This study analyzes the thermal instability in the Casson nanofluid suspended with aerobic microorganisms. Flow governing equations are modeled by incorporating the effects of Brownian motion, solutal concentration, and thermophoretic diffusion. Normal mode analysis is performed to discuss the stability of the fluidic system. The obtained eigenvalue problem is solved by employing the weighted residual Galerkin method. Further, the effects of flow governing parameters such as solutal Rayleigh number, bioconvection Rayleigh number, Dufour parameter, porosity, and Solutal parameter on the stability of the fluidic system are discussed graphically. It is concluded from the study that Casson nanoliquid delays the onset of bioconvection.
