Abstract
Waste from the textile industry is dominated by synthetic dyes. Synthetic dyes are complex organic components that are quite resistant to environmental conditions so they are very damaging to ecological systems. The decolorization process can be carried out with the help of biological agents. One biological agent that also has potential for the decolorization process of synthetic dyes is the brown rot fungus, Aspergillus niger. The information and literature review explained in this article refers to the latest research regarding the potential decolorization of synthetic dyes by the fungus Aspergillus niger. The literature review was carried out by analyzing qualitative data, making observations, and drawing conclusions from research journals. The results of the study show that the Aspergillus niger fungus has quite good potential, even the percent removal of synthetic dyes can reach ± 90% through biodegradation and biosorption processes that work simultaneously. There are several factors that influence the removal mechanism, such as: pH, agitation conditions, temperature, initial dye concentration, and nutrient composition.
