Abstract:
Amino acids are the important nitrogenous components
responsible for the growth and reproduction of fungi.
During this study 10 grams of each amino acids were
added into 50ml of sabourd dextrose (SD) liquid media.
Later on they were inoculated with isolated
dermatophytic fungi ie Microsporum canis and Histoplasma
capsulatum and incubated at 25±1ᵒc for 15 days. After 15
days grown fungal were measured. The growth performance
of M. Canis and H. Capsulatum on different amino acids
are as in order-control < tyrosine < cystein < DL
phenylalanine < L proline < L methionine < L histidine <
DL valine < DL alanine <serine < Lucien < glutamic acid
(M. Canis) , control< L cystein < tyrosine < DL
phenylalanine < L proline <L Methionine < L Histidine <
DL valine < DL alanine < L arginine < L glutamic acid <
Lucien ( H. Capsulatum) .Nitrate nitrogen which is good
for dermatophytic fungal growth is also reported to be
good for sporulation in several fungi ( Tandon & Grewal
1956 , Tandon & Chandra). H.capsulatum require cystein
and other sulphur containing amino acid for fungal
growth and yeast conversion (Sliva1958, Gallaria &
Laffer 1962, Mc vein & morion 1965, mc Ginnis1980)
