Immobilization induces alterations in the outer membrane protein pattern of Yersinia ruckeri

We compared the outer membrane protein (OMP) pattern of 2-day-old immobilized Yersinia ruckeri cells (IC) with that of early (FC24) and late (FC48) stationary-phase planktonic counterparts. Fifty-five OMPs were identified. Principal component analysis discriminated between the protein maps of FC and IC. Some OMPs involved in bacterial adaptation were accumulated by both FC48 and IC but the expression of other proteins was controlled by the sessile mode of growth.
