Abstract

Aeromycoflora of Bilaspur city was studied during March 2009 to Feb 2010. Total 1760 fungal spores represented 21 fungal types were observed during the present investigation period. Cladosporium oxysporum showed the maximum percentage contribution of aero-mycoflora with the percentage of (14.09%), was followed by Alternaria alternata (10%). Both Trichoderma sp. (1.07%) and Bispora sp.(1.25%) showed the minimum percentage contribution of aero mycoflora were observed. Higher concentration of spores was observed during August (263) and lower concentration in the month of April(80). Out of total flora Aspergillus sp, Cladosporium sp., Curvularia sp and Aspergillus niger are allergenic in nature.

Introduction

A great variety of fields are represented under the umbrella of aerobiology, including plant, human and animal pathology, entomology, air pollution effects, palynology, phytogeography and meteorology .  Aerobiology is the study of airborne biological material, chiefly pollens and spores and their transport on other ogranisms.               Microorganisms always present in the nature and they migrate through one place to another by air current. Fungus is the common microorganisms in our environment, and always present in form of spores. Airborne  dusts containing fungal spores are associated with a range of respiratory  diseases. The study of airborne fungal spores enables their occurrence to be related to the incidence of respiratory symptoms in exposed individuals. The particulate materials considered important in aerobiology include smokes and dusts, radio nuclides, pesticides and the biological forms, bacteria, fungi, fragments and spores of algae, protozoa and fern spores, pollen, plant fragments, minute seeds, insects and other micro fauna.

Materials and Methods

During the present investigation gravity Petri plates methods was used for aeromycological survey of Bilaspur city . The survey conducted for one year March 2009 to Feb 2010 . Ten sterilized Petri plates containing PDA medium will expose for 5-10 minutes at different places of Bilaspur  city at one meter height above the ground level. Then the Petri plates, brought into the laboratory and incubated at  26±1⁰c. for seven days. At the end of the incubation period the percentage contribution and percentage frequency were assessed^. At the end of incubation period the fungal colonies were counted, isolated and identified with the help of available literature. (Ellis, 1949 ; Barnett, 1969 ; Nagmani et al. 2006).

Results and Discussion

During the investigation period total 1760 fungal colonies belonging to 21 species from 13 genera were observed. Out of which 444 fungal colonies in summer, 628 in rainy & 688 in winter season were observed (Fig.1). Percentage frequency and percentage contribution were also observed during investigation period. Cladosporium oxysporum  showed the maximum percentage contribution of aero-mycoflora with the percentage of (14.09%), was followed by Alternaria alternata (10%). Both Trichoderma sp. (1.07%) and Bispora sp.(1.25%) showed the minimum percentage contribution of aero mycoflora  were observed (Table-1) Out of total flora Aspergillus sp, Cladosporium sp., Curvularia sp and Aspergillus niger are allergenic in nature.

. Aspergillus sp. was observed throughout the study period similar result was also reported by Tiwari et al. (2006). Anamorphic fungi recorded as the most contributed fungal group throughout the study period similar result also recorded by (Jadhav and Tiwari 1994; Tiwari et al.  2005).
