Abstract:
Mineral waters are those waters that have a variable content of
mineral salts, gases, mineral substances, radioactive elements, which confer
therapeutically properties to these waters. In the past, the name of mineral
water was given to all the underground or superficial waters that could have
been used for therapeutically causes. In the last years, mineral waters for
therapeutically means were named curative waters.
In our country there are many mineral water springs and around them
were set up important resorts. Mineral waters are basically natural factors in
indicated disease treatment. Mineral waters are: salt-iodated-bromide, salt
sulphur and springs for internal cure with slightly sulphur mineralized,
bicarbonated, sulphurated, sodium calcinated, saline. Doro-sodium iodated
bromide waters with gases release (light hydrocarbons such as methane) are
deep underground waters cu high concentration, explored by bore.
In this study we have done microbiological analyses for 3 samples of
mineral water from Harghita, Mureş and Timiş counties. For all analyses we
considered the Romanian legislation and the Europenian legislation.
For the water samples analyzed we used the Millipore filters. The
method we use is more selective and quickly. The culture media we used for
filter impregnation is agar with lactose and tergitol 7.
There were used impregnated pads with nutritive media (according to
ISO 9308).
The method we used - filtration method on a membrane (white filter
with green grid). The coliform lactose negative bacteria generate red
colonies on these culture media, and lactose positive bacteria, respectively E.
coli generate yellow colonies.
