Evaluation ability of mycofiltration to treat aquaculture Waste water

Abstract

Aquaculture waste water caused many environment problem such as pathogen and eutrophication. This study assessed the efficiency of new approach – mycofiltration to treat aquaculture wastewater, practically to remove of Escherichia coli and Chemical Oxygen Demand, Total Nitrogen, Total Phosphorus. Fungi were collected in nature and market sources and transferred mycelium to substrate with 100% rice husk to form mycofilter. Among 6 isolated fungal species, two unknown white rot fungi UN1 and UN6 had significant removal of E. coli in liquid medium, with the initial amount of E. coli 1000 – 2000 CFU/100ml and after 4 and 8 hours of incubation. Mycofilter UN1 and UN6 were then evaluated the capacity of removing total bacteria and Chemical Oxygen Demand, total nitrogen, total phosphorus. Mycofilter UN6 had the best performance in bacteria removal with 85.9%. Key word Mycofiltration White rot fungi Escherichia coli Wastewater 1
