Department of Applied Chemistry, Faculty of Chemistry, University of the Basque Country, PO Box 1072, 20018 San Sebastián, Gipuzkoa, Spain Histidine decarboxylase activity has been investigated in 23 strains of lactic acid bacteria, belonging to Oenococcus oeni, Lactobacillus brevis and Lactobacillus spp., isolated during the cidermaking process at different stages of fermentation. After 14 days at 25 °C on a semisynthetic medium supplemented with L-histidine, 13 strains were histamine producers and six of these strains were selected to study the kinetics of growth and histamine production at different temperatures. The results showed that histamine accumulation was maximal at 25 °C after 10-15 days of growth. Comparison of growth and histamine level curves demonstrated a delay time of eight days between maximal growth and the highest histamine content of the cultures.
