Diversity of the Cyanobacteria
2017The cyanobacteria are an ancient lineage of photo-oxygenic bacteria. Globally responsible for much of the primary productivity and nitrogen fixation, they are also evolutionarily significant as the photosynthetic members of serial endosymbiotic events leading to the establishment of chloroplasts.

Cyanobacteria as an eco‐friendly resource for biofuel production: A critical review
Biotechnology progress (Print), 2019Cyanobacteria are photosynthetic microorganisms which can be found in various environmental habitats. These photosynthetic bacteria are considered as promising feedstock for the production of the third‐ and the fourth‐generation biofuels.

Transformation of Cyanobacteria
2008Cyanobacteria are a diverse and successful group of bacteria defined by their ability to carry out oxygenic photosynthesis. They occupy diverse ecological niches and are important primary producers in the oceans. Cyanobacteria are amenable to genetic manipulation. Some strains are naturally transformable. Many others have been transformed in the lab by

Chemotaxonomy of cyanobacteria
Phytochemistry, 1995Abstract The fatty acid-based classification system divides cyanobacteria into four groups. These groups include strains that contain C 18 fatty acids with three, four or no double bonds. The fatty acid composition of several cyanobacterial strains that we have analysed suggests the existence of a fifth group that consists of C 18 polyunsaturated ...

Carotenoids in cyanobacteria have two main functions: they serve as light-harvesting pigments in photosynthesis, and they protect against photooxidative damage. Carotenoids are generally hydrophobic isoprenoid compounds that are synthesized in membranes.

Cyanobacteria were recovered from each of 38 soil samples collected from local rice fields. Of the 84 species belonging to 31 genera that were isolated, 42 were heterocystous diazotrophic species belonging to 14 genera and the remaining were non-heterocystous. Fischerella, Nostoc and Calothrix were widespread.

Hydrogenase activities in cyanobacteria
Biochimie, 1986In the unicellular Anacystis nidulans, the expression of both the H2-uptake (with phenazine methosulfate or methylene blue as the electron acceptor) and H2-evolution (with methyl viologen reduced by Na2S2O4) was dependent on Ni in the culture medium.

Biotechnological uses of cyanobacteria
Biotechnology Advances, 1985Cyanobacteria (blue-green algae) are O(2)-evolving photosynthesizing prokaryotes that have an extensive history of use as a human food source and as a fertilizer in rice fields. They have also been recognized as an excellent source of vitamins and proteins and as such are found in health food stores in North America and elsewhere.

Energy biotechnology with cyanobacteria
Current Opinion in Biotechnology, 2009The world's future energy demand calls for a sustainable alternative for the use of fossil fuels, to restrict further global warming. Harvesting solar energy via photosynthesis is one of Nature's remarkable achievements. Existing technologies exploit this process for energy 'production' via processing of, for example, part of plant biomass into ethanol,
