Biodegradation of polystyrene, poly(metnyl methacrylate), and phenol formaldehyde.
The biodegradation of three synthetic 14C-labeled polymers, poly(methyl methacrylate), phenol formaldehyde, and polystyrene, was studied with 17 species of fungi in axenic cultures, five groups of soil invertebrates, and a variety of mixed microbial communities including sludges, soils, manures, garbages, and decaying plastics. Extremely low decomposition rates were found. The addition of cellu...
متن کاملBiodegradation and effect of formaldehyde and phenol on the denitrification process.
Formaldehyde and phenol biodegradation during the denitrification process was studied at lab-scale, first in anoxic batch assays and then in a continuous anoxic reactor. The biodegradation of formaldehyde (260 mgl(-1)) as single carbon source and at phenol concentrations ranging from 30 to 580 mgl(-1) was investigated in batch assays, obtaining an initial biodegradation rate around 0.5g CH(2)Og...
متن کاملBiodegradation of phenol
The use of microbial catalysts in the biodegradation of organic compounds has advanced significantly during the past three decades. It has been found that large numbers of microbes co-exist in almost all natural environments, particularly in soils. Many natural and synthetic organic chemicals are readily biodegradable in natural environment. Biodegradation of materials involve initial proximity...
متن کاملPhenol Biodegradation: A review
The release of phenolic compounds in the effluents of petrochemical, textile and coal industry has resulted in contamination of receiving environment. It is very necessary to remove these compounds before discharge of effluents as phenol is toxic to nature. Among the treatment methods biodegradation is considered as cost effective method. The paper reviews various methods used for biodegradatio...
متن کاملSynthesis of Humin-Phenol-Formaldehyde Adhesive
Humins are low-value-added byproducts from the biomass acid hydrolysis process. In the present work, humins were first employed as a phenol replacement for synthesis of modified phenol-formaldehyde adhesives through a two-step process. In this process, humins were first utilized to obtain alkaline soluble products, mainly consisting of phenolics, through a hydrothermal process. The obtained alk...
