“…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). Laccase (EC 1.10.3.2, p-benzenediol: oxygen oxidoreductase) belongs to a family of copper oxidases and widely distributes in various higher plants, fungi, bacteria, and some insects (Zhang et al, 2020).…”
