General description
2-Formylbenzenesulfonic acid sodium salt reacts with chitosan in the presence of sodium cyanoborohydride to yield N-benzyl derivatives.
Application
2-Formylbenzenesulfonic acid sodium salt was used as precursor to test the ability of fungal strains for transformation of phenolic and non-phenolic precursors into stable and non-toxic dyes.

In this study, water-soluble, narrow-band-gap polymers containing reactive groups were prepared by the addition-condensation of pyrrole (Pyr), benzaldehyde-2-sulfonic acid sodium salt (BS), and terephthalaldehydic acid (TPA) or p-hydroxybenzaldehyde (p-HB). TPA and p-HB were used for the post-crosslinking reaction between polymers.

Chemical methods of producing dyes involve extreme temperatures and unsafe toxic compounds. Application of oxidizing enzymes obtained from fungal species, for example laccase, is an alternative to chemical synthesis of dyes. Laccase can be replaced by fungal biomass acting as
