The ultimate purpose of present article is to investigate the heat, mass and motile microorganisms transfer rates in the convective stretched flow of Maxwell fluid consisting of nanoparticles and gyrotactic microorganisms. Magneto nanofluid in presence of mixed convection and stratification is considered. Concept of microorganisms is utilized just to stabilize the suspended nanoparticles through bioconvection which has been induced by combined effects of buoyancy forces and magnetic field. Further interesting aspects of Brownian motion, thermophoresis and stratification are examined. Convergent series solutions for the obtained nonlinear differential systems are derived. Impacts of different emerging parameters on velocity, temperature, concentration and motile microorganisms density are addressed through graphs. Numerical values for the local Nusselt, Sherwood and density number of motile microorganisms are computed and analyzed. It is observed that thermal, concentration and motile density stratification parameters result in the reduction of temperature, concentration and motile microorganisms density distributions, respectively.
