Air-borne mycoflora of Rohtas Fort

Air-borne fungal spores were collected on two different culture media viz malt extract agar (MEA) and potato dextrose agar (PDA), from five different sites of Rohtas Fort, Chakwal, Pakistan. A total of seven fungal species belonging to three different genera namely Alternaria, Aspergillus and Drechslera were isolated. Aspergillus niger was found to be the most prevalent (25.75%) fungal species followed by Alternaria alternata (24.08%), Aspergillus fumigatues (21.73%), Aspergillus candidus (12.37%), Drechslera spicifer (5.68%), Drechslera sp.(5.35%) and Drechslera neergaardii (3.34%).
