| dc.description.abstract | The objective of this study was to find out different white rot fungal species that have ability to remove hydrogen sulfide using mycofiltration. In nature, these fungi naturally grew on wood, but they could be artificially cultivated on agroindustrial wastes. However, the composition of substrates can affect the growth and enzyme production of fungi, therefore it is important to find out the suitable substrates. There are fungal species that are appropriate candidates for the concept of mycofiltration. In this study, hydrogen sulfide was treated by Flavodon flavus and Pleurotus ostreatus using sugarcane and sawdust as the substrate for mycofiltration. White rot fungi were cultivated in solid substrates with 20% rice bran and 60% humidity and incubated for 30 days. Then mycofiltration was set up using mycelium of these fungal species as the filter to discard hydrogen sulfide during 6 days at room temperature. After 6 days, the white rot fungi changed into dark color on the surface. The result of both treatments indicated these fungal species had the ability to treat 50-80% of hydrogen sulfide. Among them, Flavodon flavus removed the highest amount of hydrogen sulfide by 27.17 mg/L while Pleurotus ostreatus just discarded haft amount of hydrogen sulfide by 19.18 mg/L after 6 days. Moreover, the results expected to show the influence of substrates on the capacity of fungi. However, this result cannot show the significant difference in both treatments. Therefore, it may be affected by the combination of other physical and biological factors.
