| Abstract: | Lacticbionic acid-producing strain was isolated from soil and identified that is Burkholderia cepacia. A lacticbionic acid -high producing mutant named as NTG-15-03 stain was bred by NTG. It was showed that the genetic property of this mutant was stable by pass-generation tests, Afterthat the fermentation condition was initially researched. The result showed that.the production of lacticbionic acid of NTG-15 -03 strain was 92.1g/L on the medium of lactose 10G; corn syrup1.0G; NaC1 0.05G; KH2PO4 0.1%; K2HPO4 0.1G ; MgSO4 0.05G ; pH 7.0. |
