Transitional Surfaceomics: Identification of Planococcus halocryophilus Surface-Associated Proteins During Optimal and Sub-Zero Growth

During sub-zero (cryophilic) growth, nodular features appear on the cell surface of Planococcus halocryophilus; however, the biochemical composition of these features as well as any cold-adaptive benefits they may offer are not understood. This study aimed to identify differences in the surfaceome of P. halocryophilus cells grown under optimal (24°C) and sub-zero (-5°C and -10°C) culture conditions, for the purpose of gaining insight into cold-adapted proteomic traits at the cell surface.
