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,

Small secreted proteins enable biofilm development in the cyanobacterium Synechococcus elongatus. [PDF]

open access: yes, 2016
Small proteins characterized by a double-glycine (GG) secretion motif, typical of secreted bacterial antibiotics, are encoded by the genomes of diverse cyanobacteria, but their functions have not been investigated to date.

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.

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium [PDF]

open access: yes, 2017
Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into heterocysts, devoted to nitrogen ...
