Patterned Hydrophobic Domains in the Exopolymer Matrix of Shewanella oneidensis MR-1 Biofilms

Hydrogen metabolism in Shewanella oneidensis MR-1.

Shewanella oneidensis MR-1 is a facultative sediment microorganism which uses diverse compounds, such as oxygen and fumarate, as well as insoluble Fe(III) and Mn(IV) as electron acceptors. The electron donor spectrum is more limited and includes metabolic end products of primary fermenting bacteria, such as lactate, formate, and hydrogen. While the utilization of hydrogen as an electron donor h...

Spatiometabolic stratification of Shewanella oneidensis biofilms.

Biofilms, or surface-attached microbial communities, are both ubiquitous and resilient in the environment. Although much is known about how biofilms form, develop, and detach, very little is understood about how these events are related to metabolism and its dynamics. It is commonly thought that large subpopulations of cells within biofilms are not actively producing proteins or generating ener...

Initial Phases of biofilm formation in Shewanella oneidensis MR-1.

Shewanella oneidensis MR-1 is a facultative Fe(III)- and Mn(IV)-reducing microorganism and serves as a model for studying microbially induced dissolution of Fe or Mn oxide minerals as well as biogeochemical cycles. In soil and sediment environments, S. oneidensis biofilms form on mineral surfaces and are critical for mediating the metabolic interaction between this microbe and insoluble metal o...

The Shewanella oneidensis MR - 1 fluxome under various oxygen conditions

The Shewanella oneidensis MR-1 fluxome under various oxygen conditions Abstract 1 The central metabolic fluxes of Shewanella oneidensis MR-1 were examined under 2 carbon-limited (aerobic) and oxygen-limited (micro-aerobic) chemostat conditions using 13 C 3 labeled lactate as the sole carbon source. The carbon labeling patterns of key amino acids in 4 biomass were probed using both GC-MS and 13 ...
