Extracellular polysaccharides (EPSs) produced by microalgae and cyanobacteria are
molecules with a great ecological significance for the producing organisms, serving in a …

Exopolysaccharides (EPSs) from microorganisms are essential harmless natural
biopolymers used in applications including medications, nutraceuticals and functional foods …

Harmful algal blooms (HABs) are symptomatic of ecosystem imbalance, often caused by the
many environmental changes that demonstrate the expanding global human footprint and …

Quantifying the spatial and temporal dynamics of stream metabolism across stream
networks is key to understanding carbon cycling and stream food web ecology. To better …

Benthic diatoms live in photoautotrophic/heterotrophic biofilm communities embedded in a
matrix of secreted extracellular polymeric substances. Closely associated bacteria influence …

Diatoms are considered unicellular eukaryotic organisms exclusively depositing biogenic
silica. Heretofore there has been no report of calcification by these algae. Here it is shown …

The need for new technologies more efficient and less expensive to remove heavy metals
from aqueous environments has lead to the development of novel biosorption-based …

The diatom Didymosphenia geminata has emerged as a major global concern, as both an
aggressive invader of rivers and streams in the southern hemisphere, and for its ability to …

For the first time, the three-dimensional (3D) internal structure of naturally produced
Didymosphenia geminata frustules were nondestructively visualized at sub-100 nm …

This study addresses for the first time the chemistry and biological activity of polysaccharides
isolated from Didymosphenia geminata. Fourier-transform infrared spectroscopy (FTIR) and …
