The treatment of mineral water with silver allows to significantly extend its shelf life without deteriorating its organoleptic properties, which makes it possible to use mineral water away from the natural deposit and is critical for business and the end consumer. However, possible changes in the physiological properties of mineral waters when treated with silver have not been studied until now. We have carried out a preclinical double-blind randomized placebo-controlled, experimental study, during which the effect of treatment with silver sulfate at a dose of 0.02 mg / liter (according to the EAEU tR 044–2017 regulation) of natural mineral water of sulphate-hydrocarbonate calcium-sodium (Russia, Stavropol territory, deposit “Slavyanovskaya”, well No. 69 bis) for cellular metabolism, microcirculation and micro-lymphocyte when applied externally to the area of the inner surface of the forearm. A comparison of the effect on cell metabolism and microcirculation has been made for applications with native mineral water “Slavyanovskaya”, “Slavyanovskaya, enriched with silver sulfate” and placebo (tap water) after 30 minutes and after 24 hours. Number of patients: 15. Number of studies by location: 45. the results were monitored using the LAZMA St device. the study carried out simultaneous registration of diagnostic parameters of blood microcirculation, lymph microcirculation, as well as fluorescence amplitudes of coenzymes participating in oxidative metabolism - reduced nicotinamide adenine dinucleotide (NADH) and oxidized flavin adenine dinucleotide (FAD). It was revealed that the mineral water “Slavyanovskaya enriched with silver” differs in its physiological effect on cellular metabolism, microcirculation and micro-lymph flow from the physiological effect of the mineral water “Slavyanovskaya”, namely that, compared to “Slavyanovskaya”, the mineral water “Slavyanovskaya enriched with silver” has a more pronounced positive effect on cellular metabolism, metabolic reserves of the cell, promotes the activation of microcirculation and micro-lymphatic flow. Mineral water “Slavyanovskaya, enriched with silver” has a longer effect on cellular metabolism, microcirculation and micro-lymphatic flow than mineral water “Slavyanovskaya”. A statistically significant positive effect of cell metabolism activation was detected both 30 minutes and 24 hours after exposure. Thus, this method of processing mineral water with silver sulfate not only does not decrease its positive physiological effect, but also improves it, prolonging its action, which makes further use of silver preparations in the processing of mineral water justified.

The expansion of harmful cyanobacterial blooms is of worldwide concern as they have increased globally in frequency and intensity in recent decades. A cyanobacterial colony was found in a bottle of natural mineral water of a small water company in July 2012, which led to a further examination for a period of five months (July-November 2012) of both the bottled filtered water and the originating groundwater source (N. Greece) for the occurrence of Cyanobacteria. Cyanobacteria occurrence was monitored by microscopy and cyanospecific 16S rDNA amplification; potentially toxic species occurrence was screened by mcyA gene (known to take part in the MC-biosynthetic gene cluster) amplification. The highest abundance of cyanobacterial cells without the simultaneous presence of the mcyA gene, was measured in July, in contrast to October when the presence of cyanobacteria was only identified by tracing cyanospecific 16S rDNA and the mcyA gene region in the underground water source. The results of this small scale monitoring program indicate the potential existence of an emerging danger for human health in a relatively manageable product such as the bottled natural mineral water.

ABSTRACT Bacterial growth occurs in noncarbonated natural mineral waters a few days after filling and storage at room temperature, a phenomenon known for more than 40 years. Using the full-cycle rRNA approach, we monitored the development of the planktonic bacterial community in a noncarbonated natural mineral water after bottling. Seven 16S rRNA gene libraries, comprising 108 clones in total, were constructed from water samples taken at various days after bottling and from two different bottle sizes. Sequence analyses identified 11 operational taxonomic units (OTUs), all but one affiliated with the betaproteobacterial order Burkholderiales (6 OTUs) or the class Alphaproteobacteria (4 OTUs). Fluorescence in situ hybridization (FISH) was applied in combination with DAPI (4′,6′-diamidino-2-phenylindole) staining, viability staining, and microscopic counting to quantitatively monitor changes in bacterial community composition. A growth curve similar to that of a bacterium grown in a batch culture was recorded. In contrast to the current perception that Gammaproteobacteria are the most important bacterial components of natural mineral water in bottles, Betaproteobacteria dominated the growing bacterial community and accounted for 80 to 98% of all bacteria detected by FISH in the late-exponential and stationary-growth phases. Using previously published and newly designed genus-specific probes, members of the betaproteobacterial genera Hydrogenophaga, Aquabacterium, and Polaromonas were found to constitute a significant proportion of the bacterial flora (21 to 86% of all bacteria detected by FISH). For the first time, key genera responsible for bacterial growth in a natural mineral water were identified by applying molecular cultivation-independent techniques.
