Different abilities of biofilm formation are presented as the categories: −, non-adherent; +, weakly adherent; ++, moderately adherent; +++, strongly adherent. △CT is defined as the CT value of the target gene minus that of the reference rpoB gene. ^▲A50 referred to XAb50 while A53 referred to XAb53.
