| 摘 要： | 在植物乳杆菌对数期后期，高温（43—47℃）、低温（15—25℃）及10-30g/L NaCl等应激处理60min均可使植物乳杆菌耐热性和耐酸性得到较大的提高。其中，尤以高温应激45℃应激处理效果最好，细胞耐热残存率和耐酸残存率较对照分别提高124％和56．8％。

| Abstract: | In the later period of Lactobacillns planturam＇s logarithmic phase, the Lactobacillus planturam＇s heat and acid tolerance could be greatly enhanced by high temperature （43 -47 ℃ for 60 min）, or low temperature （ 15 - 25 ℃ for 60 min） or NaCl （ 10 - 30 g/L for 60 min） shock,especially when the temperature was at 45 ℃ ,where the cell＇s heat and acid survival were improved 124% and 56.8% in contrast with the control, respectively. |
