Exploring the Potential and Challenges of Fermentation in Creating Foods: A Spotlight on Microalgae

Fermentation
Fermentation is an ancient bioprocess that harnesses the power of microorganisms to convert raw ingredients into valuable and safe food products. There has been a growing interest in using fermentation to create safe, nutritious, and sustainable foods ...

Lipopolysaccharides of the cyanobacterium Microcystis aeruginosa [PDF]

European Journal of Biochemistry, 1983
Lipopolysaccharides (LPS) of two isolates of Microcystis aeruginosa were extracted with phenol/water and purified. Cesium chloride gradient ultracentrifugation of these preparations yielded only one fraction. The LPS contained significant amounts of 3‐deoxy‐d‐manno‐octulosonic acid, glucose, 3‐deoxy sugars, glucosamine, fatty acids, fatty acid esters ...

Microbial Hydrolysates as Amino Acid Source in Cell Culture Media for Cellular Agriculture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The high cost of cultivation media remains one of the barriers to the commercialization of cultivated meat. Current serum‐free media reduce reliance on fetal bovine serum but only achieve modest cost savings. Especially at larger scales (> 20 m3), pharmaceutical‐grade amino acids and recombinant proteins remain major cost drivers.

Diel infection of cyanobacteria by cyanophages

Frontiers in Marine Science, 2016
Cyanobacteria exhibit biological rhythms as an adaptation to the daily light-dark (diel) cycle. Light is also crucial for bacteriophages (cyanophages) that infect cyanobacteria.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Sodium-coupled motility in a swimming cyanobacterium [PDF]

Journal of Bacteriology, 1987
The energetics of motility in Synechococcus strain WH8113 were studied to understand the unique nonflagellar swimming of this cyanobacterium. There was a specific sodium requirement for motility such that cells were immotile below 10 mM external sodium and cell speed increased with increasing sodium levels above 10 mM to a maximum of about 15 microns/s

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.
