Due to the constant growth of human population and anthropological activity, it has become necessary use sustainable affordable technologies that satisfy current future demand for agricultural products. Since nutrients available plants in soil are limited need increase yields crops is desirable, chemical (inorganic or NPK) fertilizers been widespread over last decades, causing a nutrient shortage due their misuse exploitation, because uncontrolled these products, there latent environmental health problem globally. For this reason, green biotechnology based on microalgae biomass proposed as alternative development improvers crop cultivation phytoremediation. This review explores long-term risks using both (cancer hypoxia) environment (eutrophication erosion), well potential substitute fertilizer different treatments application methods implementation soil; additionally, can be source carbon mitigation wastewater treatment agro-industrial processes.

Utilizing the power of plant growth promoting rhizobacteria on reducing mineral fertilizer, improved yield, and nutritional quality of Batavia lettuce in a floating culture

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Янв. 18, 2024

In soilless cultivation, plants are grown with nutrient solutions prepared mineral nutrients. Beneficial microorganisms very important in plant nutrition. However, they not present culture systems. this study we investigated the impact of introducing Plant Growth Promoting Rhizobacteria (PGPR) as an alternative to traditional fertilizer hydroponic floating lettuce cultivation. By reducing fertilizers at various ratios (20%, 40%, 60%, and 80%), replacing them PGPR, observed remarkable improvements multiple growth parameters. Applying PGPR led significant enhancements weight, leaf number, area, dry matter, chlorophyll content, yield, uptake soilles lettuce. Combining 80% demonstrated a yield that did significantly differ from control treatment 100% fertilizers. Moreover, application improved essential concentrations enhanced human nutritional quality, including higher levels phenols, flavonoids, vitamin C, total soluble solids. has potential sustainable substitute for synthetic leading environmentally friendly nutritionally enriched farming.

Nitrogen (N) is the most limiting nutrient for production of vegetable crops, but anthropogenic sources pose risks due to its transformation into several reactive forms and movement throughout environment. The bulk N research date improve Use Efficiency (NUE) has followed a reductionist factorial approach focused on synthetic application rates crop growth response, under monocultures. increased adoption diversified cropping systems, organic sources, alternative management practices makes it more challenging unravel form transformation, movement, uptake dynamics, in time space. Here, based selected review recent literature, we propose holistic highlight key variables as well multilevel system, genetic, environmental, ecological, socioeconomic interactions cycle NUE. best strategies NUE include both inorganic rate calibration studies, germplasm selection, rotations, identification x interactions, pest water management.

Microalgal cultures for the remediation of wastewaters with different nitrogen to phosphorus ratios: Process modelling using artificial neural networks

Environmental Research, Год журнала: 2023, Номер 231, С. 116076 - 116076

Опубликована: Май 6, 2023

Microalgae have remarkable potential for wastewater bioremediation since they can efficiently uptake nitrogen and phosphorus in a sustainable environmentally friendly treatment system. However, composition greatly depends on its source has significant seasonal variability. This study aimed to evaluate the impact of different N:P molar ratios growth Chlorella vulgaris nutrient removal from synthetic wastewater. Furthermore, artificial neural network (ANN) threshold models, optimised by genetic algorithms (GAs), were used model biomass productivity (BP) nitrogen/phosphorus rates (RRN/RRP). The various inputs culture variables these parameters was evaluated. Microalgal not limited average productivities specific similar between experiments. Nutrient efficiencies/rates reached 92.0 ± 0.6%/6.15 0.01 mgN L−1 d−1 98.2 0.2%/0.92 0.03 mgP phosphorus. Low concentration low (e.g., 2 3, yielding 36 mgDW mgP−1 39 3 mgP−1, respectively), while with high 66 67, 9.0 0.4 mgN−1 8.8 0.3 mgN−1, respectively). ANN models showed fitting performance, coefficients determination 0.951, 0.800, 0.793 BP, RRN, RRP, respectively. In summary, this demonstrated that microalgae could successfully grow adapt but impacted variations, especially lowest highest ratios. GA-ANN be relevant tools microalgal modelling control. Their performance characterising biological system contribute reducing experimental effort monitoring (human resources consumables), thus decreasing costs production.

The Science of The Total Environment, Год журнала: 2023, Номер 904, С. 166878 - 166878

Опубликована: Сен. 9, 2023

Microalgae can produce biostimulants in form of phytohormones, which are compounds that, even if applied low concentrations, have stimulant effects on plants growth and enhance their quality resistance to stress. Considering that microalgal biomass grow recovering nutrients from wastewater, this circular approach allows use residues for the production high added value (such as phytohormones) at cost. The interest microalgae recently raised. Scientists focused direct application these cellular extracts plants, while number studies identification bioactive molecules, such is very scarce. Two cyanobacteria strains (Synechocystis sp. (SY) Phormidium (PH)) a chlorophyte (Scenedesmus (SC)) were cultured laboratory-scale PBRs with working volume 2.5 L secondary urban wastewater varying N:P ratio cultures obtain highest productivity. variation affects growth, SY PH presented higher productivities (73 48 mg L-1 d, respectively) under (> 22:1). Microalgal was freeze-dried phytohormones content measured ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). three showed similar profiles, being auxin (indole-3-acetic acid, IAA) most abundant (72 ng g-1DW SY). Proteins major macronutrient all strains, reaching %DW culture. To optimize production, balance between compounds, productivity removal should be taken into consideration. In sense, SC promising strain, showing N P rates % 59 %, producing phytohormones.
