Abstract

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.

摘要

地衣生物吸附剂对染料生物吸附能力的测定以及废地衣生物吸附剂作为抗菌剂的可重复使用性是本研究的目标。该研究分为三个阶段：1.进行染料生物吸附测定； 2.扫描加载染料后的废地衣生物吸附剂的抗菌活性； 3.检查吸收了废地衣提取物的织物的抗菌功能。确定了最佳染料生物吸附的最佳条件。经过生物吸附实验后，从工作溶液中收集了废地衣生物质，并使用甲醇和乙醇提取了负载染料的废生物质。通过圆盘扩散法扫描从负载染料的和未负载生物吸附剂中获得的提取物的抗菌活性潜能。
