Effects of different lignocellulosic substrates on laccase production by white-rot fungi in solid-state fermentation
摘要
Abstract
Twenty-four newly isolated strains of white-rot fungi were cultured on guaiacol-supplemented medium for screening laccase-producible strains,the capacity of laccase production of the 12 strains obtained was analysed in submerged fermentation and solid-state fermentation on different lignocellulosic substrates.The results indicated that there was no significant correlation between the laccase activity detected under submerged fermentation conditions and the ratio of colony diameters to photochromic laps among the 12 test strains(P>0.05).Similarly,no significant association was observed between the laccase activity detected during solid-state fermentation on different lignocellulosic substrates and the ratio of colony diameters to photochromic laps for the various test strains(P>0.05).In submerged fermentation,Cerrena unicolor LKY 798,Trametes hirsuta LKY 831,Funalia trogii LKY 846,and Neofavolus alveolaris LKY 850 exhibited comparatively high laccase activities keeping for a fairly long duration.N.alveolaris LKY 850 and Trametes sp.LKY 797 demonstrated the strongest laccase production capacities under solid-state fermentation condition using leaves of Quercus variabilis,Populus beijingensis,and needles of Pinus tabuliformis as substrates.It seems that leaves of Quercus variabilis and Populus beijingensis are more suitable than needles of Pinus tabuliformis for laccase production under solid-state fermentation condition.Additionally,Trametes sp.LKY 797,F.trogii LKY 846,and N.alveolaris LKY 850 showed relatively good laccase activities in fermentation using needles of Pinus tabuliformis as the substrate,with maximum laccase activities exceeding 3 700 U/mL.关键词
