Abstract
State of the art on the valorisation of C1 carbon sources obtained either from natural or anthropogenic origins as a key challenge for the circular economy.
Highlights
Carbon must be previously bound to other elements, forming small or very large molecules to become metabolizable by the living beings
Life arose from the combination of small molecules such as hydrogen (H2), water (H2O), ammonia (NH3), hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), formaldehyde (H2CO) or hydrocyanic acid (HCN), within others
We currently have at our disposal a collection of more than 100 isolated anaerobic bacteria named acetogens that synthesize acetyl-CoA from CO or from CO2 plus H2 (Bengelsdorf et al, 2016; Takors et al, 2018; Mu€ller, 2019; Jin et al, 2020; Katsyv and Mu€ller, 2020; Lemaire et al, 2020; Bourgade et al, 2021)
Summary
Several of them contain a single carbon atom and form part of a group of molecules named as C1 compounds All these prebiotic small molecules still remain in the biosphere, and some of them are quite abundant and useful to support life, remaining many micro- and macroorganisms able to use them as carbon and/or energy sources. The aim of this editorial is to analyse the present and future prospects and the valorization of C1 carbon sources obtained either from natural or anthropogenic origin through microbial biotechnology as a key challenge for the ‘Green Deal’ and the circular economy.
