Biofilm formation dominated by sophisticated social behaviors in Myxococcus xanthus

Abstract:

Myxococcus xanthus is a Gram-negative soil bacterium capable of performing sophisticated cellular behaviors and growing one of the most intricate bacterial single-species biofilms in nature. During the process of biofilm formation, social behaviors of M. xanthus cells dominate key steps of the biofilm establishment, e.g., cellular motility on solid surface, predatory behavior by the grouped cells, kin recognition in the community, fruiting body development, myxospore differentiation, and programmed cell death. This review introduces the recent research progress about the M. xanthus biofilms.

Key words:Myxococcus xanthus, biofilm, cellular behavior, sociality
