Abstract

Disclosed herein is a method of microbial enhanced oil recovery by changing microbial motility, including: subjecting a viable Glycocaulis strain and the alkane-degrading Dietzia strain to contact culture to enable the alkane-degrading Dietzia strain to have motility. This application also provides a method for microbial enhanced oil recovery, including: subjecting a viable Glycocaulis strain and the alkane-degrading Dietzia strain to contact culture to enable the alkane-degrading Dietzia strain to have motility; and injecting the contact culture mixture of the viable Glycocaulis strain and the alkane-degrading Dietzia strain to an oil well to perform microbial enhanced oil recovery.
