Abstract
Some aspects of the present disclosure relate to methods and devices for identifying soil bacteria-enriching agents that selectively enrich a desired species of bacteria in a soil microbiome. In some embodiments, the soil bacteria-enriching agent comprises a carbon substrate and/or a chemoeffector. Some aspects of the present disclosure relate to methods of enriching a desired species of bacteria in a soil microbiome using one or more soil bacteria-enriching agents.
Claims20
A method of engineering a soil microbiome, the method comprising:
- a) selecting one or more carbon substrates that are able to enrich a desired bacterial species in a soil microbiome as compared to enrichment of one or more different bacteria in the soil microbiome;
- b) selecting one or more chemoattractants that are able to attract the desired bacterial species to the soil microbiome as compared to attraction of one or more different bacteria to the soil microbiome;
- and
- c) applying the one or more selected carbon substrates and chemoattractants to soil comprising a soil microbiome comprising the desired bacteria, wherein
- application of the one or more of the selected carbon substrates and/or chemoattractants to the soil comprising a soil microbiome enriches the concentration of the desired bacteria in the soil microbiome as compared to the concentration of the one or more desired bacteria prior to applying the one or more selected carbon substrates and/or chemoattractants to the soil.
A method of selecting a chemoattractant that is able to enrich the growth of a desired bacterial species in a soil microbiome, the method comprising:
- measuring the attraction of the desired bacterial species and at least one different bacterial species to one or more candidate chemoattractants, and
- selecting a chemoattractant that is able to more strongly attract the desired bacterial species as compared to the at least one different species of bacteria.
