The marine chemolithotrophic ammonium-oxidizing bacterium Nitrosomonas crytolerans was monitored during recovery after 5 weeks of energy-source deprivation. The organism responded immediately to the addition of [Formula: see text], producing [Formula: see text] at a constant rate. The cells used stored energy sources (ATP) and reducing equivalents (possibly NAD(P)H + H+) to immediately begin biosynthesis. However, these sources were quickly exhausted. Consequently, anabolism (14CO2 incorporation) decreased until levels of ATP and reducing potential were increased through oxidation of [Formula: see text]. Electron transport system activity steadily increased after the addition of [Formula: see text]. The increases in activities were greater than the increase in the total number of cells, suggesting that the increase in activity of the whole culture was due to either a physiological change in each cell or a reactivation of cells which had entered dormancy during energy-source deprivation. These results indicate that N. cryotolerans is well adapted to oligotrophic environments.

Short And Long Term

For renewable energies to succeed in replacing fossil fuels, large-scale and affordable solutions are needed for short and long-term energy storage. A potentially inexpensive approach of storing large amounts of energy is through the use of a concentration flow cell that is based on cheap and abundant materials. Here, we propose to use aqueous iron chloride as a reacting solvent on carbon electrodes. We suggest to use it in a red-ox concentration flow cell with two compartments separated by a hydrocarbon-based membrane. In both compartments the red-ox couple of iron II and III reacts, oxidation at the anode and reduction at the cathode. When charging, a concentration difference between the two species grows. When discharging, this concentration difference between iron II and iron III is used to drive the reaction. In this respect it is a concentration driven flow cell redox battery using iron chloride in both solutions. Here, we investigate material combinations, power, and concentration relations.
