Evaluation the feasibility of mycofiltration applied in aquaculture system

Abstract

The aquaculture industry worldwide now faced the biggest problem is diseases that cause due to various biological and non-biological agents. Among the groups of microorganism that cause serious losses in shrimp culture, the best known are bacteria, mainly due to Vibrio because of the devastating economic effects they have on affected farms. This study help to provide scientific data and information on mycofiltration to treat aquaculture wastewater without harming aquatic organism, practically remove of Vibrio parahaemolyticus without causing critical mortality in shrimps. Follow the previous study of other student, four types of white rot fungi ( include”Flavodon flavus”, “Physisporinus vitreis”, “Pleurotus ostreatus” and “Schizophyllum commune”) that had significant removal and inhibited ability of Vibrio parahaemolyticus in liquid medium, with the initial removing percentage up to 90% of Vibrio parahaemolyticus CFU/100ml after 4 and 8 hours during treatment, will be continue to use in this study. These four types of fungi were culture in liquid medium to act as the enzyme to kill and inhibit the growth of Vibrio parahaemolyticus for first evaluation. For second evaluation, they were grow-out in environment to develop mycelium and act as filter to treat waste water, also prevent Vibrio parahaemolyticus.
