Endophytic fungi isolation was carried out under aseptic condition. The outer bark of each
sample was detached with a sterilised sharp blade, cleaned by washing with running tap water several
times and soaked in 70% (v/v) ethanol for 10-20 min. It was then washed several times with
sterilised
water, dipped into 0.1% HgCl2 for 1-2 min, again washed with sterilised water 3-5 times and then put
into a beaker of sterilised distilled water.
