Diversity of phosphate solubilizing bacteria and fungi from andisol soil affected by the eruption of Mount Sinabung, North Sumatra, Indonesia

Abstract. Sembiring M, Sabrina T. 2021. Diversity of phosphate solubilizing bacteria and fungi from andisol soil affected by the eruption Mount Sinabung, North Sumatra, Indonesia. Biodiversitas 23: 713-719. Phosphate microbes are present in all locations with different population levels. The Sinabung 2013 resulted changes pH soil’s microbial population, such as microbes. This research aimed to obtain environmentally-specific derived impacted which excelled increasing availability phosphate. Sampling was conducted Desa Kutarayat, Naman Teran Sub-district, Karo District, Sumatra Province, Isolation carried out on pikovskaya media, test potential solid liquid media. Organic acid content determined using high performance chromatography (HPLC) identification performed PCR-sequencing. result showed that 4 isolates each phosphate-soluble were isolated mountain. It also observed microbes’ ability produce organic acids varied. obtained could dissolve P some source either media or medium. Talaromyces pinophilus (J2) can increase highest soil.
