| dc.description.abstract | In this research, four types of white rot fungi ( include” Flavodon flavus”, “Physisporinus vitreus”, “Pleurotus ostreatus” and Schizophyllum commune”.) were used to treat Vibrio parahaemolyticus the main cause of EMS/AHPND, which lead to strong impact in the shrimp aquaculture industry. This mycofiltration technique can provide an economically effective technique to solve this problem due to their recognized ability for bacteria disinfection. This research assessed salinity adaptation and Vibrio parahaemolyticus removal ability of these four types of white rot fungi. Four white rot fungi were cultured at different salt concentration from 100/00, 150/00, 200/00, to 300/00. Vibrio parahaemolyticus was treated by 3 experiment at different time (at 0, 4, 8 hours), 3 experiment include fungal suspension, fungal solution, and mycofiltration system. Results revealed that all four types of white rot fungi were effective to treat Vibrio parahaemolyticus. This study provides the basic for the use of white rot fungi in the treatment of Vibrio parahaemolyticus in shrimps. With the experiment using fungal suspension, the percentage of Vibrio parahaemolyticus removal of four types of white rot fungi were 85.78% for Pleurotus ostreatus, 98.75% for Physisporinus vitreus, and 96.53% of Schizophyllum commune and 97.83% of Flavodon flavus. The fungal solution experiment obtained 85.12% for Pleurotus ostreatus, 89% for Physisporinus vitreus, Flavodon flavus and Schizophyllum commune. However, in the mycofiltration experiment, Pleurotus ostreatus, Physisporinus vitreus, and Flavodon flavus reached approximately 100% and Schizophyllum commune reached 98% of Vibrio removal.
