Abstract excerpt
This study was conducted to investigate the ability of cryoprotective chemicals to induce phenotypic cryoadaptation in Lactobacillus delbrueckii ssp. bulgaricus CIP 101027T. Tolerance to negative temperature stress (freezing at -20 degrees C and thawing at 37 degrees C) was induced by pretreatment with Me(2)SO, glycerol, lactose, sucrose, and trehalose. Interestingly, Me(2)SO has a significantly greater...
