The Monod or Andrews kinetic parameters describing the growth of Pseudomonas sp. CPE2 strain on 2,5-dich!orobenzoic acid and 2-chlorobenzoic acid, and Al-caligenes sp. CPE3 strain on 3,4-dichlorobenzoic acid, 4-chlorobenzoic acid, and 3-chlorobenzoic acid were determined from batch and continuous growth experiments conducted in the presence or absence of yeast extract (50 mg/L). Strain CPE2 displayed inhibitory growth kinetics in the absence of yeast extract and a noninhibitory kinetics in the presence of yeast extract. Similar results were obtained for CPE3. The presence of yeast extract also resulted in a significant increase in the affinity of the strains for the chlorobenzoic acids they degraded. (c) 1995 John Wiley & Sons, Inc.
通过在有或没有酵母提取物（50毫克/升）存在的情况下进行分批和连续生长实验，确定了描述假单胞菌属CPE2菌株在2,5-二氯苯甲酸和2-氯苯甲酸上生长的莫诺德或安德鲁斯动力学参数，以及嗜碱产碱菌属CPE3菌株在3,4-二氯苯甲酸、4-氯苯甲酸和3-氯苯甲酸上生长的动力学参数。CPE2菌株在没有酵母提取物时表现出抑制性生长动力学，而在有酵母提取物时表现出非抑制性动力学。CPE3菌株也得到了类似的结果。酵母提取物的存在还导致这些菌株对它们所降解的氯苯甲酸的亲和力显著增加。(c) 1995约翰威立父子公司。
