2.3. Determination of antifungal activity by parallel streak
method
Antifungal activity tested by the parallel streak method
was done according to the research work reported by Lee
[26]. Modified and unmodified foam rubber samples were
placed on the Suborn Dextrose Agar (SDA) culture medium
and a thin SDA gel layer (10 ml) was again poured on the
foam rubber samples. The parallel streaks were drawn on
the top gel layer using a loop touched with fungal colonies
of Aspergillus niger. The samples were incubated at 37 C for
72 h and the fungal growth on streaks was visualized on
textile samples.
