Sustainable agriculture practices involve the application of environment-friendly plant growth promoters and additives that do not negatively impact health ecosystem. Stringent regulatory frameworks restricting use synthetic agrochemicals increase in demand for organically grown crops have paved way development novel bio-based promoters. In this context, microalgae biomass derived offer sources promotors enhance crop productivity impart disease resistance. These beneficial effects could be attributed to presence wide range biomolecules such as soluble amino acid (AA), micronutrients, polysaccharides, phytohormones other signaling molecules biomass. addition, their phototrophic nature, high photosynthetic efficiency, environmental adaptability make them an attractive source biostimulants, biofertilizers biopesticides.

In the coming years, use of microalgal biomass as agricultural biofertilizers has shown promising results. The wastewater culture medium resulted in reduction production costs, making microalgae-based fertilizers highly attractive for farmers. However, occurrence specific pollutants wastewater, like pathogens, heavy metals and contaminants emerging concern (CECs), such pharmaceuticals personal care products may pose a risk on human health. This study presents an holistic assessment grown municipal biofertilizer agriculture. Results showed that pathogens concentrations were below threshold established by European regulation fertilizing products, except cadmium. Regarding CECs, 25 out 29 compounds found wastewater. only three them (hydrocinnamic acid, caffeine, bisphenol A) microalgae used biofertilizer. Agronomic tests performed lettuce growth greenhouse. Four treatments studied, comparing with conventional mineral fertilizer, also combination both them. suggested can help reducing nitrogen dose, since similar fresh shoot weights obtained plants different assessed fertilizers. Lettuce samples revealed presence cadmium CECs all including negative positive controls, which suggests their was not linked to biomass. On whole, this be purposes N need guaranteeing health safety crops.

Abstract Emissions from transportation and industry primarily cause global warming, leading to floods, glacier melt, rising seas. Widespread greenhouse gas emissions resulting warming pose significant risks the environment, economy, society. The need for alternative fuels drives development of third-generation feedstocks: microalgae, seaweed, cyanobacteria. These microalgae offer traits like rapid growth, high lipid content, non-competition with human food, growth on non-arable land using brackish or waste water, making them promising biofuel. unique phototrophic organisms use sunlight, carbon dioxide (CO 2 ) produce biofuels, biochemicals, more. This review delves into realm microalgal exploring contemporary methodologies employed extraction, value-added products, challenges inherent in their commercial-scale production. While cost bioproducts remains high, utilizing wastewater nutrients cultivation could substantially cut production costs. Furthermore, this summarizes significance biocircular economy approaches, which encompass utilization biomass as a feed supplement biofertilizer, biosorption heavy metals dyes. Besides, discussion extends in-depth analysis future prospects commercial potential biofuel within context sustainable development. An economically efficient biorefinery should prioritize affordable nutrient inputs, harvesting techniques, generation valuable by-products. Graphical

Excessive utilization of chemical fertilizers degrades the quality medicinal plants and soil. Bio-organic (BOFs) including microbial inoculants microalgae have garnered considerable attention as potential substitutes for fertilizer to enhance yield. In this study, a field experiment was conducted investigate effects BOF partially substituting on growth plant Polygala tenuifolia.
