Cyanobacteria has a highly diversity group that consists of photosynthetic prokaryotic microorganisms. Cyanobacteria that produce lots of metabolites such as amino acids, proteins, vitamins etc. have a wide spread. In this study, the effects of different concentrations of Spirulina platensis extracts on the germination of wheat and barley seeds and root-stem length, lateral root number and fresh-dry weight were investigated. The application of S5 (100% cell extract) showed an inhibitory effect on seed germination on both wheat and barley. S2 (25% cell extract) and S4 (75% cell extract) applications had a positive effect on germination and seedling development in wheat. In barley, S2 (25% cell extract) application activated germination and seedling growth and other concentration applications did not create a positive effect. As a result; cyanobacterial extract has positive effects on seed germination and plant growth-development and it is possible to produce a commercial and ecological biostimulant by developing different extract concentrations.

“…Other examples that may illustrate plant hormone action in a simple, classroom‐based context, are algal extracts that contain growth stimulants and that can easily be used in plant growth experiments . Algal extracts have been shown to contain cytokinins, and indeed, one can observe more bushy growth of a treated plant, which is in accordance with the functions of cytokinins in promoting shoot growth.…”

Systems thinking is an increasingly recognized paradigm in education in both natural and social sciences, a particular focus being, naturally, in biology. This article argues that plant biology, and in particular, plant hormonal signaling, provides highly illustrative models for learning and teaching in a systems paradigm, because it offers examples of highly complex networks, ranging from the molecular-to ecosystem-scale, and in addition lends itself to the use of real-life biological objects.

“…Probably due to population rise and technological advancement, fertilizers are heavily utilized in modern agriculture to increase output, however, the heavy use of inorganic and chemical fertilizers could form a threat to human health and the environment (Win et al, 2018). Due to the aforementioned, efforts are being channelled into the exploitation of microorganisms as a more eco-friendly approach for conservational agriculture.…”

HighlightsTrends in the uses of Spirulina over different decades were critically examinedFindings from surveyed literature indicated that Spirulina utilization was mainly focused on its food and feed potential before the last 20-30 yearsThe review observed that research focused on the health and pharmaceutical uses, biofertilizer, bioplastic, cosmetic, bioenergy and pollution control applications of Spirulina are trends that sprouted out within the last 20-25 years.The review has successfully compiled numerous uses of Spirulina microalga for easy readership by readers since many studies have been performed on the uses Spirulina but reviews of this type spanning through different beneficial aspects of Spirulina are still scarce. Hence, this review fills such gap. AbstractThere is a need to have a single document that summarises the present day uses of Spirulina. In this review, the research trend on the health and other applications of Spirulina microalga was critically evaluated. In terms of the health uses, antioxidant, antibacterial, and immunostimulant effects of Spirulina were emphasized. Other uses of the microalga discussed include the use of Spirulina for human and animal food, bioenergy, pollution and ecotoxicology control, cosmetics, bioplastics and biofertilizers. Literature search revealed that Spirulina polysaccharides, phycocyanin size and content play a role in antioxidant activity and DNA repair. The double bonds and positions of –COOH and –OH in Spirulina phenol content and γ-linolenic fatty acids (γ-LFA) have antimicrobial activity. Some compounds in Spirulina improve immune, increase survival rate and enhance distribution of proteins like hepcidin and TNF-α in animal models. High protein, vitamins, fatty acids (FAs) and glycoproteins in Spirulina are easily digestible due to its lack of cellulose and can improve human and livestock growth. Spirulina produces biodegradable and non-toxic biodiesel and useful co-products. Absorption of heavy metals by chemisorption occurs in Spirulina. Phycocyanin and β-carotene of Spirulina increase skin health, Spirulina also cause high cell proliferation and aids wound healing. Bioplastics produced from Spirulina are biodegradable, non-toxic with high blends. Biofertilizers from Spirulina have little or no residual risks, adds soil Nitrogen through Spirulina Nitrogen fixation ability. In addition, the survey of published works on Spirulina for the past two decades indicates that more research is been carried out in recent years using Spirulina, especially studies involving its health potentials and those concerned with molecular analysis. In conclusion, Spirulina is an exceptional commodity with numerous applications, and probably, some of its compounds causing those effects are yet to be isolated and that is one area for further research.
