© 2020 The Textile Institute.Determination of dye biosorption capacity by lichen biosorbent and reusability of the waste lichen biosorbent as an antimicrobial agent are the aims of this study. The study has three stages: 1. to carry out dye biosorption assays, 2. to scan antimicrobial activity of waste lichen biosorbent after dye loaded, 3. to examine the antimicrobial function of a fabric which absorbed waste lichen extract. The optimal conditions for the best dye biosorption were determined. After the biosorption experiments, the waste lichen biomass was harvested from the working solution and the extraction of dye-loaded waste biomass was done using methanol and ethanol. The extracts obtained from both dye-loaded and un-loaded biosorbents were scanned for antimicrobial activity potential by the disk diffusion method. The results of this study showed that the waste lichen biosorbent of biosorption processes can be reused as antimicrobial agents.
