Abstract
GroESL-overproducing Lactobacillus paracasei NFBC 338 was dried, and its viability was compared with that of controls. Spray- and freeze-dried cultures overproducing GroESL exhibited approximately 10-fold and 2-fold better survival, respectively, demonstrating the importance of GroESL in stress tolerance, which can be exploited to enhance the technological performance of sensitive probiotic cultures.
摘要
过量表达GroESL的副干酪乳杆菌NFBC 338被干燥，并将其活力与对照进行比较。过量表达GroESL的喷雾干燥和冷冻干燥培养物的存活率分别提高了约10倍和2倍，这表明GroESL在应激耐受性方面的重要性，可利用这一点来提高敏感益生菌培养物的技术性能。
