Nitrate Uptake in the Halotolerant Cyanobacterium Aphanothece halophytica is energy-dependent driven by ΔpH [PDF]

open access: yesBMB Reports, 2005
The energetics of nitrate uptake by intact cells of the halotolerant cyanobacterium Aphanothece halophytica were investigated. Nitrate uptake was inhibited by various protonophores suggesting the coupling of nitrate uptake to the proton motive force.

Cyanobacterial life at low O 2 : community genomics and function reveal metabolic versatility and extremely low diversity in a Great Lakes sinkhole mat [PDF]

open access: yes, 2012
Cyanobacteria are renowned as the mediators of Earth’s oxygenation. However, little is known about the cyanobacterial communities that flourished under the low‐O 2 conditions that characterized most of their evolutionary history.

Stronger dispersal potential of alkaline phosphatase‐encoding bacteria ensures higher organic phosphorus mineralization rate

open access: yesFunctional Ecology, Volume 39, Issue 3, Page 756-769, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Scientific theory largely neglects linkage between organic phosphorus (Po) mineralization rate and dispersal potential of alkaline phosphatase‐encoding bacteria (PEB) containing the phoD gene. Different densities of substrates (i.e.
