Tailor-made alkaliphilic and thermostable fungal laccases for industrial wood processing
Biotechnology for Biofuels and Bioproducts, 2022 Background During the kraft process to obtain cellulosic pulp from wood, most of the lignin is removed by high-temperature alkaline cooking, released in the black liquors and usually incinerated for energy. However, kraft lignins are a valuable source of
