“…Fungal enzyme synthesis is strongly influenced by the strain, substrate composition and nitrogen concentration in the cultivation medium (Elisashvili et al, 2008;Elisashvili and Kachlishvili, 2009;Staji et al, 2006). Among the cultivation parameters, the carbon/nitrogen (C/N) ratio is one of the most important factors to balance biomass and biocomposite productions.…”

“…There is a reduction of substratum degradation when nitrogen is excessively added (Rajarathnam and Bano, 1989). Laccase production was related to mycelial growth for P. ostreatus when C/N ratios were over 40 (Elisashvili and Kachlishvili, 2009;Staji et al, 2006). Although Pleurotus ostreatus, Lentinula edodes and Agaricus blazei are widely cultivated worldwide, little is known about the effect of C/N ratios lower than 40 on laccase production for those fungi.…”

Basidiomycetes are laccase producers used for hydrolysis of lignocellulosic byproducts in fermentative processes and could be used on biofuel production or ruminant feeding. The objective of this study was to evaluate the effect of concentrations of non-protein nitrogen sources on laccase production and mycelial growth of Pleurotus ostreatus, Lentinula edodes and Agaricus blazei. The fungi were grown on soybean hulls to which urea (U), ammonium sulfate (AS) or mixture of AS:U (1:1) were added to achieve carbon/nitrogen (C/N) ratios of 5, 15, 20 or 30. The average longitudinal mycelial growth was measured and laccase activity was determined by the oxidation of 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid. Higher C/N ratios increased mycelial growth and decreased laccase production. The highest activities were obtained with a C/N ratio of 5. P. ostreatus, L. edodes and A. blazei produced more laccase when AS, AS:U and U, respectively, were added. In addition, C/N ratios lower than 30 induced laccase syntheses, inhibited mycelial growth and were a better condition for prehydrolysis of plant residues.

“…Maximum laccase was recorded in isolate A31 (5.6U/ml) followed by 5U/ml in isolate A25. Elisashvili and Kachlishvili (2009) screened basidiomycetes for laccase production using rice straw as a substrate (17.3 U/g). Dhaliwal et al, (1991) reported that production of lignocellulolytic enzymes by Pleurotuso streatus with paddy straw.…”

“…In this condition, laccase can start to be secreted (Galhaup et al 2002). Oxidation of glucose allows for the production of hydrogen peroxide, which is necessary for peroxidase activity, another important class of enzymes responsible for the breakdown of biomass (Elisashvili and Kachlishvili 2009). All fungi need metals during their metabolism, reproduction, and differentiation.…”

The mycelial growth ability of 13 white rot fungi were separately evaluated in kraft, organosolv, and soda black liquor agar-plates. The fungus able to best grow and decolorize black liquor agar-plates was grown in organosolv black liquor to investigate whether it reduced organosolv lignin molar mass. The fungus Bjerkandera adusta showed fair mycelial growth and decolorization ability in 10% black liquor-agar plates. To obtain low-molecular weight (MW) lignin, B. adusta was cultivated in 150-mL Erlenmeyer flasks containing 10% black liquor and maintained in a shaking culture for 15 days. Lignin was recovered from each Erlenmeyer flask by acid precipitation and was analysed by size exclusion chromatography (SEC) and Fourier transform infrared (FTIR) spectroscopy. The lowest MW of lignin from black liquor was observed on the 11 th and 12 th days, at 1461 and 1790 kDa, respectively, with the polydispersity close to 1.0, indicating that the molecules were similar in size. Fourier transform infrared spectra bands showed modification of the lignin structure during 9 days, with new bands appearing after five days of lignin biodegradation.
