Appropriate Chinese translation of “biofilm”

Abstract:

“Biofilm” refers to an aggregated bacterial film in which bacterial cells wrap themselves by secreting extracellular polymeric substances (EPS) after attaching to abiotic or biotic surfaces. The formation of a biofilm includes five stages:attachment, colonization, development, maturation, and active dispersal. A biofilm is a dynamic bacterial community with a complex structure and multiple functions, so the bacteria in a relatively stable microenvironment have stronger resistance to stress, which makes pathogens more difficult to be eliminated and promotes the survival and colonization of probiotics in the host. At present, there is confusion in the Chinese translation of "biofilm", and no clear conclusion as to which usage is more appropriate. In view of this problem, this paper analyzed the formation process, physiological functions, and current usage of "biofilm", and finally determined the most appropriate Chinese translation of this word.
