Examining mixotrophic fermentation in fed‐batch mode for C1‐gas valorization

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 7, Page 1453-1462, July 2025.
Abstract BACKGROUND C1‐gases like CO and CO2, significant contributors to climate change, offer the potential for sustainable bioconversion into valuable products. The study explored mixotrophic fermentation using C1‐gases in fed‐batch mode to improve the production of target compounds, focusing on Clostridium aceticum and Clostridium carboxidivorans ...

Assessment of Chemical Inhibitor Addition to Improve the Gas Production from Biowaste [PDF]

, 2019
The coexistence of sulphate-reducing bacteria and methanogenic archaea in the reactors during the anaerobic digestion from sulphate-containing waste could favor the accumulation of sulfide on the biogas, and therefore reduce its quality.
