|
This study was performed to investigate the effects of Lycii fructus extracts on the growth and physiology of S. cerevisae D71, L. casei KCTC 3165, and E. coli DH5. When Lycii fructus was added into solid culture media, the growth of S. cerevisea D71 and L. casei KCTC 3165 was increased, whereas that of E. coli DH5 was somewhat decreased. The growth of S. cerevisiea D71 and L. casei KCTC 3165 were much promoted in the culture media including methanol extract of 1.0% and 1.5%, respectively. E. coli DH5 was changed its morphology not only in 10% Lycii fructus juice but also 1.0% methanol and chloroform extract of Lycii fructus. Its size in those growth condition was eight times longer than that of the normal E. coli DH5. It was elucidated that elongation phenomenan of E. coli DH5 was also appeared by adding 0.135% of Na^+, K^+, and the mixture of Na^+ and K^+.
