Novel membrane proteins and superoxide dismutase activities were identified whose production levels were significantly increased upon alkane degradation in an extremely thermophilic and alkane degrading Geobacillus thermoleovorans B23, previously isolated from a deep subsurface oil reservoir in Japan.
Findings indicate that the F-type ATP synthase is a major generator of proton motive force, even upon aerobic growth, and demonstrate a complementary role for the electron transport chain and Nox in the bioenergetics of E. faecalis.

The discovery and characterization of aen gene cluster is reported, a previously uncharacterized MNIO-associated gene cluster in the opportunistic pathogen Pseudomonas aeruginosa PAO1, and a potential role for aeruginin in chlorite responsive periplasmic stress adaptation is suggested.

Diverse eukaryotes thrive under low oxygen conditions, in part through highly modified mitochondrion-related organelles (MROs) that use alternate metabolic pathways to support ATP production and cofactor recycling. Anaerobic lifestyles have evolved repeatedly across the eukaryotic tree of life, each providing an indepe...

Phosphonates are molecules containing a direct carbon‐phosphorus bond. In nature, these compounds are produced by a variety of organisms, and many environmental microbes are able to degrade specific phosphonates and feed on them. This work focuses on 2‐hydroxyethylphosphonate (HEP)—a natural compound that is found freq...

SUMMARY Acanthamoeba castellanii causes infectious blindness and is a key evolutionary outgroup to humans and fungi. Its divergent mitochondria are of outstanding interest due to predicted aerobic and anaerobic functions with potential for drug targeting. However, a detailed delineation of its bioenergetic machinery, t...

Vibrio natriegens is an emerging model organism in laboratory and biotechnology research that is known for its fast growth rate and diverse metabolic capabilities. However, little is known about its response to oxidative stress. Reactive oxygen species (ROS) are ubiquitous stressors for most aerobic life and without mi...
