This study deals with the optimization and extraction of such colorants from Penicillium minioluteum for the purpose of dyeing different protein...
A colorant from Penicillium minioluteum behaving like an acid dye was identified, extracted, purified, and characterized. It was used for dyeing wet blue goat nappa skin at different pH, time, and temperature to standardize these parameters. Highest color depth and percentage dye exhaustion was achieved at pH 2.0 (altered after 30 min of dyeing), temperature 80 °C, and time 60 min. Study of dyeing...
