Reducing Potential

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.

Work Done

The aim of the study was to investigate as to whether piezoelectric energy harvesting could be a viable contributor to a source of renewable energy for the future. Here, a keyboard usage study was conducted using a data gathering computer program called WhatPulse in which participants and their keyboards were monitored for one week. The results were used in conjunction with power output figures from work done by Wacharasindhu and Kwon (2008) who prototyped a piezoelectric keyboard and found it was capable of producing 650 µJ of energy per keystroke. The results from this study suggest piezoelectric keyboards could not be used to create self-sustaining systems for any of the devices proposed. Further uses for the stored energy have been suggested but the question to the viability of piezoelectric keyboards as a useful energy source looks discouraging. Other applications for the technology could be explored to enhance power output and utilise larger amounts of vibrational energy.
