Abstract This study exploited the different combinations of nutritional modes (autotrophic, mixotrophic and heterotrophic) green alga Scenedesmus obliquus in a two-stage cultivation process to remediate wastes as well maximise production high-protein algal biomass. The was first cultivated autotrophically Stage-one, using 0.5% digestate nutrient source natural light support growth; afterward, culture concentrated used Stage-two under modes. 2.5% anaerobic from food waste provide inorganic nutrients; sugar recovered confectionery manufacturer organic carbon mixo- hetero-trophic growth. In algae removed ammonium phosphate at 9.1 mg L −1 day 3.8 , respectively, yield approached carrying capacity 1 g dry weight per liter. Stage-two, population increased faster heterotrophic modes, reaching final concentration 7.2–10.5 than autotrophic mode. Ammonium were consumed about twice rate mode, 90–100% within 48–72 h. biomass had protein content 44% compared only 32% demonstrated that coupling growth S. can be both boost protein-rich biomass, which beneficial sustainable circular bioeconomy.

Despite the high amount of wastewater generated by agroindustry around world, only a limited number alternatives for its reuse or revalorization have been applied. One most suitable agro-industrial is production extracellular polysaccharides (EPS) from microalgae and cyanobacteria. Due to complex carbohydrate metabolic pathway in cyanobacteria, EPS produced can be employed residual water treatment, emulsification, gelling, as prebiotic ingredient, among others. biological activities, including antioxidant, anti-inflammatory, antitumor, antimicrobial related their molecular weight, sulfate, uronic acid, charged group content. In this review, cyanobacteria production, functional properties, sustainable are addressed. Microalgal polysaccharide wastewaters has potential become standard transforming linear food processing systems into circular economy alternatives.

Plants experience constant exposed to diverse abiotic stresses throughout their growth and development stages. Given the burgeoning world population, pose significant challenges food nutritional security. These are complex influenced by both genetic networks environmental factors, often resulting in crop losses, which can reach as high fifty percent. To mitigate effects of on crops, various strategies rooted improvement genomics being explored. In particular, utilization biostimulants, including bio-based compounds derived from plants beneficial microbes, has garnered considerable attention. Biostimulants offer potential reduce reliance artificial chemical agents while enhancing efficiency promoting plant under stress condition. Commonly used friendly ecology human health, encompass inorganic substances (e.g., zinc oxide silicon) natural seaweed extracts, humic substances, chitosan, exudates, microbes). Notably, prioritizing environmentally biostimulants is crucial prevent issues such soil degradation, air water pollution. recent years, several studies have explored biological role production, focusing particularly mechanisms effectiveness horticulture. this context, we conducted a comprehensive review existing scientific literature analyze current status future research directions concerning use plant-based oxide, silicon, selenium aminobutyric acid, acids, chitosan for tolerance plants. Furthermore, correlated molecular modifications induced these with different physiological pathways assessed impact performance response stresses, provide valuable insights.

Volatile organic compounds (VOCs) are low molecular weight molecules that tend to evaporate easily at room temperature because of their boiling points. VOCs emitted by all organisms; therefore, inter- and intra-kingdom interactions have been established, which fundamental the structuring life on our planet. One most studied through is between microorganism (mVOCs) plants, including those agricultural interest. The mVOC generate various advantages for ranging from promoting growth activation defense pathways triggered salicylic acid (systemic acquired resistance) jasmonic (induced systemic protect them against phytopathogens. Additionally, mVOCs directly inhibit phytopathogens, thereby providing indirect protection plants. Among current problems extensive use chemicals, such as fertilizers, intended combat production loss, pesticides phytopathogen infection. This causes in food safety environmental pollution.
