Serratia sp. cause food losses and waste due to spoilage; it is noteworthy that they represent a dominant population in seafood. The main spoilage associated species comprise S. liquefaciens, grimesii, proteamaculans quinivorans, also known as liquefaciens-like strains. These are difficult discriminate since classical 16S rRNA gene-based sequences do not possess sufficient resolution. In this s...

This work proposes the design of β-keto esters as antibacterial compounds. The was based on structure autoinducer bacterial quorum sensing, N-(3-oxo-hexanoyl)-l-homoserine lactone (3-oxo-C6-HSL). Eight ester analogues were synthesised with good yields and spectroscopically characterised, showing that compounds only present in their tautomer form. We carried out a computational analysis reactivi...
