Fungal spoilage of bottled mineral water.
The occurrence of filamentous fungi together with bacteriological parameters was assessed in 126 samples of still bottled mineral water of eight different commercial brands in Argentina. In spoiled samples with visible mycelium growth, the most frequently isolated fungal species were Penicillium citrinum, P. glabrum, other Penicillium species, Cladosporium cladosporioides and Alternaria alternata. In unspoiled samples, the genera found were Penicillium, Cladosporium, Rhizopus, Aspergillus and Phoma. Only three of the 126 samples failed to meet the required microbiological standards because they were found to contain faecal streptococci.
