Sulphur is the fourth major essential nutrient element, after nitrogen, phosphorus and potassium, involved in biogeochemical cycles in nature. Sulphur is essential in all organisms because it is an integral part of major metabolic compounds, such as amino acids (methionine and cysteine), and it is an active component of numerous co-factors and prosthetic groups (Fe–S clusters, sulpholipids, glucosinolates, vitamins, etc), which are involved in metabolic processes of organisms. Medical research appears to confirm the validity of the use of sulphurous spring waters as therapeutical and preventive remedies for a large variety of diseases. In order to evaluate the quality of sulphurous water, samples have been taken of the Sulphurous Springs in Jibou. The objectives of this study were to determine physical and chemical properties (pH, electrical conductivity, salinity, redox potential) of some sulphurous water samples of Jibou area, and also to determine the microbiota involved in S biogeochemical cycle. The physical analysis showed that the sulphurous water of Jibou falls within the very weakly acidic reaction class, and the salinity was 0.2% in all samples. The aerobic heterotrophic bacteria show a maximum value in the sample 4 (2630x103 bacteria/ml). The microbial sulphurous community was detected in all water samples. This information should improve our understanding on adaptation mechanisms of bacteria involved in the sulphur cycle in correlation with physical-chemical parameters.
