SAMEERA NAZIM, SHAHNAZ DAWAR, MARIUM TARIQ AND M.J. ZAKI
Abstract
Thirty samples of water and 10 samples of fruit juices were tested for the presence of mycoflora. pH value of water samples ranged from 7.4-10.25 and those of juice samples from 4.03-6.23. Four genera belonging to 9 species of fungi were isolated from water whereas 4 genera and 8 fungal species were isolated from juices using direct plating techniques. In serial dilution technique, 6 genera and 11 species were isolated from water whereas 3 genera and 8 species were isolated from juice samples. Highest number of fungi were isolated by serial dilution technique followed by direct plating method. Aspergillus niger was found to be dominant fungus in drinking water as well as in juice samples followed by A. clavatus and A. ustus.
