Isolation of Lignin from Anaerobically Digested Unhydrolyzed Solids Produced in a Biorefinery
Agriculture, 2022 About 30–40% of lignin-rich unhydrolyzed solids (UHS) are left behind after subjecting lignocellulosic biomass to thermochemical pretreated processes followed by enzymatic hydrolysis (EH) to produce sugars that are fermented to fuels and chemicals in a ...

Microbial characteristics of biogas
Water Science and Technology, 2008 The microbial diversity of biogas was analyzed in order to examine the aerosolization behavior of microorganisms. Six biogas samples were analyzed: five from mesophilic and thermophilic anaerobic digestors treating different wastes, and one from landfill. Epifluorescent microscopic counts revealed 106 prokarya m−3.
