Two mineral springs, called Banos and Banos de Abajo, have been studied in the Spa Alicun de las Torres (Granada). The total number of microorganisms present in the water was of 7.6 and 4x10(4)/mL, respectively, being the majority alive (79 and 85.5%). The number of viable heterotrophic and oligotrophic bacteria, at 22 degrees C and 37 degrees C, was lower than 100 cfu/mL. The strains of the heterotrophic bacteria isolated predominantly correspond to fermenters and non-fermenters Gram-negative bacilli, belonging to the Class Gammaproteobacteria (54.5%) and in smaller proportion to Gram-positive bacilli (29.1%) and cocci (16.4%). The most common identified species were: Aeromonas hydrophila in the Banos de Abajo spring, and Neudomonas putida in the Banos spring. Neither Faecal indicators nor pathogenic microorganisms were found. On the other hand, ammonifying, proteolytic, amylolytic, halophilic bacteria as well as fungi were detected in 100 mL of water. The microbial mats of Banos de Abajo and Eucaliptos springs were studied as well. Both mats consist of an association of filamentous cyanobacteria (Oscillatoria, Pseudanabaena, Lyngbya), sphaeric cyanobacteria (Cyanothece, Synechocystis), diatoms (Cymbella, Fragilaria, Navicula, Nitzchia) and green algi (Cosmarium).
