Photophobotaxis of single‐celled and filamentous cyanobacteria
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

Kineochelins—A New Group of Siderophores From an Antarctic Bacterium
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Bakteriopolis: Introducing Microbes to Society
Bakteriopolis is a travelling exhibition that brings the invisible microbial world into public spaces. The project is accompanied by a broad communication strategy to engage diverse audiences. ABSTRACT Microorganisms, while being fundamental to life on Earth, are often associated with negative perceptions and global crises.

Heterocyst differentiation in the cyanobacterium Mastigocladus laminosus [PDF]
The morphological and ultrastructural aspects of heterocyst differentiation in the branching, filamentous cyanobacterium Mastigocladus laminosus were examined with light and electron microscopy. The earliest differentiation stages involved cytoplasmic changes, including (i) rapid degradation of carboxysomes, (ii) degradation of polysaccharide granules,

The cyanobacterium Anabaena sp. PCC 7120 forms filaments of communicating cells. Under conditions of nitrogen scarcity, some cells differentiate into heterocysts, allowing the oxygen-sensitive N2-reduction system to be expressed and operated in oxic ...

Abstract In cyanobacteria, the redox‐sensitive protein OpcA acts as a metabolic switch for G6PDH, enabling rapid adjustment of reducing power generation from glycogen catabolism and thereby precisely regulating carbon flux between anabolic and catabolic pathways.

Modeling heterocyst pattern formation in cyanobacteria [PDF]
To allow the survival of the population in the absence of nitrogen, some cyanobacteria strains have developed the capability of differentiating into nitrogen fixing cells, forming a characteristic pattern. In this paper, the process by which cyanobacteria differentiates from vegetative cells into heterocysts in the absence of nitrogen and the elements ...
