2.2 Isolation of Endophytic Fungi
The samples were washed thoroughly with sterile
distilled water. The materials were then surfaces
sterilized using ethanol 75% (1 min), 0.5% sodium
hydrochloride (3 min), and ethanol 75% (30 s) and
rinsed thoroughly with sterile distilled water. The
samples were grinded using sterile mortar. 1 g of
samples was put in 9 mL NaFis and vortexed.
Furthermore, 1 mL of aliquot was plated onto potato
dextrose agar (PDA; 12 g Difco potato dextrose broth,
20 g agar/L, with streptomycin 100 mg/L) using spread
plate technique. The plates were then incubated at
room temperature until fungal growth appeared (1-3
week). Each fungal colony was transferred into PDA
for purification of fungal strain. The fungal isolates
were identified based on their morphological and
reproductive characters.
