Thermotoga maritima is an anaerobic hyperthermophilic bacterium known for its high amounts of hydrogen (H-2) production. In the current study, the kinetic modeling was applied on the engineered strains of T. maritima that surpassed the natural H(2 )production limit. The study generated a kinetic model explaining H(2 )overproduction and predicted a continuous fermentation system. A Leudking-Piret equation-based model predicted that H(2 )production by Tma200 (0.217 mol-H-2 g(-1)-biomass) and Tma100 (0.147 mol-H(2 )g(-1)-biomass) were higher than wild type (0.096 mol-H-2 g(-1)-biomass) with reduced rates of maltose utilization. Sensitivity analysis confirmed satisfactory fitting of the experimental data. The slow growth rates of Tma200 (0.550 h(-1)) and Tma100 (0.495 h(-1)) are compared with the wild type (0.663 h(-1)). A higher maintenance energy along with growth and non-growth H-2 coefficients corroborate the higher H-2 productivity of the engineered strains. The modeled data established a continuous fermentation system for the sustainable H-2 production. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
