Batch Microbiological Reactors: Bioreactors Computational Design Structures, proffers the essential knowledge for the Mathematical description and Computational Analysis of microorganisms-utilizing Industrial Bioreactors, and develops for such bioreactors the related computational design structures for photolytic and non-photolytic, and Single-phase and Multiphase microbial reactions based on the underlying Microbiological Sciences. Specifically, Suspended Microbes Bioreactors, and Fluidized Immobilized Microbes-Carrier-Bed Bioreactors are the focus of analysis. The Computational Design Structures are developed through three critical innovative concepts: Unique Analysis of Diffusion Layers, "Composited" Reactions Mechanisms Kinetics, and Point Sinks Sources Ising Structures, and strictly for demonstration of Numerical Solutions use mostly Euler s Methods and Volterra Integral Equations that makes explicit the dynamic interactions between the design equations.Bioreactor Engineers should find Batch Microbiological Reactors Designs much useful aided with immediate-use facility in the provisioning of the Composited Reactions Mass Action Kinetics embodying the fundamental Point Sinks Sources conceptual design and the well-accepted growth"
