Occurrence of C35–C45 polyprenols in filamentous and unicellular cyanobacteria [PDF]
Organic Geochemistry, 2010 Polyprenols, regular (head-to-tail) isoprenoid alcohols with 7-9 prenyl units, were tentatively identified in several cultivated cyanobacteria Heptaprenol (C35), octaprenol (C40) and a suite of nonaprenols (C45) were present in unicellular and filamentous non-heterocystous cyanobacteria, while they were absent in heterocystous species Structurally ...

Restoration Ecology, EarlyView.Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

EcoMat, Volume 8, Issue 9, September 2026.A 3D‐printed polypyrrole/reduced graphene oxide (PPy/rGO) lattice anode with high porosity enhances biophotovoltaic (BPV) power density and current density by coordinating biofilm adhesion, light penetration, and endogenous mediator diffusion. Optimized PPy electropolymerization maximizes photocurrent and cell–electrode affinity.

Determination of Intracellular Osmolytes in Cyanobacterial Cells
Bio-Protocol, 2018 Most of the cyanobacteria accumulate osmolytes including sucrose, glucosylglycerol, in their cells in response to salt stress. Here we describe a protocol of our laboratory for extraction and quantification of cyanobacterial intracellular sucrose and ...

Cellular differentiation and the NtcA transcription factor in filamentous cyanobacteria [PDF]
FEMS Microbiology Reviews, 2004 Some filamentous cyanobacteria can undergo a variety of cellular differentiation processes that permit their better adaptation to certain environmental conditions. These processes include the differentiation of hormogonia, short filaments aimed at the dispersal of the organism in the environment, of akinetes, cells resistant to various stress ...

Global Change Biology Communications, Volume 1, Issue 3, September 2026.Under ocean acidification, turf algae are favored over corals, shifting the competition outcome and decreasing coral survival. The local pH microenvironment under the turf, resulting from associated biological activity, drives the dissolution of the coral carbonate skeleton.

Biofuel production utilizing a dual-phase cultivation system with filamentous cyanobacteria.
Journal of Biotechnology, 2018 Biomass yields and biofuel production were examined in a dual (solid and liquid)-phase cultivation system (DuPHA) with the unique filamentous cyanobacteria, Pseudanabaena sp. ABRG 5-3 and Limnothrix sp. SK1-2-1. Continuous circular cultivation was driven

Giant phytoplankton revealed by in situ imaging
Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate
