This paper investigates the heat and mass transfer in the bioconvective flow of non-Newtonian Carreau nanofluid over a nonlinear elongated surface. Further, the magnetic effects, activation energy, and porosity impacts are considered. This study has many engineering applications; to name a few, biofuels, water treatment plants, and oil recovery, particularly in advanced microbial enhanced oil recovery (MEOR) technologies. The current physical problem is modelled by a set of nonlinear partial differential equations with suitable boundary conditions which are transformed to ordinary differential equations via similarity transformations. The resulting equations are numerically solved by bvp5c, MATLAB’s computational solver. The effects of several significant parameters on heat and mass transfer are discussed and explored through graphs and tables. The temperature of the fluid enhances with an upsurge in values of magnetic parameter. The fluid velocity grows with the porosity parameter and the Weissenberg number.
