Citrobacter Telavivensis Fermentation Yields for 1,3-PDO, Ethanol, and H2 from Glycerol

Inés Ochoa-Arizu published a dataset on figshare in April 2026 detailing batch fermentation yields from glycerol using an extremophile bacterium. The data likely contains optimal molar yields for hydrogen (0.94 mol/mol-glycerol), 1,3-propanediol (0.66 mol/mol-glycerol), and ethanol (1 mol/mol-glycerol) under varying glycerol concentrations and temperatures. The study focuses on the metabolic conversion capabilities of Citrobacter telavivensis T1.2D-1, isolated from the Iberian Pyrite Belt.

Use Cases

• Modeling metabolic competition between 1,3-PDO/H2 and ethanol production based on glycerol concentration.
• Optimizing bioreactor conditions for biohydrogen yield based on the reported 0.94 mol/mol-glycerol optimum.
• Benchmarking genetic engineering targets based on the described dha, pdu, hyc, and fdhF operons.
• Assessing the industrial potential of glycerol waste streams for co-production of multiple chemicals.

Strengths

• Reports specific molar yields (e.g., 0.94 mol H2/mol-glycerol) from controlled batch fermentations.
• Includes genomic analysis confirming specific operons (dha, pdu, hyc, fdhF) responsible for synthesis.
• Provides antibiotic sensitivity profiling to support future genetic modification work.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (674.8 KB), indicating limited scope.
