“…The presence of lignocellulosic material can induce the production of MnP and laccase, both described as having a synergically action in the degradation of lignin and industrial effluents (Kumaran et al 1997;Hofrichter et al 1999;Rodrigues et al 1999;Zhao et al 2008). The expected result for the analysis would be in an observation period of the two enzyme peaks, beginning with laccase and consequently with MnP activity, as observed in the present work.…”

Vinasse is a highly colored effluent with a high pollutant potential when disposed in the environment. Assays for decolorization of vinasse were performed, selecting the fungus Pleurotus sajor-caju CCB 020. The discoloration was cocominant with the increase of the activities of laccase, manganese-peroxidase and peroxidases. P. sajor-caju demonstrated a rise in biomass production (1.06 g 100 ml -1 ), and the enzyme activities such as laccase (varying from 400 to 450 IU l -1 ) reached between the 9th and 10th day of growth and for MnP at the 12th day of cultivation (varying from 60 to 100 IU l -1 ). It was concluded that the system P. sajor-caju/vinasse can be utilized as a bioprocess for color removal and degradation of complex vinasse compounds. It was observed an improvement in the characteristics and detoxification allowing its utilization as reused water, laccase and manganese-peroxidase enzymes production and for fungal biomass production with a high nutritional value.

“…It shows that at the early stage at 2-8 days, there was a significant biodegradation of lignin in culture, removal rate of lignin increased quickly up to its maximum 65% after day 8 of incubation. Ligninolytic enzymes of white-rot fungi are generally produced under N-limited media (Janshekar et al 1982;Zhao et al 2008). The fungi A. wentii, Chaetomium cellulolyticum, Humicola fuscoatra and Sporotrichum thermophile decreased the lignin absorbance only to a smaller extent (16-20%) under sufficient nitrogen supply.…”

A fungus strain F-3 was selected from fungal strains isolated from forest soil in Dalian of China. It was identified as one Aspergillus sp. stain F-3 with its morphologic, cultural characteristics and high homology to the genus of rDNA sequence. The budges or thickened node-like structures are peculiar structures of hyphae of the strain. The fungus degraded 65% of alkali lignin (2,000 mg l(-1)) after day 8 of incubation at 30°C at pH 7. The removal of colority was up to 100% at 8 days. The biodegradation of lignin by Aspergillus sp. F-3 favored initial pH 7.0. Excess acid or alkali conditions were not propitious to lignin decomposing. Addition of ammonium L: -tartrate or glucose delayed or repressed biodegradation activities. During lignin degradation, manganese peroxidase (28.2 U l(-1)) and laccase (3.5 U l(-1))activities were detected after day 7 of incubation. GC-MS analysis of biodegraded products showed strain F-3 could convert alkali lignin into small molecules or other utilizable products. Strain F-3 may co-culture with white rot fungus and decompose alkali lignin effectively.

BACKGROUND Polycyclic aromatic hydrocarbons (PAHs) are hazardous contaminants. Bio‐based technology is among recommended practices for the recovery of PAH contaminated matrices. The objective of the study was to validate the exploitation of spent mushroom substrate (SMS), an organic waste deriving from the industrial production of Pleurotus ostreatus, as bulking agent in a dynamic biopile pilot plant, because of the SMS potential oxidative capacity towards aromatic recalcitrant compounds. The dynamic biopile pilot plant treated 7 tons of a historically PAH contaminated soil (6469 ± 423 mg PAHs kg−1), classified as dangerous waste. RESULTS The mixing of SMS with soil was mandatory for the depletion of PAHs, which after 8 months, were at significantly lower concentrations (112 ± 5 mg PAHs kg−1). The treated soil was capable of reintroduction to the industrial site of origin. However, a residual genotoxicity of soil elutriates at the end of the process was measured on root tips of Vicia faba L. CONLUSIONS The SMS derived from the industrial production of P. ostreatus is exploitable as a versatile low cost organic substrate with oxidative capacity towards PAHs and its exploitation as a bulking agent in biopiles is advantageous for the disposal of the organic waste. © 2016 Society of Chemical Industry
