A method is described for inhibiting marine fouling on a surface. The surface is contacted with a composition comprising a waterborne polyurethane that is crosslinked with an acrylic acid functionalized polysaccharide, water, and a preservative. The composition is then dried to form a deposited film. The polysaccharide may be xanthan.

A method of fractionating lignocellulosic biomass includes fractionating lignocellulos biomass in an aqueous phenol-4-sulfonic acid (PSA). The process may provide complete or nearly complete fractionation under mild conditions.

The present disclosure relates to a novel hydrogel, and to method of making and using the novel hydrogel. The novel hydrogel is a reaction product of a water soluble laccase cross-linked arabinoxylan and an acid, and has a pH value of 1.5-2.5.
