En este sentido se aborda la metanogenesis (los aceptores electronicos Anales pueden ser: CO2, metanol, formiato, acetato, entre otros), la reduccion del SO42-
, y la reduccion del CO2 a acetato, y del NO3- a NO2- (Madigan et al.

The mean values of pH, Na+, and SO42-
are within the permissible limits of WHO standards.
However, several kinetic factors (hydration of Mg2+ ions in seawater, high ionic strength of seawater, relative efficiency of aragonite and high-Mg calcite precipitation, inhibition effects of SO42-
ions) mitigate its formation (Scholle & Ulmer-Scholle 2003).

It was concluded from the study that majority of physico-chemical parameters including pH, EC, TDS, Cl-, SO42-
, Na+, K+, Ca2+ , Mg2+ , Ni, Mn, Cu, Zn, Co, As, were within the permissible limits of WHO and US EPA except NO 3- and PO 4 3-, which exceeded the permissible limits in 70% and 55.
The contents and change trends of NO3-, SO42-
, Ca, K, Fe, Cu and B analysis showed that cultivated soybean was closer to the semi-wild and quite different to common The annual average contents of NO3 Zn and B were significantly higher in salt-tolerant than contents of SO42-
, Ca, K, Mg, Fe, Mo and Mn were significantly lower than in common wild soybean (Table 2, P < 0.
The NO3- Cl- H2PO4- and SO42-
contents were determined by ion chromatography (DX-300 ion chromatographic system; AS4A-SC ion-exchange column CDM-II electrical conductivity detector mobile phase: Na2CO3/NaHCO3=1.
Also, they reflect the strong coordinating ability of NO3, Cl, Br, AcO and SO42-
anions, depending on the type of the anions.
Sources of CO2 of the waters are fresh carbonates, marine carbonate and metamorphic origin to the results of 13C; and sources of SO42-
of the waters are volcanic sulphur, petroleum-coal and sulphide in limestones to the results of 534S.
