•Bio convective Oblique flow of MHD Oldroyd-B fluid is analyzed.•Suction/Injection phenomena with zero heat and mass flux across the surface are incorporated.•Mass flux and local motile density diminish with thermophoresis parameter.•Local motile density enhances with Peclet number and Bio convection Lewis number. In recent research, it is worth mentioning that bioconvection usage has shown significant promise for environmentally friendly, sustainable “green” fuel cell technologies. In this context, the present problem definitely gives a boost to a deeper analysis of the Oldroyd-B fluid model in the presence of gyrotactic microorganisms. This study analyses oblique Oldroyd-B fluid with mixed convection on an elastic surface with interactive properties and gyrotactic microorganisms under the influence of suction/injection with zero heat and mass. The principal physical model is converted in a nonlinear system of ODEs employing proper similarity equations. The impact of all relative physical constrictions on velocity, temperature, concentration, and volume fraction of gyrotactic microorganisms is expressed geometrically. Physical scales like skin friction measurements, heat transfer rate, and mass transfer rate at the surface are calculated numerically.
