Towards sustainable agriculture through synthetic microbial communities: beyond multifunctional roles, integrated applications, and ecological considerations

Agriculture faces significant challenges, including climate change, resource limitations, and land degradation, threatening food security. Traditional practices reliant on chemical inputs are often unsustainable, emphasizing the need for alternative solutions. Synthetic microbial communities (SynComs) are artificially assembled microbial consortia designed to improve plant health, reduce chemical inputs, and enhance soil fertility, responding to the limitations of monoculture systems and synthetic agrochemicals. SynCom holds the transformative potential to drive sustainable agriculture. These consortia can serve as biofertilizers, improving nutrient cycling and stress tolerance. They are also involved in bioremediation, transforming pollutants into non-toxic products, and converting crop residues into valuable bio-based products. Integrating SynComs into agricultural practices has the potential to address environmental challenges, promote sustainable farming, and provide long-term food security and ecosystem health. However, realizing their full capacity requires interdisciplinary research, supportive policy and incentive structures, and engagement with farmers through participatory research and knowledge transfer.
