Separation of lignosulfonate lignin into antibacterial lignin oligomer fractions
Introduction: Antibiotic resistance is rising globally, increasing the demand on new antibacterial substances. Background: Studies suggest that lignin exhibits antibacterial properties, however this property is unexploited commercially. The valorization of lignin is difficult due to its complex and variable structure. Aims: This study aims therefore to fractionate lignosulfonate lignin (LSL) into
