【摘要】 对两种有降解二氯酚能力的假单孢菌Ｐｓｅｕｄｏｍｏｎａｓｓｐ．ＤＣＰ－１和Ｐｓｅｕｄｏｍｏｎａｓｓｐ，ＤＣＰ－２中二氯酚降解酶活性及定域进行了测定，结果表明该酶的活力与菌种、培养时间等因素有关，与诱导物的关系不显著；酶主要定域在膜周及膜内；酶的活力在两种菌中的水平相当；酶的比活力在ＣＤＰ－１的膜周处表现出相当高的水平。更多还原

【Abstract】 Activity and distribution of enzyme produced by two strains of bacteria (Psedomonas sp.DCP-1 and Psedomonas sp. DCP-2) , which can utilize dichlorophenol, have been measured.The results shown that enzyme activity is effected by bacteria and culture time, and not by inducer; the distribution of enzyme produced by the two strains of bacteria is mainly in piroplasmic and intercellular; the specific activity in piroplasmic of Pseudomonas, sp. DCP-1 is higher than that in DCP-2.更多还原
