Decision tree to classify bacteria by genus based on enzyme activities measured after growth in BPS supplemented with 0.5% glucose. Example for interpretation: 58 strains fall in Node 8 which is defined as strains where the BcAT activity is higher than 0.014 and the esterase activity is lower than 0.008. Within that node, roughly 90% of all strains are lactococci (error rate with this prediction is lower than 10%).
