D-amino acids trigger biofilm disassembly
WebBiofilms are the cause of 80% of microbial infections. Acinetobacter species have emerged as multi- and pan-drug-resistant bacteria and pose a great threat to human health. These act as nosocomial pathogens and form excellent biofilms, both on biotic and abiotic surfaces, leading to severe infections and diseases. Various methods have been developed for … WebApr 12, 2024 · Conversely, it has been described that a P. putida mutant in cbrB, which acts as a global regulator of the uptake and metabolism of certain amino acids, shows reduced swimming motility, presumably related to a chemotactic defect, and increased biofilm formation (Amador et al., 2010). Despite these data, it would be a mistake to deduce that ...
