Colonies were circular, bulgy, opaque, moist and white, with a 1-2 mm diameter. Its sequence showed 97.46% and96.91% homology with Sporolactobacillus vineae SL153 T and S. putidus QC81-06 T, respectively. Sporolactobacillus GD201215 uses glucose, fructose and sucrose to produce acid, and metabolizes sodium citrate to generate CO_2 which is responsible for swelling of fruit jelly. It grew anaerobically in GYP broth at 37 ℃, p H 3.5-7.0, with 0-2%(w/v) Na Cl, and could be killed by heating at 71 ℃ for above 5 min.展开更多
