Soil bacteria, often unseen yet integral to the ecosystem, form an invisible army crucial for climate resilience and mitigation. These microscopic organisms play multifaceted roles, from sequestering carbon and nitrogen fixation to enhancing soil structure and nutrient availability. Their pivotal function extends to mitigating climate change impacts by aiding in carbon storage and reducing greenhouse gas emissions through various metabolic processes. Moreover, certain soil bacteria exhibit resilience to changing environmental conditions. Exploring sustainable agricultural practices and biotechnological interventions offers a promising approach to enhancing climate resilience and mitigating ecological challenges. Research on soil microbes’ role in countering climate change effects and understanding their response in diverse ecosystems is crucial for enabling plants to withstand evolving stressors and minimizing adverse impacts. Soil microbes that make them significant in agriculture must be investigated, especially in light of the effects of changing climatic scenarios on crop production and the need to eliminate numerous problems related to the use of pesticides in this sector. Reviewing patents in a particular field is of paramount importance, thus, a thorough description of a patent that was published in the field of microorganisms’ role in climate resilience and mitigation was added to the concluding section of this chapter.
