ABSTRACT
The surface of Bacillus VMSDCM (accession no. HQ108109) has been characterized at various pH values of the experimental solution. The boundary values of conditional parameter were used to develop a mathematical six lumped stochastic model for studying the surface chemistry of the bacterium cells. The results of the model were statistically analyzed to understand the strength of the proposed model. The simulation of the model was performed in Turbo C++ interface. The convergence values of the model were recorded and all the asymptotic points were neglected. The optimum values of model were reiterated to identify the intermittent values of maximum number of active sites, concentration of hydrides and hydroxides of calcium and magnesium and difference between the theoretical and experimental count of active sites. The values of zeta potential indicated towards the ionization of negatively charged surface functional groups at higher values of pH. The results of the present investigation revealed the fact that changes in the values of conditional parameter (pH) may create a drift in design parameters of a batch or continuous column reactor, fabricated for biosorption-cum-bioaccumulation of metal ions (Ca2+ and Mg2+) across liquid phase.

Notes
* Biosorption-cum-bioaccumulation: It means passive adsorption of metal ions on the surface of bacterium cells followed by active uptake of metal ions inside the bacterium cells.
