PEROMBAKAN AIR LIMBAH TEKSTIL MENGGUNAKAN JAMUR PENDEGRADASI KAYU JENIS Polyporus sp TERAMOBIL PADA SERBUK GERGAJI KAYU

White-rot fungi produce ligninolytic enzymes including lignin peroxidase (lip) and manganese peroxidase (mnp). these enzymes can be applied to degrade azo textile dyes. the objective of this research was to study the potential of white-rot fungus which is identified as polyporus sp. for degrading textile wastewater. the polyporus sp. was evaluated its ability to decolorize azo dyes such as remazol black b and remazol red rb in solid media. hereafter, the fungus was immobilized on sawdust and the results are used to reduce textile wastewater in an aerobic reactor system. the results revealed that the polyporus sp. fungus immobilized on sawdust in an aerobic reactor system provides efficiency to decrease cod value up to 75,23%, bod 79,94%, tss 53,18% and decolorization of textile dyes up to 73,48% within 7 days. acute toxicity test showed that moderate toxic textile categorized textile wastewater became less toxic.
