Modeling interspecific competition of the microbial community during anaerobic digestion based on cellular automata and ADM1

open access: yesWater Science and Technology, 2021
Interspecific competition for substrate and space gives rise to considerable variation in biomass distribution within the microbial community. To study microbial community in depth, we used several research methods as sampling and analytical measurements,

Engineering Acetogenic Bacteria for Efficient One-Carbon Utilization

open access: yesFrontiers in Microbiology, 2022
C1 gases, including carbon dioxide (CO2) and carbon monoxide (CO), are major contributors to climate crisis. Numerous studies have been conducted to fix and recycle C1 gases in order to solve this problem.

Careful CO Addition Enhances Autotrophic d-Lactate Formation With Engineered <i>Acetobacterium woodii</i>. [PDF]

open access: yesEng Life Sci
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,

Adaptive Laboratory Evolution of Eubacterium limosum ATCC 8486 on Carbon Monoxide

open access: yesFrontiers in Microbiology, 2020
Acetogens are naturally capable of metabolizing carbon monoxide (CO), a component of synthesis gas (syngas), for autotrophic growth in order to produce biomass and metabolites such as acetyl-CoA via the Wood–Ljungdahl pathway.

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii. [PDF]

open access: yesMicrob Biotechnol
Microbial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.

Acetate Production from Syngas Produced from Lignocellulosic Biomass Materials along with Gaseous Fermentation of the Syngas: A Review

open access: yesMicroorganisms, 2023
Biotransformation of lignocellulose-derived synthetic gas (syngas) into acetic acid is a promising way of creating biochemicals from lignocellulosic waste materials.

Adaptive laboratory evolution of a thermophile toward a reduced growth temperature optimum

open access: yesFrontiers in Microbiology, 2023
Thermophily is an ancient trait among microorganisms. The molecular principles to sustain high temperatures, however, are often described as adaptations, somewhat implying that they evolved from a non-thermophilic background and that thermophiles, i.e ...

Methanogen Levels Are Significantly Associated with Fecal Microbiota Composition and Alpha Diversity in Healthy Adults and Irritable Bowel Syndrome Patients

open access: yesMicrobiology Spectrum, 2022
Hydrogenotrophic microbes, primarily including the three functional groups methanogens, sulfate-reducing bacteria, and reductive acetogens, use hydrogen as an energy source and play an important role in maintaining the hydrogen balance in gut ecosystems.

Pathway engineering and synthetic biology using acetogens [PDF]

open access: yes, 2012
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
