Isotopic Bioinorganic Chemistry of Chemoautotrophs as a Predictor-Regulator for Formation of Metal Deposits and Factor of Weathering
Journal Title: Modern Approaches in Oceanography and Petrochemical Sciences - Year 2018, Vol 1, Issue 1
Abstract
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.
