Indigenous endomycorrhiza of iron and manganese contaminated soils in Indonesia

Concentrations of iron and manganese that exceed critical limits in soil and plant
provide opportunities for microorganisms to become resistant. The aim of this study
was to identify endomycorrhizal fungi from areas contaminated with iron and
manganese for use as biostarter for phytorizoremediation programs. This research was
conducted in two phases at April 2019, namely taking rhizosphere from Chromolaena
odorata, Melastoma affine dan Spathoglottis plicata in Sorowako, Indonesia; and the
second phase is to isolate and identify endomycorrhizal fungal spores in the
Microbiology Laboratory, Center for Environmental and Forestry Research and
Development in Makassar, Indonesia. The results showed that the genus Acaulospora
was more dominant in areas that were contaminated with iron and manganese, and
were able to adapt and survive compared to other genera.
