Abstract
The present application belongs to the field of bioengineering, and relates to an engineering strain, in particular to a pantoea that degrades vetiverol and application. The preservation number of the strain is CGMCC NO.30671. The pantoea that degrades vetiverol in the present application can convert vetiverol, an intermediate product in ambergris, into a friendly ambergris substance, and the degradation rate of vetiverol is above 65.99% within 72 h. The pantoea is used for fermentation of tobacco leaves, which is helpful to improve the quality of tobacco leaves and improve the sensory quality of cigarettes.
