Abstract The effects of a naturally occurring Patagonian strain the white-rot fungus Pleurotus ostreatus on Araucaria araucana wood lignans was evaluated. Lignans colonized and non-colonized shavings activity fungal ligninolytic enzymes were studied. identified using gas chromatography with mass spectrometry detector. Only eudesmin lignan resisted biological degradation. highest laccase 0.111 ±...

This study aimed to assess the phytoremediation potential of Ricinus communis L. for heavy metals remediation via rhizospheric bacterial activities distillery wastewater detoxification and management. Results revealed that contained high levels other physico-chemical pollution parameters could cause environmental aquatic toxicity. The identified bacterium produced several plant growth-promoting...

Cultures of the ligninolytic fungus Irpex lacteus incubated in a nutrient liquid medium degraded more than 70% of the initially applied benz[a]anthracene within 14 days. At the first step of metabolization, benz[a]anthracene was transformed via a typical pathway of ligninolytic fungi to benz[a]anthracene-7,12-dione (BaAQ). The product was further transformed by at least two ways, whereas one is...

BACKGROUND Olive pomace, as the main by-product of the olive oil industry, is recently recycled as fermentation substrate for enzyme production. OBJECTIVES Actinobacteria isolates were separated from an Algerian soil under olive pomace cultivation and were evaluated for their lignocellulolytic enzymes production. MATERIALS AND METHODS Isolates of Actinobacteria were separated from soils aro...

The development of alternative energy technology is critically important because of the rising prices of crude oil, security issues regarding the oil supply, and environmental issues such as global warming and air pollution. Bioconversion of biomass has significant advantages over other alternative energy strategies because biomass is the most abundant and also the most renewable biomaterial on...

Fungi have unique properties and are used in many areas of agriculture industry because they can produce different enzymes. This study aims to the fungal diversity peat soil from Pontian Johor, Malaysia. The isolates were described on culture media a new medium called EVA identified using phenotypical characteristics molecular D1/D2 domain 28S large subunit ribosomal RNA (28S rRNA) ITS (ITS1-IT...

We investigated whether manganese peroxidase (MnP) and the laccase-mediator system with 1-hydroxybenzotriazole (HBT) as mediator can remove the estrogenic activities of the steroidal hormones 17beta-estradiol (E(2)) and ethinylestradiol (EE(2)). Using the yeast two-hybrid assay system, we confirmed that the estrogenic activities of E(2) and EE(2) are much higher than those of bisphenol A and no...

Panaeolus sphinctrinus, Panaeolus papilionaceus, and Coprinus friesii are described as producers of ligninolytic enzymes. P. papilionaceus and P. sphinctrinus both produced a laccase. In addition, P. sphinctrinus produced a manganese peroxidase. C. friesii secreted a laccase and two peroxidases similar to the peroxidase of Coprinus cinereus. The purified laccases and peroxidases were characteri...

Image analysis technique was applied to identify morphological changes of pellets from white-rot fungus Trametes versicolor on agitated submerged cultures during the production of exopolysaccharide (EPS) or ligninolytic enzymes. Batch tests with four different experimental conditions were carried out. Two different culture media were used, namely yeast medium or Trametes defined medium and the ...
