Envisioning role of ammonia oxidizing bacteria in bioenergy production and its challenges: a review.

Ammonia oxidizing bacteria (AOB) play a key role in the biological oxidation of ammonia to nitrite and mark their significance in the biogeochemical nitrogen cycle. There has been significant development in harnessing the ammonia oxidizing potential of AOB in the past few decades. However, very little is known about the potential applications of AOB in the bioenergy sector.

Investigation on anneal-tuned properties of ZnFeO nanoparticles for use in humidity sensors.

The effect of different annealing temperatures on structural, optical and magnetic properties of ZnFeO nanoparticles prepared using the coprecipitation technique has been investigated. With the increase in annealing temperature, crystallinity and average crystallite size of nanoparticles increased. The average crystallite size was found to be 5.

Arsenite biotransformation by Rhodococcus sp.: Characterization, optimization using response surface methodology and mechanistic studies.

A large population of the world is under increased health risk due to consumption of arsenic contaminated groundwater. The present study investigates the arsenic resistance and arsenic biotransforming ability in three bacterial species, namely Bacillus arsenicus, Rhodococcus sp. and Alcaligenes faecalis for employing them in potential groundwater bioremediation programmes.
