Unrestricted and reckless use of antibiotics has resulted in their accumulation in environment. This, in turn, has led to the emergence of multiple drug-resistant microbes. The present study focuses on degradation of ciprofloxacin (CIP) by an edible white rot fungus Pleurotus ostreatus. Effect of CIP was determined on radial growth and biomass of P. ostreatus. Titrimetric and spectrophotometric...

Dead wood is an important microsite for seedling regeneration in forest ecosystems. Although recent studies have found associations between fungal decay type (white rot and brown rot) both density species composition of regenerating seedlings, its abiotic biotic mechanisms are unknown. In the present study, pot experiments were conducted with seedlings two ectomycorrhizal tree (Abies veitchii B...

Industrially produced carbon-based nanomaterials (CNM), including fullerenes and nanotubes, will be introduced into the environment in increasing amounts in the next decades. One likely environmental chemical transformation of C60 is oxidation to C60 fullerol through both abiotic- and biotic-mediated means. Unfortunately, knowledge of the environmental fate of oxidized CNM is lacking. This stud...

Three wild-type white rot fungi and two cellulase-less mutants developed from Phanerochaete chrysosporium K-3 (formerly Sporotrichum pulverulentum) were tested for their ability to delignify grass cell walls and improve biodegradation by rumen microorganisms. Fungal-treated and control stems of Bermuda grass were analyzed for their content of ester- and ether-linked aromatics by using alkali ex...

Phenolic resins, phenol-formaldehyde polymers previously thought to be nonbiodegradable, are produced at an annual rate of 2.2 million metric tons in the United States for many industrial and commercial applications. Three independent lines of evidence established their biodegradability with the white-rot fungus Phanerochaete chrysosporium. Chromatic transformation of growth medium (yellow to p...

One oxidase (EC 1.10.3.2) and three lignin peroxidases (EC 1.11.1.-) were purified from the culture liquid of the white-rot fungus Phlebia radiata Fr. All the enzymes were glycoproteins. The oxidase had Mr 64,000 and the lignin peroxidases I, II and III had Mr values 42,000, 45,000 and 44,000 respectively. The lignin peroxidases were found to share common antigenic determinants: lignin peroxida...

Harvesting green sugarcane with chopper harvesters results in up to 24 Mg/ha of post-harvest residue. Soil microorganisms can decompose residues and offer numerous ecological and economical benefits to growers; however, the process is dependent on the biotic density, diversity and activity in the soil. Further, the decomposition process is unfavourably slow such that sugar yields are adversely ...
