Title:
PREPARATION METHOD AND USE METHOD FOR HEAVY OIL VISCOSITY REDUCTION AND DEGRADATION MIXED MICROBIAL INOCULUM
Document Type and Number:
WIPO Patent Application WO/2021/077888
Kind Code:
A1
Abstract:
The present invention provides a preparation method and a use method for a heavy oil viscosity reduction and degradation mixed microbial inoculum. The mixed microbial inoculum comprises Acinetobacter sp. strain ZX-15, Achromobacter pulmonis strain PI3-03, Acinetobacter sp. strain RS206 and hrobactrum anthropi strain CON21, the four strains are obtained by manual screening, the former two strains are high-efficiency petroleum hydrocarbon degradation bacteria, and the latter two strains are high-efficiency heavy oil viscosity reduction bacteria. The heavy oil viscosity reduction and degradation mixed microbial inoculum has a high degradation efficiency for the heavy oil, has a good viscosity reduction effect, and has a good use prospect in environmental governance.
