Areas of inhibition of L. monocytogenes growth on the surfaces of cheeses inoculated with complex consortium TR15 and defined microbial consortia.
|AI (8–2)||AI (18–8)||AI (28–18)|
AI = area of inhibition calculated between 2 days of ripening (t2−t1) according to the formula, AI = (t2 − t1)/2 × [(Ct2 + Ct1) − (Tt2 + Tt1)], with C = L. monocytogenes counts in the control cheese and T = L. monocytogenes counts in cheeses inoculated with consortia.
Cheese surfaces inoculated with control = commercial ripening culture; TR15 = complex consortium (rind suspension) and ABCD, ABC, ABD and ACD = defined consortia from identified isolates (A = six lactic acid bacteria, B = seven Gram-positive and catalase-positive bacteria, C = three Gram-negative and D = three yeasts). Numbers in bold fonts indicate the highest inhibition.
