Genotypic and phenotypic metabolic characterization of <i>Salmonella</i> Oranienburg isolated from sediment and river water

Of the 190 carbon sources evaluated using phenotypic microarrays, 61 showed high utilization efficiency based on the combined behavior of the λ, μ, and A parameters. Esters showed consistently high performance across all metabolic curve components, whereas fatty acids, carbohydrates, carboxylic acids, and amino acids displayed more heterogeneous responses.

In contrast, amines, amides, alcohols, and polymers generally showed lower utilization. The λ component showed the greatest variability among carbon source groups. Approximately 46.50% of gene occurrences were associated with metabolic functions across the 66 genomes, mainly carbohydrate and amino acid metabolism, energy production and conversion, and membrane-associated processes.
