Using different ways to break cell for releasing SAM were investigated, such as ultrasonic, Chemical infiltration and freeze-thaw.

The effects of oxygen supply on growth of Saccharomyces cerevisiae and S-adenosyl-L-methionine(SAM) formation were studied in 5 L fermentor.

S-adenosyl-L-methionine(s-adenosyl-L-methionine,as SAM),is important in the middle of metabolic body,has to methyl,to sulfur,such as to aminopropyl, homocysteine is,Taurine,Gu Gan-peptide,coenzyme A,and other important precursor substances.
