Screening of Lactic Acid Bacteria Strains with Respiration Ability in the Present of Heme
Abstract:
25 strains of Lactic Acid Bacteria were selected to carry on aerobic cultivating test. It was found that LD33 and 1031 could undergo respiration in the present of heme. compared with the original strain cultivated under fermentative conditions , both its biomass and pH increased. After 45 days storaged at 4°C, the strain LD33 cultivated under fermentative condition was less than 10CFU/mL, while the viable cell count of strain cultivated under respiratory condition was remain 108 CFU/mL. Aerobic respiratory metabolism shift occurred in the early exponential growth was indicated by the growth curve and pH curve.
