Functional Characterization of the FNT Family Nitrite Transporter of Marine Picocyanobacteria

Life, 2015
Many of the cyanobacterial species found in marine and saline environments have a gene encoding a putative nitrite transporter of the formate/nitrite transporter (FNT) family.

Nonsterile Cultivation of the Thermophilic Cyanobacterium Parathermosynechococcus lividus PCC 6715 in a Floating Light Ball Reactor (FLBR) on 53‐L Scale for Zeaxanthin Production

ChemFoodChem, Volume 2, Issue 3, September 2026.
We demonstrate cultivation of the thermophilic cyanobacterium Parathermosynechococcus lividus PCC 6715 at 40–55°C and 4 × 53 L scale using a Floating Light Ball Reactor (FLBR). The system enabled continuous illumination, non‐sterile operation with low contamination, flexible handling, and zeaxanthin production of 1.4–2.0 mg g−1, supporting future ...

Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

A dual role of phycoerythrin in the nitrogen‐fixing cyanobacterium Crocosphaera watsonii: From light‐harvesting to nitrogen reservoir

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Unicellular diazotrophic cyanobacteria contribute up to ~50% of marine N2 fixation, and Crocosphaera watsonii, characterized by high phycoerythrin (PE) content, is among one of the key species in tropical and subtropical oceans. Although recent observations have revealed heterogeneous N2 fixation activity within C.

Behavior and Mechanism of Cesium Biosorption from Aqueous Solution by Living Synechococcus PCC7002

Microorganisms, 2020
Many efforts have focused on the adsorption of metals from contaminated water by microbes. Synechococcus PCC7002, a major marine cyanobacteria, is widely applied to remove metals from the ocean’s photic zone.

Does nutrient scarcity select for Synechococcus clade III in the Mediterranean Sea?

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Synechococcus inhabit both nutrient‐rich estuaries and oligotrophic waters, yet exhibit distinct niche segregation across phylogenetic clades. Previous studies indicated clade III predominated in the ultraoligotrophic Mediterranean Sea. However, the mechanisms underlying clade III's dominance over other clades in ultraoligotrophic waters ...

Evolutionary insights into bilin biosynthesis: Functional characterization of pre‐PcyA enzymes

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Biosynthesis of the linear tetrapyrrole phycocyanobilin (PCB) by the ferredoxin‐dependent bilin reductase (FDBR) PcyA is essential for light‐harvesting and regulatory processes in diverse photosynthetic organisms, yet its evolutionary origins are not fully understood. PcyA evolved from pre‐PcyA proteins found in diverse bacteria.

Molecular logics in dual sensor regulation of diguanylate cyclase activity—Phosphorylation OR blue‐light activation

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Bacterial cells use multiple environmental cues to regulate levels of the second messenger cyclic dimeric GMP. This compound influences key lifestyle decisions such as motility, biofilm formation, or virulence. Although many diguanylate cyclases (DGCs) combined with various sensory domains have been studied previously, how distinct inputs are ...
