The autochthon and alocthon microbiota of the mineral water of the Villa de Olmedo Spa have been studied. The total number of microorganisms in the water was of 4.5 x103/mL and the number of heterotrophic viable bacteria was lower than 5 cfu/mL. Neither faecal indicators nor pathogenic microorganisms were found; therefore these waters comply with the Spanish regulations on drinking water. The autochthon microbiota mostly belongs to Gram negative bacilli, from the Class Gammaproteobacteria (68.5%) and in smaller percentage to the Gram positive cocci (14.3%). The most frequently found species was Pseudomonas stutzeri. Moreover ammonifying, nitrifiying, proteolytic and amylolytic bacteria have been detected in 100 mL of water, all of them involved in self-purification process of water.
