Recherche de souches bactériennes dans les eaux minérales naturelles vendues dans la ville de Ain-Temouchent

Abstract

Natural mineral water is characterized by its richness in mineral salts and trace elements and especially by its microbiological quality which is free from pollution or contamination by pathogenic germs. The search for pathogenic germs in natural mineral water makes it possible to assess its microbiological state, it is for this purpose that our study was carried out on natural bottled mineral waters marketed and intended for human consumption in the city of Ain temouchent. We searched in the hygiene laboratory of the wilaya of AinTemouchent the presence of microbiological contamination in the waters included in our study based on parameters and indicator values of the good microbiological quality of drinking water human quoted in the official Algerian newspaper. Results obtained after analysis of coliforms, total germs, fecal streptococcus, Clostridium Sulfitoreducteurs and Pseudomonas show a total absence of contamination this allowed us to observe that the bacteriological quality of the natural bottled mineral waters included in our study is of good bacteriological quality
