Ten grams of each Miang sample was homogenized in 90 ml sterile
0.85% NaCl as a diluent using a Masticator® homogenizer blender
(Barcelona, Spain) for 5 min. The homogenate was serially diluted to
10−3
–10−5 with the diluent, and 0.1 ml of each dilution was plated
on Sabouraud dextrose agar (20 g/l dextrose, 10 g/l casein enzymatic
hydrolysate, and 15 g/l agar) supplemented with 100 mg/l chloramphenicol.
The plates were incubated at 30 °C for 3 days. Morphologically
distinct yeast colonies were isolated and purified by being streaked on
YMA (3 g/l yeast extract, 3 g/l malt extract, 10 g/l glucose and 15 g/l
agar) before being stored at −80 °C in YM broth containing 15% (v/v)
glycerol.
