Aromatic carboxylic acids are readily obtained from lignin in biomass processing facilities. However, efficient technologies for lignin valorization are missing. In this work, a microbial screening was conducted to find versatile biocatalysts capable of transforming several benzoic acids structurally related to lignin, employing vanillic acid as model(More)
Natural and modified nucleoside-5′-monophosphates and their precursors are valuable compounds widely used in biochemical studies. Bacterial nonspecific acid phosphatases (NSAPs) are a group of enzymes involved in the hydrolysis of phosphoester bonds, and some of them exhibit phosphotransferase activity. NSAP containing Enterobacter aerogenes and Raoultella(More)
Deaminases are enzymes that catalyze the hydrolysis of amino groups of nucleosides or their bases. Because these enzymes play important roles in nucleotide metabolism, they are relevant targets in anticancer and antibacterial therapies. Mammalian deaminases are commercially available but the use of bacterial whole cells, especially as biocatalysts, is(More)
