“…Previous studies indicated that lignocellulosic materials, belonging to a type of complex carbon and nitrogen sources, could be affected the laccase production secreted by fungi (Pinar et al 2017;Leite et al 2019;An et al 2020b;Han et al 2020;Rajavat et al 2020). Widely used kinds of lignocellulosic materials were wood chips, olive pomace, wheat bran, bamboo, and coffee shells (Gaikwad and Meshram 2019;Leite et al 2019;Xu et al 2020). The planting area of corn, cotton, Populus beijingensis, and Oryza sativa is large, so there are large amounts of corresponding residues.…”

“…What is more serious is that these agro-and forestry residues will cause more air pollution if they were disposed of via burning. However, these agro-and forestry residues belonging to biomass resources have broad application value in various aspects including green energy fuels and industrial chemical products (Gaikwad and Meshram 2019). Agro-and forestry residues, e.g., sugarcane bagasse, grasses, corncob, cottonseed hull, bamboos, etc., are composed of lignin, cellulose, and hemicellulose (Pinheiro et al 2020).…”

Laccase activity from Pleurotus ostreatus and Flammulina velutipes strains was investigated with various agro- and forestry residues by solid-state fermentation. Different species or strains belonging to the same species had the unique capacity of secreting laccase on solid-state fermentation with various agro- and forestry residues. Overall, the capacity of secreting laccase for P. ostreatus strains was superior to F. velutipes strains due to the value of maximum activity on various agro- and forestry residues, except on the stalk of straw. Compared with Populus beijingensis, corncob, and stalk of straw, the presence of cottonseed hull was helpful to improve laccase activity for P. ostreatus strains because the maximum laccase activity from cottonseed hull was higher than that from the other three agro- and forestry residues. The presence of stalk of straw was more helpful to improve laccase activity for F. velutipes strains because of the maximum laccase activity from stalk of straw was higher that from Populus beijingensis, corncob, and cottonseed hull. These results indicated the importance of selecting suitable agro- and forestry residues for fungi producing laccase. These findings contributed to the selection of suitable strains to obtain an integrated application of low-cost laccase in the factory.

“…Lignocellulosic biomass, as the most abundant and cheapest renewable eco-friendly resource on Earth, is usually disposed of in a simple and crude way, such as burning it or piling it up to rot, causing serious air pollution. Meanwhile, lignocellulosic biomass has attracted increasing attention due to its ability to be converted into other types of products, such as bioenergy and other chemicals (An et al 2020(An et al , 2021Atilano-Camino et al 2020;Gaikwad and Meshram 2020;Han et al 2021a). Producing enzymes with lignocellulosic biomass through the method of solid-state or submerged fermentation has been widely accepted by researchers.…”

Laccase has huge potential application in all aspects of biotechnology due to the ability of laccase to oxidize a wide range of phenolic and non-phenolic compounds. The future success of such applications requires large amounts of laccase with low costs. White-rot fungi are important groups of laccase production. In this study, three white-rot fungi, Phlebia acerina Han 618, Trametes hirsuta Han 726, and Coriolopsis trogii Han 751, isolated from a native North China habitat, were identified by the method of molecular biology and preliminary screening of the ability of laccase-production by guaiacol selection medium. Then they were fermented on different lignocellulosic biomass. Three species showed consistency in preference of lignocellulosic biomass, and the presence of stalk of Sorghum bicolor was more suitable for secreting laccase. The capacity of laccase secretion from different species was significantly different. The capacity of secreting laccase of C. trogii Han 751 was superior to that of P. acerina Han 618 and T. hirsuta Han 726. The discovery of a new strain with superior capacity of secreting laccase and suitable lignocellulosic biomass were helpful for laying a foundation for the optimization of the fermentation conditions for the highest laccase production, the isolation and purification of laccase, and the industrial application of laccase.

“…Agricultural and forestry waste is an important kind of lignocellulosic biomass. Lignocellulosic biomass, versatile and most abundant natural renewable resources, have attracted more attention and considerable interest due to their abilities to convert into green second-generation energy fuels and valued industrial chemicals via the various bio-treatment process of lignocellulosic biomass (Haldar et al, 2016;Pinar et al, 2017;An et al, 2020b;Gaikwad and Meshram, 2020). Using various lignocellulosic wastes, such as corncob, cottonseed hull, bamboos, coffee shell, and tree leaves, to produce enzymes (especially laccase) had been widely investigated in recent years due to the low-cost and vast amounts of lignocellulosic wastes (Lizardi-Jimenez et al, 2019;Thamvithayakorn et al, 2019;Wang et al, 2019;Agrawal and Verma, 2020;Atilano-Camino et al, 2020;Pinheiro et al, 2020;Xu et al, 2020).…”

“…The effect of using two or three white-rot fungi combined with each other to produce laccase was rarely investigated ( Kuhar et al, 2015 ; Vibha and Negi, 2018 ). Most studies had used only one lignocellulosic material to explore the effect on laccase secreted by fungi, and very few had considered using a mixture of two lignocellulosic materials to explore the effect on laccase secretion by fungi ( Lallawmsanga, Leo et al, 2019 ; Thamvithayakorn et al, 2019 ; Unuofin et al, 2019b ; Gaikwad and Meshram, 2020 ; Xu et al, 2020 ). However, evaluation of laccase activities from C. unicolor , Lenzites betulinus , and Schizophyllum sp.…”

Three newly isolated fungal species, namely, Cerrena unicolor Han 849, Lenzites betulina Han 851, and Schizophyllum commune Han 881, isolated from their native habitats in Wulingshan National Nature Reserve of Hebei Province of northern China, were screened for laccase production with single or mixed lignocellulosic wastes. C. unicolor Han 849 was found to express the highest levels of laccase with single or mixed lignocellulosic wastes compared with L. betulina Han 851 and S. commune Han 881. The highest laccase activity from the mixed fungal culture of C. unicolor Han 849 and S. commune Han 881 or L. betulina Han 851 on Firmiana platanifolia was 1,373.12 ± 55.93 and 1,144.85 ± 34.97 U/L, respectively, higher than that from other tested conditions. L. betulina Han 851 or S. commune Han 881 mixed with other species was also helpful for accelerating laccase secretion due to reach maximum enzyme activity quickly. The treatment of mixing different species, including the mixture of two or three species, was obviously conducive to the improvement of laccase activity on Firmiana platanifolia. These results revealed that the fungal co-culture and the mixed lignocellulosic wastes contribute to the improvement of laccase activities and enhance laccase activities within a short period. These findings would be helpful for providing a new method for rapid production of low-cost laccase and for optimization of integrated industrial laccase production.
