Biodegradation of tetrabromobisphenol-A in sludge-amended soil

This study investigated the degradation of tetrabromobisphenol-A (TBBPA) and changes in the bacterial community in sludge-amended soil. The results indicated that TBBPA degradation was enhanced by spent mushroom compost (SMC), enzyme extract (EE) and extract-containing microcapsule (MC) in soil-sludge mixtures, with SMC showing a greater TBBPA degradation rate than the other additives. The TBBPA degradation rates were enhanced with SMC at the second and third additions. The bacterial composition differed in the soil-sludge mixtures with and without SMC. Bacillus, Flavobacterium, Geobacter, Mycobacterium, Pseudomonas, Rhodococcus, Sphingomonas and Streptococcus were major bacterial communities in TBBPA degradation in the soil-sludge mixtures.
