Journal ArticleDOI
Contribution of extracellular polymeric substances from Shewanella sp. HRCR-1 biofilms to U(VI) immobilization
Bin Cao,Bulbul Ahmed,David W. Kennedy,Zheming Wang,Liang Shi,Matthew J. Marshall,James K. Fredrickson,Nancy G. Isern,Paul D. Majors,Haluk Beyenal +9 more
TL;DR: The goal of this study was to quantify the contribution of extracellular polymeric substances (EPS) to U(VI) immobilization by Shewanella sp.
Journal ArticleDOI
Characterization of Mono- and Mixed-Culture Campylobacter jejuni Biofilms
Tuba Ica,Vildan Caner,Ozlem Istanbullu,Hung Duc Nguyen,Bulbul Ahmed,Douglas R. Call,Haluk Beyenal +6 more
TL;DR: The results indicate that biofilms provide an environmental refuge that is conducive to the survival of C. jejuni, one of the most common causes of human gastroenteritis.
Journal ArticleDOI
In situ effective diffusion coefficient profiles in live biofilms using pulsed-field gradient nuclear magnetic resonance
Ryan S. Renslow,Paul D. Majors,Jeffrey S. McLean,James K. Fredrickson,Bulbul Ahmed,Haluk Beyenal +5 more
TL;DR: The results demonstrate that advanced biofilm models should use a variable effective diffusivity which changes with time and location in the biofilm.
Journal ArticleDOI
Biofilm shows spatially stratified metabolic responses to contaminant exposure
Bin Cao,Paul D. Majors,Bulbul Ahmed,Ryan S. Renslow,Crystal P. Silvia,Crystal P. Silvia,Liang Shi,Staffan Kjelleberg,James K. Fredrickson,Haluk Beyenal +9 more
TL;DR: MRI and spatial mapping of the diffusion revealed localized changes in the water diffusion coefficients in the biofilms, suggesting significant contaminant-induced changes in structural or hydrodynamic properties during bioremediation.
Journal ArticleDOI
A voltammetric flavin microelectrode for use in biofilms
TL;DR: The development of a flavin microelectrode capable of measuring flavins inside a living biofilm and applying it to a biofilm which produces flavins shows the possibility that flavins are produced in the anaerobic zone to act as intermediate electron acceptors in the deeper parts of the biofilm, where there is no oxygen.
