本論文主要目的為探討當以Flavobacterium sp.(ATCC 39723)好氧批次式反應實驗來分解不同濃度的PCP時(五氯酚、50-150 ppm)，在特殊鹽類培養基中添加不同的碳源，對此菌種生物分解性的影響。並藉由菌體粒徑和菌體表面電位的測定來分析菌體膠凝沈降性和生物分解性間的關係。 實驗結果發現，在純PCP中添加其他碳源可以減少Flavobacterium sp.生長的遲滯期，其中以Glutamate和glucose為碳源時，分解PCP的速度最快，而以Cellobiose為碳源時則是最慢，此和其他文獻（33）有相同的結果。在純PCP培養基中，菌體溶液的穩定度會有最小值出現；添加其他碳源的菌體溶液之穩定度則會隨著培養時間的增加而增加，且會隨著PCP濃度的增加而變小。 The main purpose of this thesis is to discuss the influences of the different carbon sources added in the special miner salts on the biodegradation of various concentration of PCP (Pentachlorophenol) by Flavobacterium sp.(ATCC 39723) in the aerobic batch system. The relationship between bioflocculation and biodegradation of Flavobacterium sp. is investigated by measuring Zeta potential and diameter of this bacterium. Experimental results, demonstrated that the lag phase of Flavobacterium sp. can be shorten by adding different corbon sources. The degradation rate of PCP of this bacterium is the fastest when using glutamate and glucose as the carbon sources and is the slowest when using cellobiose. Stability ratio of the solution has the minimum value on the pure PCP media. The higher concentration of PCP, the better the flocculation behavior of this bacterium.
