The use of unregulated pesticides and chemical fertilizers can have detrimental effects on biodiversity and human health. This problem is exacerbated by the growing demand for agricultural products. To address these global challenges and promote food and biological security, a new form of agriculture is needed that aligns with the principles of sustainable development and the circular economy. This entails developing the biotechnology market and maximizing the use of renewable and eco-friendly resources, including organic fertilizers and biofertilizers. Phototrophic microorganisms capable of oxygenic photosynthesis and assimilation of molecular nitrogen play a crucial role in soil microbiota, interacting with diverse microflora. This suggests the potential for creating artificial consortia based on them. Microbial consortia offer advantages over individual organisms as they can perform complex functions and adapt to variable conditions, making them a frontier in synthetic biology. Multifunctional consortia overcome the limitations of monocultures and produce biological products with a wide range of enzymatic activities. Biofertilizers based on such consortia present a viable alternative to chemical fertilizers, addressing the issues associated with their usage. The described capabilities of phototrophic and heterotrophic microbial consortia enable effective and environmentally safe restoration and preservation of soil properties, fertility of disturbed lands, and promotion of plant growth. Hence, the utilization of algo-cyano-bacterial consortia biomass can serve as a sustainable and practical substitute for chemical fertilizers, pesticides, and growth promoters. Furthermore, employing these bio-based organisms is a significant stride towards enhancing agricultural productivity, which is an essential requirement to meet the escalating food demands of the growing global population. Utilizing domestic and livestock wastewater, as well as CO flue gases, for cultivating this consortium not only helps reduce agricultural waste but also enables the creation of a novel bioproduct within a closed production cycle.
不规范使用农药和化肥会对生物多样性和人类健康造成有害影响。而这一问题因农产品需求不断增长而加剧。为了解决这些全球性挑战，促进粮食和生物安全，需要一种新形式的农业，使其与可持续发展和循环经济的原则保持一致。这需要发展生物技术市场，最大限度地利用可再生和环保资源，包括有机肥和生物肥料。能够进行产氧光合作用和分子氮同化的光养微生物在土壤微生物群中起着至关重要的作用，与各种微生物相互作用。这表明有可能基于它们来创建人工共生体。微生物共生体具有比单个生物体更多的优势，因为它们可以执行复杂的功能并适应多变的条件，因此成为合成生物学的前沿领域。多功能共生体克服了单培养物的局限性，并产生具有广泛酶活性的生物产品。基于此类共生体的生物肥料是化学肥料的可行替代品，可以解决与使用化学肥料相关的问题。光养和异养微生物共生体的所述能力使得有效且环境安全地恢复和保持土壤特性、受干扰土地的肥力以及促进植物生长成为可能。因此，algocyanobacterial 共生体生物质的利用可以作为化学肥料、农药和生长促进剂的可持续且实用的替代品。此外，利用这些基于生物的生物是提高农业生产力的重要一步，这是满足不断增长的全球人口对粮食需求的必要条件。利用家庭和牲畜废水以及 CO 烟道气来培养这种共生体，不仅有助于减少农业废物，还可以在封闭的生产周期内创造一种新型生物产品。
