Outline of Final Research Achievements

Endophytic fungi (EPF) were isolated from forest soil and their function was clarified in order to remediate post opencast mining land in Indonesia. Thirty-three EFP were isolated by trap culture and those isolates increased growth of Brassica campestris andParaserianthes falcataria. Degree of increase was affected by nutrient concentration in media. More thant 10 new compounds were identified from 6 EPF. These results suggest that EPF can be used for remediation of post opencast mining land.
