Influence of liquid-phase hydrogen on dark fermentation by Thermotoga neapolitana

Enhancing thermophilic dark fermentative hydrogen production at high glucose concentrations via bioaugmentation with Thermotoga neapolitana

“…Thus, the bioaugmentation with T. neapolitana directed the metabolic pathway towards acetate and lactate production. Previous reports on pure cultures of T. neapolitana have shown that acetate, lactate and alanine are the major soluble metabolites produced by T. neapolitana [41,56,57]. The direction of the metabolic pathway towards acetate production allows producing more H2 and seemed to be the case with the bioaugmented culture in this study.…”
