Abstract
The present disclosure is generally directed to an agricultural formulation comprising an anucleated minicells and an anucleated cell-based platforms for encapsulation and scalable delivery of biologically active compounds. Disclosed herein are compositions for the stable and targeted delivery of biologically active compounds within achromosomal and/or anucleated cells onto and/or into a target cell. The present disclosure also provides methods of improving encapsulation and retention of biologically active compounds in achromosomal and/or anucleated cells and delivering biologically active compounds into a target cell.
Claims (37)
1. An agricultural composition, comprising:
a) a minicell encapsulating an insecticidal protein toxin that is capable of controlling or killing a plant pest or a plant pathogen.
2. The agricultural composition of claim 1 , further comprising:
b) an agent for stabilizing said minicell encapsulating the insecticidal protein toxin.
3. The agricultural composition of claim 1 , further comprising:
b) a solid, dry, or liquid carrier.
4. The agricultural composition of claim 1 , wherein the minicell stabilizes the insecticidal protein toxin.
5. The agricultural composition of claim 1 , wherein the insecticidal protein toxin is an orally active insecticidal peptide.
6. The agricultural composition of claim 1 , wherein the insecticidal protein toxin is capable of controlling or killing said plant pest selected from the group consisting of: insect, nematode, aphid, mite, tick, and combinations thereof.
7. The agricultural composition of claim 1 , wherein the insecticidal protein toxin is capable of controlling or killing said plant pathogen selected from the group consisting of: bacteria, fungi, molds, viruses, and combinations thereof.
8. The agricultural composition of claim 1 , wherein the insecticidal protein toxin is capable of controlling or killing at least one member from an order selected from the group consisting of: Coleoptera, Diptera, Hymenoptera, Lepidoptera, Homoptera, Hemiptera, Orthoptera, Thysanoptera, Dermaptera, Siphonaptera, Trichoptera, and combinations thereof.
9. The agricultural composition of claim 1 , wherein the minicell is protease deficient.
10. The agricultural composition of claim 2 , wherein said agent is selected from the group consisting of: glutaraldehyde, formaldehyde, genipin, epigallocatechin gallat, ethylene glycol di(meth)acrylate, methylenebisacrylamide, divinyl benzene and combinations thereof.
11. The agricultural composition of claim 2 , wherein said agent is glutaraldehyde.
12. The agricultural composition of claim 1 , wherein the insecticidal protein toxin is present in an amount from about 0.01% to about 50% of the total mass of the minicell.
13. The agricultural composition of claim 3 , wherein said solid carrier is in a form of granule or pellet and is selected from the group consisting of: diatomaceous earth, loam, silica, alginate, clay, bentonite, vermiculite, and combinations thereof.
14. The agricultural composition of claim 3 , wherein said dry carrier in a form of powder and is selected from the group consisting of: peat, wheat, bran, vermiculite, clay mineral, calcium carbonate, dolomite, gypsum, bentonite, rock phosphate, phosphorous compound, titanium dioxide, humus, talc, alginate, activated charcoal, and combinations thereof.
15. The agricultural composition of claim 3 , wherein said liquid carrier is in a form of liquid or emulsion, and is selected from the group consisting of a surfactant, an emulsifier, a crop oil concentrate, a penetrant, and combinations thereof, wherein said liquid carrier is capable of increasing stability, wettability, or dispersability of said minicell encapsulating the insecticidal protein toxin.
16. The agricultural composition of claim 3 , wherein the agricultural composition is sprayed unto a plant, a plant part, a plant growing medium, or soil.
17. An agricultural composition, comprising:
a) a minicell encapsulating an insecticidal protein toxin that is capable of controlling or killing a plant pest or a plant pathogen; and
b) a first agent for stabilizing said minicell encapsulating the insecticidal protein toxin, wherein said first agent is glutaraldehyde.
18. An agricultural composition of claim 17 , wherein the insecticidal protein toxin is present in an amount from about 0.01% to about 50% of the total mass of the minicell.
19. The agricultural composition of claim 17 , wherein the agricultural composition further comprises a second agent for stabilizing said minicell that is selected from the group consisting of: formaldehyde, genipin, epigallocatechin gallat, ethylene glycol di(meth)acrylate, methylenebisacrylamide, divinyl benzene and combinations thereof.
20. An agricultural composition, comprising:
a) a minicell encapsulating an insecticidal protein toxin that is capable of controlling or killing a plant pest or a plant pathogen; and
b) a solid or dry carrier,
wherein the agricultural composition is applied to a locus that is a plant, a plant part, a plant growing medium, or soil.
21. An agricultural composition of claim 20 , wherein the insecticidal protein toxin is present in an amount from about 0.01% to about 50% of the total mass of the minicell.
22. An agricultural composition of claim 20 , wherein said solid carrier is in a form of granule or pellet and is selected from the group consisting of: diatomaceous earth, loam, silica, alginate, clay, bentonite, vermiculite, and combinations thereof.
23. An agricultural composition of claim 20 , wherein said dry carrier is in a form of powder and is selected from the group consisting of: peat, wheat, bran, vermiculite, clay mineral, calcium carbonate, dolomite, gypsum, bentonite, rock phosphate, phosphorous compound, titanium dioxide, humus, talc, alginate, activated charcoal, and combinations thereof.
24. An agricultural composition, comprising:
a) a minicell encapsulating an insecticidal protein toxin that is capable of controlling or killing a plant pest or a plant pathogen; and
b) a liquid carrier selected from the group consisting of a surfactant, an emulsifier, a crop oil concentrate, a penetrant, and combinations thereof,
wherein said liquid carrier is capable of increasing stability, wettability, or dispersability of said minicell encapsulating the insecticidal protein toxin, and wherein the agricultural composition is applied to a locus that is a plant, a plant part, a plant growing medium, or soil.
25. An agricultural composition of claim 24 , wherein the insecticidal protein toxin is present in an amount from about 0.01% to about 50% of the total mass of the minicell.
26. The agricultural composition of claim 24 , wherein the agricultural composition is sprayable.
