Competition and interdependence define interactions of Nostoc sp. and Agrobacterium sp. under inorganic carbon limitation [PDF]

npj Biofilms and Microbiomes
Cyanobacteria of the Nostoc genus are capable of forming symbiotic relationships with plants but also serve as a hub for heterotrophic bacteria. By comparing the axenic strain Nostoc punctiforme PCC 73102 and the xenic strains Nostoc sp.

Preliminary Characterization of a Spray-Dried Hydrocolloid from a High Andean Algae (Nostoc sphaericum)

Foods, 2022
The search for new natural sources of hydrocolloids with stabilizing, thickening, and good binding capacity, from raw materials that are environmentally friendly and that contribute to the circular economy is a challenge for the food industry. The aim of

Genome Evolution of Filamentous Cyanobacterium Nostoc Species: From Facultative Symbiosis to Free Living

Microorganisms, 2021
In contrast to obligate bacteria, facultative symbiotic bacteria are mainly characterized by genome enlargement. However, the underlying relationship of this feature with adaptations to various habitats remains unclear.

Comparison of the hydrocolloids Nostoc commune and Nostoc sphaericum: Drying, spectroscopy, rheology and application in nectar

Scientia Agropecuaria, 2020
Present work proposes the substitution of traditional food stabilizers from the hydrocolloids of algae. Hydrocolloids from Nostoc commune and Nostoc sphaericum were extracted, characterized by infrared spectroscopy, and modelled their rheological ...

Anabaenopeptins from Nostoc edaphicum CCNP1411

International Journal of Environmental Research and Public Health, 2022
Cyanobacteria of the Nostoc genus belong to the most prolific sources of bioactive metabolites. In our previous study on Nostoc edaphicum strain CCNP1411, the occurrence of cyanopeptolins and nostocyclopeptides was documented. In the current work, the production of anabaenopeptins (APs) by the strain was studied using genetic and chemical methods ...
