Abstract: The methods of extracting trehalose from S.boulardii was preliminarily studied in this experiment. Through the contrast between three kinds of extractant and using single and complex treatment,grope the best way to extract trehalose in S.boulardii: extractant is 5% trichloroacetic acid, water bath at 100 ℃ and 30 min after 10 min ultrasonication. Extracting supernatant was hydrolytic and determined glucose with the biosensor and calculate the content of trehalose.

Key words: Saccharomyces boulardii; trehalose; extraction; determination; biosensor
