Aluminium Uptake by Anabaena cylindrica [PDF]
Summary: Atomic absorption spectrophotometry was used to characterize aluminium uptake by the cyanobacterium Anabaena cylindrica. An EDTA-washing procedure was used to distinguish between adsorbed and intracellular aluminium. The intracellular aluminium content increased with increasing external concentration and time.

Cyanobacterial Mn-catalase ‘KatB’: Molecular link between salinity and oxidative stress resistance
Catalases are ubiquitous enzymes that detoxify H2O2 in virtually all organisms exposed to oxygen. The filamentous, nitrogen-fixing cyanobacterium, Anabaena PCC 7120, shows the presence of 2 genes (katA and katB) that encode Mn-catalases. We have recently

ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

ABSTRACT The current study assessed the impact of organic and inorganic feeding management on water quality, growth performance and plankton communities in a pond‐based polyculture system over 9 months, using three treatments: Ctrl (C), organic feeding (T1) and inorganic feeding (T2). Significant differences were observed in electrical conductivity (EC)

Ultrasound contrast agents, including microbubbles and nanobubbles, transform imaging and targeted therapy through precise engineering of size, shell composition, and surface properties. This review explores how these innovations enable tissue‐specific delivery, enhance therapeutic efficacy, and extend applications from vascular imaging to tumor ...

Evolution of molecular communication in the permanent Azolla symbiosis
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Crystal structure of thioredoxin-2 from Anabaena [PDF]
Thioredoxins are ubiquitous proteins that serve as reducing agents and general protein disulfide reductases. The structures of thioredoxins from a number of species, including man and Escherichia coli, are known. Cyanobacteria, such as Anabaena, contain two thioredoxins that exhibit very different activities with target enzymes and share little ...

Abstract Climate change increases the magnitude and frequency of extreme weather events. This includes severe summer storms altering lake physical structure, biodiversity and ecosystem processes. However, insights into lake responses to extreme storms and the underlying mechanisms primarily rest on unreplicated and observational case studies, without ...
