碩士 === 東海大學 === 化學工程學系 === 90 === 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.
