Abstract
The autochthonous and alocthonous microbiota of the natural mineral water of Villavieja Spa have been studied. The total number of microorganisms in the water was of 4.7 x104/mL and the number of heterotrophic and oligotrophic viable bacteria was 103 cfu/mL. Neither faecal indicators nor pathogenic microorganisms were found in 250 mL of water. The autochthonous microbiota mostly belongs to Gram‐negative bacilli, from the Phylum Proteobacteria (64.4%) and in smaller percentage to the Gram‐positive bacilli (24.4%) and cocci (6.7%). The most frequently found species were Pseudomonas pseudoalcaligenes (15.5%) and Leifsonia aquatica (13.3%). Moreover ammonifying, proteolytic, amylolytic and sulphato‐reducted bacteria have been detected in 100 mL of water, all of them involved in self‐purification process of water.
