Gompertz Equation’s First and Second Derivatives for Kinetics Analysis of Batch Dark Fermentation on Bio-Hydrogen Production

Based on results of different works carried out under the project of hydrogen and sustainable energies of the Department of Energy and the perspective shown by Bergues et al [6], concerning the presentation and interpretation of results obtained by Aleman [21], Sandoval and Yanez [10] and Morales and Argueta [22]; it is established a rigorous method for the analysis of the results obtained using as a model the Gompertz equation, and its first and second derivatives as indicators, that focuses on dark fermentation bio-hydrogen production, from the perspective of the conversion of the product –i.e., not of reagents–, for purposes of its maximization and operation control.
