... investigate the effect of cellulolytic enzymes on MSW degradation [73]. Econase consists mainly of endo-1,4-h- D-glucanase, cell obiohydrolase, and exo-1,4-h-D-glucosidase in addition to a number of other ... For example, as shown in Fig. 8, solutions of 3- chlorophenol, 4-chlorophenol, 2,6-dichlorophenol, 3-methylphenol, and 4- methylphenol were substantially detoxified during tr...
