Kinetic study of the redox processes in carbon electrodes with Geobacter sulfur...
Peixoto, L.; Santos, Andréa F. S.; Machado, Idalina; Sousa, A. M. M.; Brito, A. G.; Parpot, Pier; Pereira, M. O.; Nogueira, R.Geobacter sulfurreducens is a bacteria that can transfer electrons directly to the electrode from different external membrane cytochromes. Each cytochrome is associated with a range of electrical potentials, being energetically more favourable than some others. Different growth conditions of the bacteria, such as temperature, may influence the prevalence of certain cytochromes in the external membrane. The aim ...
Impact of nutritional conditions on colony morphology variants isolated from P....
Sousa, A. M. M.; Machado, Idalina; Pereira, M. O.In natural habitats, microorganisms are challenged all the time due to stress conditions imposed by the surrounding environment. To adapt to these environmental changes, bacteria alter their physiological and genetic traits. This adaptive behavior may be achieved by phenotype switching. This process consists in a reversible switch of phenotypes, as a mechanism ON/OFF, which occurs at high frequencies than spont...
