Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

FEBS Open Bio, Volume 15, Issue 7, Page 1028-1040, July 2025.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Time-series analyses of Monterey Bay coastal microbial picoplankton using a ‘genome proxy’ microarray [PDF]

, 2010
To investigate the temporal, spatial and phylogenetic resolution of marine microbial community structure and variability, we designed and expanded a genome proxy array (an oligonucleotide microarray targeting marine microbial genome fragments and genomes)

Time course transcriptomic profiling suggests Crp/Fnr transcriptional regulation of nosZ gene in a N2O-reducing thermophile

iScience
Summary: Nitrosophilus labii HRV44T is a thermophilic chemolithoautotroph possessing clade II type nitrous oxide (N2O) reductase (NosZ) that has an outstanding activity in reducing N2O to dinitrogen gas. Here, we attempt to understand molecular responses

Engineered Living Energy Materials

Interdisciplinary Materials, Volume 4, Issue 3, Page 412-455, May 2025.
Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their

90‐day oral toxicity study in rats of a protein‐rich powder derived from Xanthobacter sp. SoF1

Journal of Applied Toxicology, Volume 44, Issue 11, Page 1816-1830, November 2024.
Abstract Xanthobacter sp. SoF1 (SoF1) is an autotrophic hydrogen‐oxidizing bacteria that produces protein‐rich biomass and has potential to be an alternative protein source that is more environmentally sustainable than animal and plant derived proteins.

A new family of periplasmic-binding proteins that sense arsenic oxyanions [PDF]

, 2018
Arsenic contamination of drinking water affects more than 140 million people worldwide. While toxic to humans, inorganic forms of arsenic (arsenite and arsenate), can be used as energy sources for microbial respiration. AioX and its orthologues (ArxX and

Succession of Bacteria and Archaea Within the Soil Micro‐Food Web Shifts Soil Respiration Dynamics

Environmental Microbiology, Volume 26, Issue 11, November 2024.
Nematode grazing and plant litter are important biotic control mechanisms of the soil microbiome. We show that major bacterial and archaeal taxa respond in five distinct ways to top‐down and bottom‐up controls, resulting in a succession of soil microbiota and shifts in soil respiration dynamics. ABSTRACT Bacterivorous nematodes are important grazers in

Community analysis of betaproteobacterial ammonia-oxidizing bacteria using the amoCAB operon [PDF]

, 2009
The genes and intergenic regions of the amoCAB operon were analyzed to establish their potential as molecular markers for analyzing ammonia-oxidizing betaproteobacterial (beta-AOB) communities.
