Styrax sumatranus J.J.Sm endophytes fungi and its potential as phosphate solubilizing and cellulose decomposition

Abstract

Abstract Styrax sumatranus J.J.Sm is a plant from North Sumatra, which is widely used by community for religious rituals, medicines and it has economic value. Endophytic fungi are fungi that harbour inside the plant tissue without causing any negative effects to their host plant. Endophytic fungi isolated from the leaves and bark of Styrax sumatranus J.J.Sm. The aim of this research was to obtain endophytic fungi that have potential as phosphate solubilizing and cellulose decomposition. The bark and leaves of Styrax sumatranus J.J.Sm as a source of endophytic fungi were taken from Pandumaan village, Pollung District, Humbang Hasundutan Regency, North Sumatra. Test the potential of endophytic fungal as phosphate solubilizers using selective Pikovskaya media and as cellulose decomposition using carboxyl methyl cellulose (CMC) media plus congo red 0.1%. Then calculate the phosphate solubility index and cellulolytic index. The result show that, of 20 isolates tested, there were 12 isolates that had potential as phosphate solubilizers and 12 isolates had potential as cellulose decomposition. Phosphate solubility index dan cellulolytic index obtained range from 2.10-2.44 and 0.22-0.55 respectively.
