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.

The biostimulant segment is becoming increasingly important worldwide. One of the reasons for this that fewer plant protection products are placed on market in European Union, and environmental sustainability also plays an role their use. Biostimulants often used several horticultural sectors, including ornamentals, to strengthen plants, achieve commercial standards, produce quality goods, increase vitality, aid harvesting. This paper presents latest results use biostimulants horticulture, with special emphasis ornamental production. legal regulation regulatory mechanisms described detail review. main groups discussed. response plants abiotic stress, particular physiological, anatomical, genetic changes, regard application detailed.

Cyanobacteria, also called blue-green algae, are a group of prokaryotic microorganisms largely distributed in both terrestrial and aquatic environments. They produce wide range bioactive compounds that mostly used cosmetics, animal feed human food, nutraceutical pharmaceutical industries, the production biofuels. Nowadays, research concerning use cyanobacteria agriculture has pointed out their potential as biofertilizers source compounds, such phycobiliproteins, for plant pathogen control inducers systemic resistance. The alternative products place synthetic ones disease is encouraged by European Directive 2009/128/EC. present up-to-date review gives an overall view recent results on bioprotective effect against fungal oomycete phytopathogens biostimulant properties. We highlight need considering several factors proper sustainable management agricultural crops, ranging from mechanisms which reduce diseases modulate resistance to enhancement growth.

Abstract Agriculture is undergoing a paradigm shift as it moves away from relying only on agrochemicals toward natural-based product to enhance plant growth and productivity while sustainably maintaining soil quality productivity. In this sense, microalgae bacteria offer unique potential due the growing use of novel eco-friendly products such biofertilizers, biostimulants, biopesticides. Microalgae improve crop health by fixing nitrogen, releasing trace elements, solubilizing potassium, phosphorus, producing exopolysaccharides, converting organic matter into utilizable nutrients. They also release bioactive substances including, carbohydrates, proteins, enzymes, vitamins, hormones, promote growth, control pests, mitigate stress responses. Even though has long been known that produce various signaling molecules (like phytohormones, polysaccharides, lipids, carotenoids, phycobilins, amino acids) which are effective in production, targeted applications these science still very early stages development. beneficial because they oxygen extracellular chemicals, bacteria, turn, provide with carbon dioxide, other nutrients exchange. This review discusses possible role increasing yield, protecting crops, fertility stability, points out interactions may have better enhancement production sustainable way than using either them alone.

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.
