Abstract :
Eleven fungal strains were tested for their ability to produce brown and reddish brown textile dyes using H-acid (1-
naphthol-8-amino-3, 6-disulfonic acid) as a dye precursor in the fermentation medium. All tested fungal strains exhibited
high ability to produce dyes varying in both dye color (brown to reddish brown) and fastness properties to washing,
perspiration and UV light. The produced dyes were subjected to further analysis for quantitative determination of dye
components for investigation of their inter-relations as well as their role in dye color and stability.
