Influence of temperature, pH and NaCl concentration on the maximal growth rate of Brochothrix thermosphacta and a bioprotective bacteria Lactococcus piscium CNCM I-4031

► Effect of pH, temperature and NaCl on Lactococcus piscium has been modelled. ► Same work was performed on Brochothrix thermosphacta and data validated in shrimp. ► Cardinal values were closed except NaClmax (3 times higher for B. thermosphacta). ► B. thermosphacta grew faster in shrimp than L. piscium. ► Bioprotective effect of L. piscium is not due to a better adaptation to shrimp matrix.
