Abstract

An aeromycological survey of different Bus stand environments in Puducherry District

Bijaya Kumar Nayak

ABSTRACT

n aeromycological study at five different bus stands environments in Puducherry District was carried out during January to March 2015 by volumetric Burkard’s sampler on agar plates. During the study period, total number of 3440 fungal colony forming units (CFUs) were isolated from all the five sites, among which Gorimedu bus stand contributed the maximum of (30%) followed by the Thanthaiperiyar bus stand (22%), New bus stand (11%), Villianur bus stand (18%) and old bus stand (11%). Among the recorded taxa, members of Aspergillus spp, were predominant in their occurrence, followed by the members of Cladosporium spp. In qualitative analysis, altogether 15 fungal species under 9 genera were isolated from all the sites. Data on fungal occurrence revealed that the Aspergillus sp, Cladosporium sp. and Penicillium sp. were the highest in all the five sites chosen for study. Fungal species like, Aspergillus niger, Aspergillus flavus, Cladosporium, Curvularia palescens, Pink sterile mycelia, Penicillium chrysogenum, Penicillium citrinum were predominant in the bus stand areas. Besides, the dominant ones, contributing substantially to the total fungal CFUs, a large number of fungal types recorded incidentally one or three times during the study period contributing thus very negligibly. Keywords: Aeromycological survey, Bus stand, Burkard’s sampler, Fungal CFUs, Taxa.
