B. arsenicus MTCC 4380 was immobilized on the surface of NL/MnFe2O4 composite.
Immobilized bacterial cells were used for bioremediation arsenic from wastewater.
Non-linear regression analysis was employed to identify the best-fit kinetic model.
Different error functions were used to determine the best-fit kinetic.
Mechanistic and thermodynamic modelling were done.
