Isotopic Bioinorganic Chemistry of Chemoautotrophs as a Predictor-Regulator for Formation of Metal Deposits and Factor of Weathering by Gradov OV in MAOPS- Lupine Publishers
The role of chemoautotrophs / lithotrophs in the formation of deposits
and weathering is almost universally known, however, the results of this
biogeochemical activity and mass transfer mediated by chemoautotrophs
are radically different depending on the ionic composition of the
medium, the salt conductivity effects and the Purbe diagram of the
corresponding conditions of this activity, as well as a number of other
physico-chemical Characteristics often not considered as impact factors
(for simplifying models). Biogeochemical representations of the early
period on which models and kinetic approaches to the analysis of similar
processes were based are, by most criteria, phenomenological and
"empirical", but do not reveal the essence of the processes occurring on
the border of the medium processed by microorganisms and the surface of
chemoautotrophs as active agents, that process this medium. Meanwhile,
from the point of view of biochemical physics (and, in particular,
biological kinetics), the mechanisms realized at the interface or in its
diffusion neighborhood are decisive in such cases, since the entry of
matter into "microreactor" compartments of biological origin and
aggregation with biomineralization, as a rule, occur mediated by the
surface of the biomembrane.
