Biochar as a microbial carrier
The invention relates to a microbial delivery system where biochar acts as a carrier for microbes.
1. A microbial delivery system comprising:
biochar having pores; and
microbes retained on the surface or in the pores of the biochar, where the microbes are inoculated into the pores of the biochar using a surfactant.
2. The delivery system of claim 1 , where at least some of the microbes are inoculated into the pores of the biochar.
3. The delivery system of claim 2 , where the microbes are inoculated into the pores of the biochar using mechanical, chemical, or biological assistance to move the microbes either into the pores of the biochar or onto the surfaces of the biochar.
4. The delivery system of claim 3 where the microbes are inoculated into the pores of the biochar using the application of positive or negative pressure.
5. The delivery system of claim 1 where the microbes are retained by the biochar through mixing the biochar and microbes together.
6. The delivery system of claim 5 where the microbes are retained on the biochar by suspending the microbes in liquid and depositing the microbes on the biochar.
7. The delivery system of claim 1 where the microbes retained by the biochar are selected from the group consisting of: Bacillus, Pseudomonas, Rhizobium, Burkholderia, Achromobacter, Agrobacterium, Microccocus, Aereobacter, Flavobacterium, Erwinia, Klebsiella , and Enterobacter , including Bacillus mucilaginosus, Bacillus edaphicus, Bacillus circulans, Paenibacillus spp., Acidothiobacillus ferrooxidans, Pseudomonas cepacia, Burkholderia cepacia, Klebsiella variicola, Pantoea agglomerans ; and fungi Glomus mosseae, Glomus intraradices, Aspergillus terreus and Aspergillus niger.
8. The delivery system of claim 1 where the biochar is treated biochar.
9. The delivery system of claim 8 where the biochar has been treated to alter one or more of the following properties of the biochar: pH; hydrophobicity: hydrophilicity; ability of the biochar to hold moisture; ability of the biochar to retain and exchange certain types of nutrients; ion exchange capacity; physical protection from environmental hazards or protozoa; presence or absence of nutrients, micronutrients, or sources of metabolic carbon; or ability of the biochar to host other symbiotic microbes or plant systems.
10. The delivery system of claim 1 , where at least some of the microbes are retained on the biochar through integrated growth with the biochar.
11. Biochar having pores where pores are filled with a media containing microbes, where the media is infused into the pores of the biochar using a surfactant.
12. The biochar of claim 11 where the microbes includes microorganisms selected from the group consisting of: Bacillus, Pseudomonas, Rhizobium, Burkholderia, Achromobacter, Agrobacterium, Microccocus, Aereobacter, Flavobacterium, Erwinia, Klebsiella , and Enterobacter , including Bacillus mucilaginosus, Bacillus edaphicus, Bacillus circulars, Paenibacillus spp., Acidothiobacillus ferrooxidans, Pseudomonas cepacia, Burkholderia cepacia, Klebsiella varlicola, Pantoea agglomerans ; and fungi Glomus mosseae, Glomus intraradices, Aspergillus terreus and Aspergillus niger.
13. The biochar of claim 11 where the media is further infused into the pores of the biochar using positive or negative pressure.
14. The biochar of claim 11 where the surfactant treatment comprises adding 1% surfactant to the media.
15. The biochar of claim 11 where the pores of the biochar are treated prior to infusion with the media.
16. The biochar of claim 11 where the moisture content of the pores of the biochar is adjusted prior to infusion with the media.
17. A method for creating enhanced biochar, the method comprising the steps of infusing media containing microbes into the pores of biochar using a surfactant.
18. The method of claim 17 where the media is further infused into the pores of the biochar using positive or negative pressure.
19. The method of claim 17 where the media includes microorganisms selected from the group consisting of: Bacillus, Pseudomonas, Rhizobium, Burkholderia, Achromobacter, Agrobacterium, Microccocus, Aereobacter, Flavobacterium, Erwinia, Klebsiella , and Enterobacter , including Bacillus mucilaginosus, Bacillus edaphicus, Bacillus circulars, Paenibacillus spp., Acidothiobacillus ferrooxidans, Pseudomonas cepacia, Burkholderia cepacia, Klebsiella variicola, Pantoea agglomerans ; and fungi Glomus mosseae, Glomus intraradices, Aspergillus terreus and Aspergillus niger.
