FORMATION OF MICROBIAL COMMUNITIES IN OIL SHALE CHEMICAL INDUSTRY SOLID WASTES DURING PHYTOREMEDIATION AND BIOAUGMENTATION

摘要: Oil shale thermal processing has resulted in solid waste dump sites containing up to 100 million tons of waste. The processed oil contains complex mixture organic and inorganic compounds is highly toxic. Laboratory field experiments were carried out order test the effect phytoremediation bioaugmentation for remediation pollutants semi-coke. Microbial community aged (ca 10 ten years) semi-coke characterized by few dominant populations possesses low diversity. Changes microbial structure activity occurred semi- coke as a result bioaugmentation. increased number bacteria diversity well biomass. general trend was increase proportion biodegradable bacterial numbers within due treatment. Highest values all measured microbiological parameters found rhizosphere samples. Within two half year period starting from establishment plots, concentration phenolic decreased 100% products more than three times at plots with vegetation compared control. Bacterial biomass consisting strains applied experimental plots. These Pseudomonas mendocina PC1, P. fluorescens PC24 PC18 degrade phenols via catechol meta, or protocatechuate ortho combination meta pathways, respectively. Bioaugmentation biodegradation intensity 50% untreated planted controls enhanced plant growth, but on short- term. Our results indicate that proliferation specific groups, changes taxonomic catabolic genes.
