This study identifies the regulatory mechanisms of nitrogenase in Vibrio natriegens, showing that NtrBC is not essential but important for timely expression, while NifA autoactivation suffices for nitrogenase gene expression.

This study compares the fermentative physiology of Vibrio natriegens and Escherichia coli, finding that V. natriegens is more sensitive to its acidic fermentation products due to lacking acid resistance genes.

The paper shows that bacterial quorum sensing optimizes carbon metabolism by regulating methionine and tetrahydrofolate synthesis, enhancing growth in changing glucose conditions.

The paper identifies adenine as a cross-fed metabolite between Rhodopseudomonas palustris and E. coli, revealing a purine salvage bottleneck mechanism.
