Abstract
Provided are aqueous lignin solutions containing lignin solvated in Good's Buffers. The aqueous lignin solutions can be used in a variety of applications including biomedical research and in manufacturing a variety of lignin containing products including food grade and biomedical products. The aqueous lignin solutions can also be used in the treatment of microbial infection, as an adjuvant in antimicrobial therapeutics or therapy, and in forming antimicrobial products. Methods of making and using aqueous lignin solutions are also described.
Claims35
An aqueous lignin solution comprising lignin solvated in a Good's buffer solution.
A method for preparing an aqueous lignin solution, comprising:
- (a) obtaining lignin, and
- (b) combining the lignin with a Good's buffer in an aqueous solution, thereby solvating the lignin.
A process of delignifying lignocellulose comprising:
- adding a Good's buffer to the lignocellulose to form a mixture, incubating the mixture for at least 5 minutes to solvate lignin in the mixture, filtering the mixture to remove solvated lignin from insoluble material, precipitating lignin with an anti-solvent, collecting precipitated lignin, and removing the anti-solvent to regenerate the GB to repeat delignification.
