MokhtarH. 1200941The production of two strains of lactic acid bacteria isolated from Tunisian fermented milk (Leben): Lactococcus lactis var. lactis (SLT6 and SLT10) was investigated in fed-batch process. The final biomass production after 8 h was upper than 1010 cells mL-1 for both strains. The strains present an important growth rate (0.95±0.03 h-1) and short generation time. The conversion yield (Yx/s) is 0.12 and 0.14 g g-1 for SLT6 and SLT10, respectively.The survival after freeze-drying is 22 and 37% for SLT6 and SLT10, respectively.]]>Achour, M., N. Mtimet, C.
