Soil microbiome is a dynamic micro-ecosystem driving and fine-tuning several biological processes in the global macro-ecosystems. Its tremendous potential towards mediating sustainability in the ecosystem necessitates the urgent need to store it optimally and efficiently as “next-generation biologicals” for future applications via soil transplantation. The challenge, therefore, is to devise a strategy for the storage of soil microbiome such that its “functionality” is preserved for later application. This review discusses the current endeavours made towards storage of the soil microbiome. The methods for assessing the integrity of soil microbiome by targeting the structural diversity and functional potential of the preserved microbiomes have also been discussed. Further, the success stories related to the storage of fecal microbiome for application in transplants have also been highlighted. This is done primarily with the objective of learning lessons, and parallel application of the knowledge gained, in bringing about improvement in the research domain of soil microbiome storage. Subsequently, the limitations of current techniques of preservation have also been delineated. Further, the open questions in the area have been critically discussed. In conclusion, possible alternatives for storage, comprehensive analyses of the composition of the stored microbiome and their potential have been presented.
