Abstract： |
The invention discloses a Duganella bacterium and its application. The Duganella bacterium is sp. B2 CGMCC No:2056. Culturing Duganella sp. B2 CGMCC No:2056 will get purple bacteriocin. The fermenting condition for the bacterial strain is: culturing 24-60 h under 4-28 DEG C. The fermenting culture medium contains in each liter: starch 10-20 g, ferrisulphas 0.01-0.05 g, potassium nitrate 0.8-1.2 g, dipotassium hydrogen phosphate 0.5-1 g, and magnesium sulfate 0.5-1 g. The pH value of the fermenting culture medium is 6-9. The purple bacteriocin from the bacterial strain is a natural product, and free from any hidden harm due to artificial pigment. Tests show that the purple bacteriocin is of good biologic activity, will generate no side effect on animal bodies, and can be widely used in such fields as medicine and industries, etc. |
