Chemical and biological characterization of organic matter during composting of municipal solid waste
Composting of municipal solid waste (MSW) was studied in an attempt to elaborate transformations of organic matter (OM) during the process and define parameters for the degree of maturity of theExpand
Recycling of cattle manure : the composting process and characterization of maturity
The objective of this research was to study the composting process, changes occurring in the product during composting and product properties of relevance to its potential use as a container medium, and to evaluate possible criteria indicating compost maturity. Expand
Purification and Characterization of Laccase fromChaetomium thermophilium and Its Role in Humification
Chaetomium thermophilium laccase, which is produced during the thermophilic stage of composting, can remain active for a long period of time at high temperatures and alkaline pH values, and it is suggested that this enzyme is involved in the humification process during composting. Expand
Colonization, biofilm formation and biodegradation of polyethylene by a strain of Rhodococcus ruber
F Fourier transform infrared spectra of UV-photooxidized polyethylene incubated with Rhodococcus ruber indicated that biodegradation was initiated by utilization of the carbonyl residues formed in the photooxidization of the Polyethylene. Expand
Physico-chemical properties of commercial composts varying in their source materials and country of origin
Composting is a partially controlled bio-oxidative process through which highly heterogeneous organic matter (OM) in its solid-state transforms into a humified material. The variability of the OMExpand
Biotechnological applications and potential of wood-degrading mushrooms of the genus Pleurotus
This Mini-Review describes the properties of Pleurotus spp in relation to their biotechnological applications and potential and the use of their ligninolytic enzymes for the biodegradation of organopollutants, xenobiotics and industrial contaminants. Expand
Solid-state Carbon-13 Nuclear Magnetic Resonance and Infrared Spectroscopy of Composted Organic Matter
Use of stabilized composts as horticultural container media has been a fruitful and desirable alternative in utilization of agricultural wastes. We prepared compost from cattle manure andExpand
Metabolism of phenanthrene by the white rot fungus Pleurotus ostreatus
These experiments with cytochrome P-450 inhibitors and 18O2 labeling and the formation of phenanthrene trans-9R,10R-dihydrodiol as the predominant metabolite suggest that P. ostreatus initially oxidizesphenanthrene stereoselectively by a cyto chrome P- 450 monoxygenase and that this is followed by epoxide hydrolase-catalyzed hydration reactions.

Effect of different carbon and nitrogen sources on laccase and peroxidases production by selected Pleurotus species
Abstract Pleurotus eryngii , P. ostreatus and P. pulmonarius produced laccase (Lac) both under conditions of submerged fermentation (SF) and solid-state fermentation (SSF) with all of theExpand
