Effects of initial medium pH and gas flow rate on Clostridium ljungdahlii and Clostridium autoethanogenum in liquid batch, continuous gas fermentations were investigated. Synthesis gas components were supplied at varying flow rates (5, 7.5 and 10 mL/min) for C. ljungdahlii (pH 6.8 and 5.5) and C. autoethanogenum (pH 6.0).

Bioresource Technology, 2014
In this study, nanoparticles were used to enhance bioethanol production in syngas fermentation by Clostridium ljungdahlii. Six types of nanoparticles were tested: palladium on carbon, palladium on alumina, silica, hydroxyl-functionalized single-walled carbon nanotubes, alumina, and iron(III) oxide. Of these, silica nanoparticles at a concentration of 0.

Rediverting carbon flux in Clostridium ljungdahlii using CRISPR interference (CRISPRi)
Metabolic Engineering, 2018Clostridium ljungdahlii has emerged as an attractive candidate for the bioconversion of synthesis gas (CO, CO2, H2) to a variety of fuels and chemicals through the Wood-Ljungdahl pathway. However, metabolic engineering and pathway elucidation in this microbe is limited by the lack of genetic tools to downregulate target genes. To overcome this obstacle,

Clostridium ljungdahlii is a representative autotrophic gas-fermenting acetogen capable of converting CO2 and CO into biomass and multiple metabolites. The carbon fixation and conversion based on C. ljungdahlii have great potential for the sustainable production of bulk biochemicals and biofuels using industrial syngas and waste gases. With substantial

Clostridium ljungdahliifor production of biofuel from synthesis gas
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2016ABSTRACTLowering the redox potential of the growth medium is a critical step in the cultivation of obligate anaerobes for production of biofuels from synthesis gas. In this study, the simultaneous effects of reducing solutions (sodium sulfide and/or cysteine-HCl) and initial medium pH on the fermentation of synthesis gas using Clostridium ljungdahlii ...
