采用Bioscreen分析仪测定了24株从真空包装熟制环形香肠中分离的乳酸菌在NaNO 2和NaCl溶液中的生长情况。NaNO_2在50和100 mg/l时对乳酸菌生长的影响很有限，但在400 mg/l时有明显的抑制作用，1-2%（w/v）的NaCl对乳酸菌的生长有促进作用，而3%（w/v）以上的NaCl对乳酸菌的生长有明显的抑制作用。明串珠菌分离株似乎是更敏感的亚硝酸钠和氯化钠比同型发酵乳酸杆菌菌株。在同型发酵乳酸杆菌中，类似弯曲乳酸杆菌的菌株比类似清酒乳酸杆菌的菌株对NaCl更敏感。
The effect of NaNO2 and NaCl on the growth of 24 lactic acid bacteria strains isolated from vacuum-packed cooked ring sausages were examined by analyzing different growth parameters with Bioscreen. NaNO2 had a very limited effect on the growth of lactic acid bacteria at 50 and 100 mg/l but at 400 mg/l a more pronounced inhibitory effect was found. Bacterial growth was enhanced by 1–2% (w/v) of added NaCl, while NaCl concentrations above 3% (w/v) had a clear inhibitory effect. Leuconostoc isolates seemed to be more sensitive to sodium nitrite and sodium chloride than homofermentative lactobacilli strains. Among homofermentative lactobacilli, the strains resembling Lactobacillus curvatus were more sensitive to NaCl than those resembling Lactobacillus sake.
