This investigation includes the performance of the Couple Stress Nanofluid with microbial activity, activationenergy incorporation of thermal conductivity, heat generation, variable viscosity and other parameters.We used some suitable similarity transformations to convert the governing partial differential equationsand the initial boundary conditions of our model into the coupled structure of ordinary differentialequations and final boundary conditions. Furthermore, the Spectral Quasi Linearization Method (SQLM)was used to numerically solve these ordinary differential equations with boundary conditions, generatingthe reassuring impacts of various parameters taken in our model. The graphical representation for the flow,temperature, solute and microbial distribution was analyzed with activation energy, heat generation andother interesting parameters. The impact of variable viscosity and thermal conductivity with the Prandtlnumber for the local skin friction, Nusselt, Sherwood, and the microbial density numbers was included andreflects the favorable results. The comparison table is also included to validate our model. The rising valuesof the activation energy parameter enhances the solute and microbe profiles, while rising of bio-convectionRayleigh number and Reynolds numbers discriminates the heat profiles, but enhances the solute profile.The microbial profile of the model falls for the rising values of the microbe reaction parameter.
