“…However, in heterocystous cyanobacteria, the processes of photosynthesis and nitrogen fixation occur simultaneously and independently of the time of day, while in non-heterocystous cyanobacteria, these processes occur separately: nitrogen fixation, at night; photosynthesis during the day [ 8 ]. In the cyanobacterial species that form heterocysts, the nitrogenase is located in the heterocyst and is, thus, protected from the inhibitory effects of oxygen [ 9 , 10 , 11 , 12 , 13 ]. They are more attractive in terms of productivity and can enrich the soil with 20–30 kg N ha −1 per year, which is a great economic advantage for agriculture.…”

The potential of cyanobacteria to perform a variety of distinct roles vital for the biosphere, including nutrient cycling and environmental detoxification, drives interest in studying their biodiversity. Increasing soil erosion and the overuse of chemical fertilizers are global problems in developed countries. The option might be to switch to organic farming, which entails largely the use of biofertilisers. Cyanobacteria are prokaryotic, photosynthetic organisms with considerable potential, within agrobiotechnology, to produce biofertilisers. They contribute significantly to plant drought resistance and nitrogen enrichment in the soil. This study sought, isolated, and investigated nitrogen-fixing cyanobacterial strains in rice fields, and evaluated the effect of Mo and Fe on photosynthetic and nitrogenase activities under nitrogen starvation. Cyanobacterial isolates, isolated from rice paddies in Kazakhstan, were identified as Trichormus variabilis K-31 (MZ079356), Cylindrospermum badium J-8 (MZ079357), Nostoc sp. J-14 (MZ079360), Oscillatoria brevis SH-12 (MZ090011), and Tolypothrix tenuis J-1 (MZ079361). The study of the influence of various concentrations of Mo and Fe on photosynthetic and nitrogenase activities under conditions of nitrogen starvation revealed the optimal concentrations of metals that have a stimulating effect on the studied parameters.

Content of Lipids, Fatty Acids, Carbohydrates, and Proteins in Continental Cyanobacteria: A Systematic Analysis and Database Application

et al. 2023

The lipid, fatty acid, protein, and carbohydrate contents in cyanobacterial strains and biomass can vary by orders of magnitude. Many publications (thousands of peer-reviewed articles) require more work to extract their precise concentration values (i.e., different units, inaccurate data), which makes them not easily exploitable. For this purpose, tables have been compiled from the literature data, including lipids, fatty acids, proteins, and carbohydrates composition and quantities in cyanobacteria. A lot of data (323) were collected after careful a literature search, according to selected criteria in order to distinguish separately cyanobacteria, and according to categories of genus and species and generate average values of the contents of these cell components. These data are exploited in a first systematic analysis of the content in types of strains. Our database can be a powerful tool for biologists, chemists, and environmental agencies to determine the potential concentration of high-value chemical building blocks directly from low-value bloom biomass, cell cultures, or debris in the sediment, offering the potential to minimize environmental waste and add value to the agro-industrial residues. The database can also support strategies for food manufacturers to develop new products with optimized properties for veterinarian applications.

“…The first medium (M) contained only mineral substrate components, and the second (MO) was prepared on the basis of mineral and organic substances. As a mineral nutrient medium M, the standard composition of the Tamiya medium [7][8] is used. Mineral-organic environment MO was prepared from dry cattle manure without bedding.…”

The article studies the experimental process of cultivation of microalgae in a photobioreactor (PBR) to study the effect of technological conditions on the productivity of microalgae. This process allows obtaining initial data for the development of closed cycles of using the energy potential of alga mass in heat and power supply of various industries, including agricultural enterprises (livestock complexes, poultry farms, etc.) The scheme of a closed cycle of power supply of the cattle complex allows obtaining hot water, feed additives to the cattle ration, bio humus, motor biofuel and carbon dioxide, which is advisable to use in the process of cultivating microalgae. The experiments were carried out on a photobioreactor for cultivating microalgae with an intelligent control system. The developed photobioreactor differs from the known ones in the pulsating hydrodynamic regime of feeding the nutrient solution, which provides an increase in the productivity of the microalgae cultivation up to 15%. The experimental model of the cultivation conditions of the microalga Ch. Vulgaris on a combined diet (Tamiya medium + manure substrate) showed a noticeable increase in crop productivity when adding cattle manure extract to the nutrient medium in an amount from 30 to 60% (vol.). This can be used in the development of closed cycles of heat and power supply for cattle farms based on biofuels of the third generation, obtained from the phytomass of microalgae.
