AB  - The effect of mixed culture of <I>Leuconostoc mesenteroides </I>subsp. dextranicum and <I>Lactococcus lactis</I> subsp. lactis (prot<SUP>+</SUP>) was investigated to achieve an optimal production of carbone dioxide. Only the strain of <I>Leuconostoc mesentroides</I> can produce carbon dioxide from lactose and citrate in milk. The influence of the initial concentration ration between the 2 strains on growth, carbon dioxide, L-lactate, acetic acid production and citrate used was displayed. When the initial inoculum of <I>Lactococcus lactis</I> was 2.5 10<SUP>5</SUP> cfu mL <SUP>1</SUP>, the growth and evolved CO<SUB>2</SUB> by <I>Leuconostoc mesenteroides</I> (3&nbsp;10<SUP>7</SUP> cfu mL <SUP>1</SUP>) increased. Whereas, high inoculum of <I>Lactococcus lactis</I> induce a decrease of growth and CO<SUB>2</SUB> production by <I>Leuconostoc mesenteroides.</I> In mixed culture CO<SUB>2</SUB> production continued after growth stopped, a partial uncoupling can be observed between growth and CO<SUB>2</SUB> production. A shift of acetate production was observed in mixed culture and 25.6 mM was obtained, whereas 30.18 mM was obtained at the same time in pure culture of <I>Leuconostoc mesenteroides</I>.
