The use of algae to create phytosanitary products

Abstract

Microalgae and macroalgae have beneficial properties for nutrition, biocontrol, immunity and health, etc., especially in the context of integrated multitrophic aquaculture. Projects to improve the bioavailability, digestibility and pretreatment of algae, as well as those aimed at controlling crops with a high protein content (macro/micro), are growing in popularity. Bioremediation will be available for fertilization as part of a mineral and nitrogen recycling approach improved by the effects of these matrices on soil structuring and nutrient absorption. The advantage of microalgae is that they have a fairly short reproduction cycle (about half a day), which allows efficient production of biomass in large quantities. Microalgae have a wide variety of original molecules in their cells. This biomass is rich in lipids, proteins, vitamins and antioxidants. Microalgae form the basis of the concept, they have caused one of the greatest climatic changes in the history of the Earth. Their metabolism, based on photosynthesis, added huge amounts of oxygen to the "toxic primitive atmosphere of the Earth." The main characteristics of microalgae. Most microalgae are called photoautotrophic or autotrophic. Microalgae are very diverse and about 30,000 species have already been analyzed. This number is less than 10% of the estimated existing total. The most common classes in terms of relative abundance are diatoms (bacillariophyceae), green algae (chlorophyceae), cyanobacteria or blue-green algae (cyanophyceae) and golden algae (chrysophyceae). Most of the research is devoted to finding the best strains. The choice of microalgae species ultimately depends on the available organisms capable of synthesizing target products and achieving yields necessary to meet economic and technical constraints. Therefore, when choosing, it is necessary to take into account the prevailing climatic conditions, especially average and minimum temperatures and the availability of necessary nutrients. The use of algae to create phytosanitary products is a promising and in-demand area of research.
