Lignin degradation: microorganisms, enzymes involved, genomes analysis and evolution (2017, background): “During ligninolysis, other substrate-derived oxidants are produced such as alkoxyl ( OR) and peroxyl ( OOR) radicals but they are less reactive than Fenton reagents (Hammel et al. 2002).”
Recent updates on different methods of pretreatment of lignocellulosic feedstocks: a review (2017, background): “Removal of lignin from lignocellulose exposes cellulose and hemicellulose leading to increased enzymatic hydrolysis (Hammel et al. 2002).”
Biological pretreatment of lignocellulosic biomass--An overview. (2016, background): “Reactive oxygen species (ROS) play an important role in wood decay by fungi (Hammel et al., 2002).”
Polymer biodegradation: mechanisms and estimation techniques. (2008, background): “They can interact with low molecular weight molecules (Call and Mücke, 1997; Zapanta and Tien, 1997; Hammel et al., 2002; Hofrichter, 2002), that could lead to the formation of free radicals and consequently to oxidise and to cleave of polylignols bonds (Otsuka et al., 2003).”
Access to cellulose limits the efficiency of enzymatic hydrolysis: the role of amorphogenesis (2010, background): “This attack is thought to increase pore size, consequently enhancing the diffusion of cellulases within the substrate [71-78].”
