N-acylation of L-amino acids in aqueous media: Evaluation of the catalytic performances of Streptomyces ambofaciens aminoacylases.

N-acylated amino acids are widely used as surfactants and/or actives in cosmetics and household formulations. Their industrial production is based on the use of the Schotten-Baumann chemical and unselective reaction. Faced to the growing demand for greener production processes, selective enzymatic synthesis in more environment-friendly conditions starts to be considered as a potential alternative.

Enzymatic synthesis of geranyl acetate in packed bed reactor in supercritical carbon dioxide under various pressure-temperature conditions and reactor configurations.

Data in this paper describes the catalytic performances, expressed in terms of conversion %, of geraniol and acetic acid to geranyl acetate, using the immobilized lipase B from in packed bed reactors (PBR) using supercritical CO as a solvent. Readers will find data related to different Figures or equations of the article as well as supplementary data that will help to make the difference between flowrates of CO in a liquid state and corresponding flowrates of supercritical CO for various CO pressure and temperature combinations.
