Abstract
A third study on the biodegradation of pentachlorophenol (PCP) (100 mg L−1) by micromycetes was done with 784 strains of Deuteromycetes cultivated in liquid synthetic medium. The disappearance of PCP after 5 days of cultivation was compared with POx production. Mean PCP depletion was 56% for Agonomycetales, 60% for Coelomycetes, 51% for Dematiaceae, 52% for Mucedinaceae (other than Aspergillus and Penicillium), 56 and 57%, respectively, for Aspergillus and Penicillium, and 42% for Tuberculariales. Although some genera gave homogeneous results (Ascochyta, Aspergillus, Coniothyrium, Penicillium), a great variability was observed as well in PCP depletion as in POx production, reflecting the heterogeneity of this artificial taxonomic group. With a few exceptions, correlation between POx production and PCP disappearance was low or nonexistent. Another factor, probably not enzymatic, could be involved. © 1994 by John Wiley & Sons, Inc..
微菌对五氯酚的生物降解。3半知菌纲
用784株在液体合成培养基中培养的后菌对五氯酚(PCP) (100 mg L−1)的生物降解进行了研究。将培养5 d后PCP消失量与痘菌产量进行比较。agonomyceales的PCP平均耗用率为56%，coelomycales为60%，Dematiaceae为51%，Mucedinaceae(曲霉和青霉菌除外)为52%，Aspergillus和Penicillium分别为56%和57%，Tuberculariales为42%。尽管一些属给出了均匀的结果(Ascochyta, Aspergillus, Coniothyrium, Penicillium)，但在PCP消耗和痘产生方面也观察到很大的差异，反映了这一人工分类群的异质性。除了少数例外，痘产生和PCP消失之间的相关性很低或不存在。另一个因素，可能与酶无关。©1994 by John Wiley & Sons, Inc.。
