    • Parametric Sensitivity of CSTBRs for Lactobacillus casei: Normalized Sensitivity Analysis 

      Das, Subhashis; Calay, Rajnish K; Chowdhury, Ranjana (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-18)
      In this paper, a sensitivity analysis of a continuous stirred tank bioreactor (CSTBR) was conducted to determine a parametrically sensitive regime. The growth of a lactic acid bacterium, namely, <i>Lactobacillus casei</i>, in a pH-controlled CSTBR was considered as a process model. Normalized objective sensitivities of the minimum pH were determined with respect to input parameters. A generalized ...

    • Product Inhibition of Biological Hydrogen Production in Batch Reactors 

      Das, Subhashis; Calay, Rajnish K; Chowdhury, Ranjana; Nath, kaustav; Eregno, Fasil (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-12)
      In this paper, the inhibitory effects of added hydrogen in reactor headspace on fermentative hydrogen production from acidogenesis of glucose by a bacterium, Clostridium acetobutylicum, was investigated experimentally in a batch reactor. It was observed that hydrogen itself became an acute inhibitor of hydrogen production if it accumulated excessively in the reactor headspace. A mathematical model ...
