Effect of temperature and pH on keratinophilic fungus Chrysosporium indicum in vitro conditions

Abstract

Hyphomycetes includes keratinophilic, dermatophytes and non dermatophytes filamentous fungi. Keratinophilic fungi growth is effected by biotic and environmental factors. Evaluation of effect of pH and temperature as physical conditions was observed . In the present investigation the steps have been undertaken to study the effect of temperature and Ph on keratinophilic fungus Chrysosporium indicum in vitro condition. The study of fungus has specific range of favourable pH and temperature. The normal growth of chrysoporium inducing was observed between 250C to 350C, where maximum growth and speculation was observed at 30. There has been a drastic reduction in fungal growth below 100C or 150C and speculation and growth declined at above 350C. So, it is observed that between 25 0C to 350C fungal growth and sporulation occur favorably .Below 100C and above 350C did not favour the growth and reproduction of keratinophilic fungi. Effect of hydrogen ion concentration was observed particularly for Chrysosporium indicum. Favourable hydrogen ion concentration for mycelial growth was 7.00. In present study Chrysosporium indicum fungal hyphae growth was changed with pH and the maximum growth was found at the end of incubation day is about pH 7 to 7.5
