Perspectives for Advancing Biotechnological Succinic Acid Production
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

Oxidation of lactate under anaerobic dark fermentative conditions poses an energetic problem. The redox potential of the lactate/pyruvate couple is too electropositive to reduce the physiological electron carriers NAD(P)+ or ferredoxin.

Emerging Technologies for Biobutanol Production via Syngas Fermentation
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

We tested whether anaerobic digesters could operate at lower temperatures without losing methane production. Pilot‐scale reactors were run at 48°C or 55°C. Methane yields and gas quality were similar. Lower temperatures reduced volatile fatty acids and supported more diverse microbial communities.

Pathway engineering and synthetic biology using acetogens [PDF]
Acetogenic anaerobic bacteria are defined as organisms employing the Wood–Ljungdahl pathway to synthesize acetyl‐CoA from CO2 or CO. Their autotrophic mode of metabolism offers the biotechnological chance to combine use of abundantly available substrates with reduction of greenhouse gases.

Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Careful CO Addition Enhances Autotrophic d‐Lactate Formation With Engineered Acetobacterium woodii
ABSTRACT The acetogen A. woodii efficiently converts CO2 and H2 to acetate. Metabolic engineering enabled the autotrophic production of non‐native products, for example, d‐lactate from CO2 by overexpression of d‐lactate dehydrogenase from Leuconostoc mesenteroides and knockout of the native lactate dehydrogenase. During gas fermentation with acetogens,
