| Abstract: |
| By using the determination of single diathesis,the optical mediums of flask fermentation to dextran that separated from a strain of Leuoconostoc mesenteroides in Minyang Sugar-mill are obtained.It showed that the suitable mediums are:sucrose 10%,(NH4)2HPO4 0.6%,KH2PO4 0.1%, MgSO4 0.1%,yeast extract 0.4%,MnCl2·4H2O 0.0003%,ZnSO4·7H2O 0.0005%,FeSO4·7H2O 0.005% and CaCl2·2H2O 0.002%. |
| Key words: dextran mediums Leuoconostoc mesenteroides |
