Recombinant formate dehydrogenase from the acetogen Clostridium carboxidivorans strain P7(T), expressed in Escherichia coli, shows particular activity towards NADH-dependent carbon dioxide reduction to formate due to the relative binding affinities of the substrates and products. The enzyme retains activity over 2 days at 4°C under oxic conditions.

Article Synopsis
  • To scale up bio-based building block production via CO and H fermentation, understanding the microbial response to bioreactor conditions is essential.
  • The study focuses on how various factors like gas pressures and feeding strategies influence the production of 1-hexanol using a modified Clostridium carboxidivorans strain.
  • Results showed that a combined approach of initial gas limitation followed by continuous gas feeding significantly enhanced 1-hexanol productivity and carbon selectivity, highlighting the potential for producing valuable chemicals beyond traditional outputs.

Metabolic Versatility of acetogens in syngas Fermentation: Responding to varying CO availability.

Bioresour Technol

CEB - Centre of Biological Engineering, University of Minho, Braga, Portugal; LABBELS - Associate Laboratory, Braga/Guimarães, Portugal.

Syngas fermentation using acetogenic bacteria offers a promising route for sustainable chemical production. However, gas-liquid mass transfer limitations and efficient co-utilization of CO and H pose significant challenges. This study investigated the kinetics of syngas conversion to acetate by Acetobacterium wieringae and Clostridium species in batch conditions under varying initial CO partial pressures (19 - 110 kPa).

Article Synopsis
  • There's increasing scientific interest in using oleaginous yeasts, like Rhodosporidium toruloides, for producing microbial oils that can serve as biofuels.
  • Due to high costs of traditional substrates, volatile fatty acids (VFAs), sourced from pollutants, are being explored as cheap alternatives.
  • In experiments, R. toruloides effectively used VFAs from the fermentation of syngas, achieving considerable lipid accumulation and suggesting new avenues for biofuel production from C1 gases.

This study compares carbon dioxide conversion in carbonate-fed microbial electrosynthesis (MES) cells operated at low (5.3), neutral (7) and high (8) pH levels and inoculated either with wild-type or bioaugmented mixed microbial populations. Two 100 mL (cathode volume) MES cells inoculated with anaerobic digester sludge were operated with a continuous supply of carbonate solution (5 g L as CO ).

Microbial community assemblage altered by coprecipitation of artificial humic substances and ferrihydrite: Implications for carbon fixation pathway transformation.

The suppression of soil carbon mineralization has been demonstrated to be effectively facilitated by carbon‑iron interactions, yet the specific mechanisms by which artificial humic substances (A-HS) coupled with ferrihydrite influence this process remain insufficiently explored. This study is to investigate how the A-HS, specifically artificial fulvic acid (A-FA) and artificial humic acid (A-HA), coupled with ferrihydrite, affect carbon mineralization under anaerobic system that simulates paddy flooding conditions. The object is to investigate trends in carbon emissions and to delineate microbial community structure and functional pathways.
