| Abstract: | This paper describes the separation process of a new fermentation defoamer lard oil. By the optimum technique of emulsification combined with natural crystallization, liquefied lard at room temperature is separated from fresh lard with a high melting point. The lard oil can be used as on antibiotic fermentation defoamer to substitute edible bean oil. When it is applied in the fermentation test of rifamycin, the titer of rifamycin increases more than 15% compared with the old fermentation defoamer. |
