Growth of?Paecilomyces hepiali?in various agar media and
yield of fruit bodies in rice based media were?studied. The best growth in
agar media was obtained at 25℃?(61.86 mm colony diameter in 14 days). The initial agar media pH
range?from?6 to 8 was found to be?the?most favourable for mycelial
growth. This study found that agars made with powders of cereal grains alone do
not support good mycelial growth of?P. hepiali. Addition of peptone
improved mycelial growth significantly. The most favourable carbon sources were
Mannose, Fructose and Glucose. Organic nitrogen sources were found to be?the?most
preferred. The results demonstrated that brown rice is better than polished
rice in yield of fruit bodies. Addition of peptone was found to be quite
significant in enhancing yield of fruit bodies. Peptone, as a supplement, gave
a better yield than addition of egg yolk, albumen and a mixture of the two. The
medium with?40 g brown rice, 0.325 g glucose, 0.65 g sucrose, 2 g peptone
and 65 ml corn steep liquor was found to be?the?most favourable and it
yielded 19.3 g of fresh fruit bodies.
