Microalgae as Biofertilizers: A Sustainable Way to Improve Soil Fertility and Plant Growth

Sustainability, Journal Year: 2023, Volume and Issue: 15(16), P. 12413 - 12413

Published: Aug. 15, 2023

The intensification of agricultural production in response to the global population increase and growing demand for food has raised significant concerns regarding environmental impacts over past few decades. Currently, modern agriculture aims improve quantity quality crop yield, minimizing negative effects treatments on environment. Recently, microalgae have found extensive application as a valuable biological resource across multiple industries, including sector, biofuel production, pharmaceutical industry. In agriculture, been seen promising sustainable alternative agrochemicals, offering range benefits soil fertility, optimize nutrient management, reduce reliance synthetic fertilizers. general, demonstrated efficient cycling abilities, assimilating converting essential nutrients, such nitrogen, phosphorus, potassium, into forms readily available plants. Additionally, they produce bioactive substances, phytohormones, which direct impact physiological processes plants promote their growth. Microalgae can also establish beneficial interactions with other microorganisms, supporting growth bacteria fungi, thus promoting healthy microbiome. On hand, photosynthetic harness sunlight convert carbon dioxide (CO2) organic matter through photosynthesis. This ability allows them sequester contribute by reducing greenhouse gas emissions. present work provides an overview potential biofertilizers, highlighting unique characteristics, benefits, main limitations effective implementation agriculturally practices.

Microalgal and Nitrogen-Fixing Bacterial Consortia: From Interaction to Biotechnological Potential

Plants, Journal Year: 2023, Volume and Issue: 12(13), P. 2476 - 2476

Published: June 28, 2023

Microalgae are used in various biotechnological processes, such as biofuel production due to their high biomass yields, agriculture biofertilizers, of high-value-added products, decontamination wastewater, or biological models for carbon sequestration. The number these applications is increasing, and such, any advances that contribute reducing costs increasing economic profitability can have a significant impact. Nitrogen fixing organisms, often called diazotroph, also great potential, mainly an alternative chemical fertilizers. Microbial consortia typically perform more complex tasks than monocultures execute functions challenging even impossible individual strains species. Interestingly, microalgae diazotrophic organisms capable embrace different types symbiotic associations. Certain corals lichens exhibit this relationship nature, which enhances fitness. However, be artificially created laboratory conditions with the objective enhancing some processes each organism carries out independently. As result, utilization garnering interest potential yields biomass, well producing derived products serving purposes. This review makes effort examine associations aim highlighting improving processes.

Microalgae and cyanobacteria polysaccharides: Important link for nutrient recycling and revalorization of agro-industrial wastewater

Applied Food Research, Journal Year: 2023, Volume and Issue: 3(1), P. 100296 - 100296

Published: April 10, 2023

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.
