title: [Remediation of pentachlorophenol-contaminated soil by composting with inoculation of white rot fungi].
abstract: In the experiment four parallel beakers A, B, C,D were adopted, among which A was without any inoculum, B was added with the inocula of immobilized Phanerochaete chrysosporium, C was inoculated with non-immobilized Phanerochaete chrysosporium, and D was only with pentachlorophenol (PCP)-contaminated soils open to air. By contrastive analyses, the feasibility of applying composting to the bioremediation of the PCP-contaminated soil was discussed. It can be seen from the experimental results that composting with inocula was better than that without innoculation and after 60d composting, more than 94% PCP in the compost was degraded; meanwhile the effect by immobilized fungi was better than that by nonimmobilized one. From the experimental data it shows that the PCP degradation achieved 50% on 9d by immobilized fungi. What's more, shown by indicators of germination index, volatile solids, microbial carbon activity and other factors, the compost were mature and of no hazard to plant at the end, which provided the benign environment for the Phanerochaete chrysosporium to degrade the PCP so that the bioremediation and composting could be combined together.
