A study looked at how to remove a common textile dye called remazol black B from wastewater using a type of fungus called Ganoderma sp. and its enzymes. The researchers found that using the enzymes from the fungus was more effective than using the fungus itself. The best conditions for dye removal were a pH of 6 for the fungus and a pH of 4 for the enzymes, with a dye concentration of 70 mg/L and a 7-day incubation period. The color removal efficiency was around 90% for both the fungus and its enzymes. This shows that Ganoderma sp. and its enzymes could be a good way to treat wastewater from the textile industry.
