Green Synthesis and Characterization of Silver Nanoparticles with High Antibacterial Activity Using Cell Extracts of Cyanobacterium Pseudanabaena/Limnothrix sp.

open access: yesNanomaterials, 2022
In this work, we demonstrated the ability of the cyanobacterium Pseudanabaena/Limnothrix sp. to produce ultra-small silver nanoparticlesin the forms of metallic silver (Ag0) and silver oxides (AgxOy) via a facile green synthetic process.

Biomass and β-Glucosidase Production by the Cyanobacterium Pseudanabaena sp. under Heterotrophic Conditions

open access: yesBiomass, 2022
A cyanobacterium producing β-glucosidase was isolated from Lake Pamvotis located in Ioannina in Greece. This microorganism, named Pamv7, was identified as Pseudanabaena sp. using phylogenetic characterization. The high-throughput BiologMicroPlate™ method,

Population structure of an Antarctic aquatic cyanobacterium

open access: yesMicrobiome, 2022
AbstractBackgroundAce Lake is a marine-derived, stratified lake in the Vestfold Hills of East Antarctica with an upper oxic and lower anoxic zone. Cyanobacteria are known to reside throughout the water column. ASynechococcus-like species becomes the most abundant member in the upper sunlit waters during summer while persisting annually even in the ...

Outdoor Inclined Plastic Column Photobioreactor: Growth, and Biochemicals Response of Arthrospira platensis Culture on Daily Solar Irradiance in a Tropical Place

open access: yesMetabolites, 2022
Implementation of outdoor photobioreactors has been challenged by an extremely oversaturated daily peak of solar irradiance. This study aims to understand the role of column size and paranet shading as well as to investigate the most convenient light ...

Production of thermostable phycocyanin in a mesophilic cyanobacterium

open access: yesMetabolic Engineering Communications, 2021
Phycocyanin (PC) is a soluble phycobiliprotein found within the light-harvesting phycobilisome complex of cyanobacteria and red algae, and is considered a high-value product due to its brilliant blue colour and fluorescent properties. However, commercially available PC has a relatively low temperature stability.

Cannabinomimetic Lipid from a Marine Cyanobacterium. [PDF]

open access: yesJournal of Natural Products, 2011
NMR-guided fractionation of two independent collections of the marine cyanobacteria Lyngbya majuscula obtained from Papua New Guinea and Oscillatoria sp. collected in Panama led to the isolation of the new lipids serinolamide A (3) and propenediester (4). Their structures were determined by NMR and MS data analysis.

Influence of salinity on the growth and biochemical composition of the cyanobacterium Synechococcus sp.

open access: yesCiencias Marinas, 2005
The study of cyanobacteria isolated from hypersaline environments is of interest because of their metabolic and ecophysiologic versatility in adapting to extreme conditions of salinity, temperature, irradiance and nutrient availability.
