J. Guzzo et al., INDUCTION OF STRESS PROTEINS IN LEUCONOSTOC-OENOS TO PERFORM DIRECT INOCULATION OF WINE, Biotechnology letters, 16(11), 1994, pp. 1189-1194
The enhancement or induction of the protein synthesis was clearly obse
rved in cells of L. oenos labeled with S-35 for five proteins during h
eat shock at 42 degrees C and acid shock at pH 3. Furthermore, no stre
ss protein was induced after exposure of L. oenos to ethanol shock 10%
(v/v). Moreover, survival of L. oenos in wine and ability to perform
malolactic fermentation was improved after direct inoculation when cel
ls were pretreated at 42 degrees C.
