A study on predominance of keratinophilic flora in soil of Jaipur, India
Abstract
Fungi are heterotrophic organisms possessing cryptic lifestyles and have an individual hierarchy in the evolution of microorganisms on earth. Out of which, Keratinophilic fungi are allied molds that produce keratinase enzymes and diminish the keratin matters in or on the soil. Fifty soil samples were collected from various sites of Jaipur district, India to analyze incidence of keratinophilic fungi. Out of 162 isolates, a total of 24 keratinophilic fungal species of 13 genera were recovered, including Trichophyton sp. (17.90%), Aspergillus sp. (17.90%), Chrysosporium sp. (14.81%). Selective keratinophilic fungi were also discussed about phylogenetic studies. In multiple sequence alignment of sequences, species were reported to have closest relationships between teleomorphic and anamorphic form of keratinophilic fungi which exhibited a reason for phase changes between geophilic and dermatophytic fungi by accident or opportunistic where they may cause infections in both humans and animals on the opportunity. In the anti-fungal activity, Eucalyptus globulus (Inhibition Zone: 23.5 mm; Activity Index: 0.82) and Ocimum tenuiflorum (Inhibition Zone: 20.75 mm; Activity Index: 1.46) were inscribed to dispense a greater potential of antifungal activity against all selected keratinophilic fungi.
