Abstract
Burkholderia pseudomallei biofilms are resistant to antibiotics and immune responses, leading to persistent infections. This study aimed to investigate the metabolic profiles of B. pseudomallei in biofilms and the extracellular polymeric substances (EPS) produced during grown in LB or MVBM medium using Nuclear Magnetic Resonance (NMR) spectroscopy to identify key metabolites. The results revealed similar biofilm metabolites in both media. However, betaine was detected in LB, but not in the case of MVBM. Acetate was significantly higher in MVBM compared to that of LB. Pathway analysis revealed that betaine-producing B. pseudomallei biofilm in LB was associated with metabolism of glycine, serine, and threonine, while acetate in MVBM was associated with metabolism of taurine and hypotaurine, phosphonate and phosphinate, and glycolysis/gluconeogenesis. The NMR analysis of EPS disclosed shared metabolites including dimethylsulfide, 1-methyluric acid and oxypurinol. This study provides the first extensive investigation into B. pseudomallei biofilm and EPS metabolites, identifying pathways that offer potential targets for combating B. pseudomallei biofilm-associated infections.
期刊介绍:
Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion.
Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context.
Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
