This work was carried out to determine the activity of enzymes involved in arginine metabolism in Lactobacillus plantarum isolated from wine and previously characterised at molecular level. The activity of the enzymes arginine deiminase and ornithine tran-scarbamylase was determined and citrulline and ornithine formed were analysed by HPLC analysis. Although the enzymatic activity was detected in all the strains analysed, a strong variability was observed between strains. Lactobacillus plantarum strain Lp60 is the strain with more possibilities to accumulate citrulline, precursor of the carcinogenic ethyl-carbamate, as showed by its high arginine deiminase activity and low ornithine transcarbamylase activity.
