D-amino acids trigger biofilm disassembly
WebApr 14, 2011 · The Bacillus subtilis biofilm matrix harbours a functionally important amyloid fibre network composed of the protein TasA. Previous studies showed that the protein TapA (formerly YqxM) plays roles in TasA fibre formation and disassembly. In this issue, Romero et al., 2011 show that TapA is a component of the fibre and links it to the peptidoglycan. . … 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 …
