Comparison of RML activities between control group and SLs addition group. a Extracellular activity. b Intracellular activity. c Intracellular activity proportion (*: 0.01 < P ≤ 0.05; **: P ≤ 0.01) When the intracellular activity proportion was calculated, the units of intracellular and extracellular enzyme activity had been normalized into units in the whole fermentation broth
