Abstract :
[en] Sugar beet leaves were used as source of lyase in a biocatalytic process for the production of C6-aldehydes. Their hydroperoxide lyase activity was revealed important. The optimum values of pH and temperature for reactions were respectively 6.7 and 22 °C. A simple and fast process providing high molar conversion of hydroperoxides to aldehydes is proposed. The yield of the main product cis-3-hexenal reached 80% after only 2 min and was stabilised by acidifying the reaction medium to pH 2.
