Circadian rhythm in the cyanobacterium Spirulina platensis

Circadian rhythm constitutes key photobiological signals for successive growth of cyanobacteria in variable environment conditions (Cohen and Golden 2015). The endogenous property of diurnal rhythm may alter optimum growth and production of cyanobacterial products in variable environmental

Codon usage bias study in cyanobacteria

Codon is a series of three nucleotides (a triplet) that encodes a specific amino acid residue in a polypeptide chain. There are 61 codons encoding different amino acids and 3 stop codons but only 20 different amino acids

Cyanobacteria: microbial factories for drug discovery

Cyanobacteria, the only prokaryotes that perform the oxygen-producing photosynthesis, are ancient organisms that shaped the atmosphere of our planet. In colonizing most waters and soils, where they face various environmental challenges and competition with many biological organisms,

How are thylakoid membranes shaped and maintained?

An oxygen-rich atmosphere was one of the most important prerequisites for the evolution of complex life on earth. Ancestors of modern-days cyanobacteria floated the earth’s atmosphere with this gas roughly 2.8 billion years ago. To convert carbon

Heavy metals and cyanobacteria: unveiling bioremediation mechanisms

Heavy metals are one of the most common pollutants worldwide, being a serious hazard to the environment and public health. These metals are usually removed from polluted waters by physicochemical methods that can have substantial costs, low

Improved biosafety of genetically modified cyanobacteria

Biosafety is a major concern in biotechnology when genetically modified (GM) organisms are used in a process. With increasing interest for cyanobacterial biotechnology and synthetic biology, it is astonishing that there has been, up to now, no

Finechemical production by photosynthesis

The foreseeable depletion of fossil resources and the increase of atmospheric CO2 leads to a urgent demand of to increase the sustainability of our industry. The pharmaceutical and chemical industries belong to the most waste-intensive and energy

Why identify microscopic photosynthetic bacteria called Cyanobacteria?

Cyanobacteria, the small, harmless bacteria, are invisible to the naked eye. Cyanobacteria photosynthesize like all plants do and thus produce the oxygen we breath. In nature they can be found almost everywhere from the open ocean, to

The environmental toxin BMAA detected in humans – Cause of neurodegenerative diseases?

Alzheimer´s disease, Parkinson´s disease and ALS ( amyotrophic lateral sclerosis ) are the most common neurodegenerative diseases in the world, and cause tremendous human suffering. Only about ten percent of the cases are hereditary, while the rest

Heavy metals and cyanobacteria: towards bioremediation

Heavy metals are one of the most common pollutants worldwide, being a serious hazard to the environment and public health. These metals are usually removed from polluted waters by physicochemical methods that can have substantial costs, low

Using small unmanned aircraft to assess harmful algal blooms in ponds and lakes

Water quality in ponds and lakes is of the utmost importance, it affects drinking water quality, recreational use of lakes, and agricultural production. Excess nutrients entering ponds and lakes, from agricultural, urban and industrial activities, may cause
