Bacterial species detected in some bottled mineral waters sold in Italy.
A total of 51 samples from 32 different kinds of mineral water were examined to investigate their microbial facies in view of a possible relationship with ionic composition. No difference was found between mineral and oligomineral waters. The genera most represented were Pseudomonas, Flavobacterium and Alcaligenes; only rarely could members of these genera be assigned precisely to a defined species, because many strains showed intermediate patterns. The authors suggest widening the microbiological examination of mineral waters and improving ecological and taxonomic knowledge of the autochthonous species in all processing phases in order to evaluate not only their compliance with the law, but also the variations imposed on microflora by different conditions related to container materials, time and temperature of storage.
