The enhancement or induction of the protein synthesis was clearly observed in cells ofL. oenos labeled with35S for five proteins during heat shock at 42°C and acid shock at pH 3. Furthermore, no stress protein was induced after exposure ofL. oenos to ethanol shock 10% (v/v). Moreover, survival ofL. oenos in wine and ability to perform alolactic fermentation was improved after direct inoculation when cells were pretreated at 42°C.
