Textile industry can produce liquid waste from the dyeing process which generally contains complex structured of dyes. Biological processing of textile dye waste is considered to have advantages over physical and chemical methods, one of which is decolorization. Decolorization using biological agents such as bacteria and fungi turns out to have good effectiveness in degrading the structure of textile dyes, so it is necessary to study the decolorization mechanism to match the expected target. The mechanism of decolorization between bacteria and fungi has many similarities in term of mechanisms, which rely on two main processes, namely biosorption and biodegradation. Waste treatment with the help of microbes has been widely used, this process is often referred to as the biodegradation process. The process of biodegradation of waste generally utilizes a population of microorganisms or other products.
