I can tell you that susceptibility to antibiotics and ability to form biofilms are not necessarily correlated in Pseudomonas aeruginosa. While some studies have shown that antibiotic-resistant strains of P. aeruginosa are more likely to form biofilms, susceptibility to antibiotics does not necessarily preclude the formation of biofilms. In fact, some studies have shown that even antibiotic-susceptible strains of P. aeruginosa can form robust biofilms under certain conditions. Therefore, it is possible that your strain of P. aeruginosa could form biofilms, even if it is susceptible to antibiotics. It is important to investigate the specific properties of your strain, such as its motility, adhesion, and quorum sensing abilities, to determine its potential for biofilm formation.
