖後，會殘留部份不易分解的有機碳，且菌群更不能適應醋酸為碳源，而微生物攝取不同碳源時，PHA皆以3HV為主要組成。
由PHA、Neisser與glycogen染色實驗得知，單一形態菌種似乎只具有某種特定的功能，即反應槽所表現的總代謝反應為各別種菌群所表現的代謝反應的總集合。本研究亦利用氧化還原染劑INT(3-(4-lodophenyl) -2-(4-nitrophenyl)-5-phenyl- 2H-tetrazoliumchloride)得知，在無外部碳源時，所馴養出的菌群會利用胞內的碳源進行呼吸作用。
由DGGE分析菌群得知，在低負荷階段長期穩定馴養時，菌群的消長來維持反應槽動態的平衡，而DGGE圖譜經由聚類分析得知，進流體積負荷對菌群結構的影響大於磷負荷對菌群的影響。以螢光原位雜交法(fluorescence in situ hybridization, FISH)分析菌群結構發現GH反應槽的菌群大部分分佈在domain Bacteria中的beta-Proteobacteria和gram positive high G+C，而又以四連球形態出現的gram positive high G+C為最多，且推測其有大量累積肝醣的功能與有多樣性，而屬於beta-Proteobacteria的桿菌則有累積PHA的功能。

In this study, two SBR reactors fed with glucose as main carbon source but with different influent P/C (2/100, 6/100 respectively) were operated at low (0.158 kg-COD/m3-d) and high (0.316 kg-COD/m3-d) volumetric loadings to study the biochemical characteristics and microbial community structures of systems influenced by glucose. Operational experiment results indicated that sludge from both reactors displayed anaerobic phosphorus release and aerobic uptake at low loading stage. As the influent loading was increased, the release and uptake of phosphorus were ceased. Anaerobic batch experiments showed that sludge from different influent P/C ratio reactor both absorbed glucose and transformed it into carbohydrate. When acetate replaced glucose as substrate, extracellular carbon was absorbed slowly and accumulated mainly as polyhydroxyalkanoate (PHA) while intracellular carbohydrate was degraded. Sludge assimilated glucose first and utilized acetate as glucose and acetate were mixed as carbon source. As lactate was applied, it was degraded by sludge slowly; this showed that no lactate utilizing bacteria existing in the SBRs.
On the aspects of microbial community structure, cluster analysis of DGGE spectrum exhibited that bacterial communities were more impacted by volumetric loading rather than by influent P/C ratio. Fluorescence in situ hybridization (FISH) showed that almost 50% of DAPI-stained cell were Gram-positive HGC members and appeared tetrad forming morphologically. The second predominant group was cocci belonged to the beta-Proteobacteria and it accounted for 10-30% DAPI stained cell. The Gram-positive HGC tetrad-forming bacteria were diversified in the polyphosphate accumulating ability but they didn’t accumulate PHA. On the other hand, the beta-Proteobacteria cocci accumulated PHA but not polyphosphate. In general, the polyphosphate and PHA accumulating traits showed in batch experiments were the sum of separate physiological traits of different phylogenetical bacterial group.
