- Claim: 1. A bioinoculant composition comprising cells of at least one purified culture of a Bacillus species selected from the group consisting of i) a Bacillus lentimorbus deposited as NRRL B-30486 exhibiting the following characteristics: a rod shape 1.5 to 2.0 microns in width and 3.0 to 6.0 microns in length, gram positive, negative catalase reaction, positive for anaerobic growth, negative Voges-Proskauer reaction, pH in V-P broth of 5.5, produces acid from D-glucose but not from L-arabinose, D-xylose or D-mannitol, produces gas from glucose, negative for hydrolysis of casein, gelatin and starch, negative for use of citrate, negative for conversion of nitrate to nitrite, negative for indole formation, grows on nutrient broth at pH 5.7 and at pH 6.8, grows in medium containing sodium chloride up to 10%, grows at a temperature of up to 55° C.; ii) a Bacillus subtilis deposited as NRRL B-30487 exhibiting the following characteristics: an oval shape 2.5 microns in width, gram positive, positive catalase reaction, negative for anaerobic growth, positive Voges-Proskauer reaction, pH in V-P broth of 5.8, produces acid from D-glucose, L-arabinose, D-xylose and D-mannitol, does not produce gas from glucose, positive for hydrolysis of casein, gelatin and starch, positive for use of citrate, positive for conversion of nitrate to nitrite, negative for indole formation, grows on nutrient broth at pH 5.7 and at pH 6.8, grows in medium containing sodium chloride up to 5%, grows at a temperature of up to 55° C.; and iii) a Bacillus lentimorbus deposited as NRRL B-30488 exhibiting the following characteristics: a rod shape 1.5 to 2.0 microns in width and 5.0 to 10.0 microns in length, gram positive, negative catalase reaction, positive for anaerobic growth, negative Voges-Proskauer reaction, pH in V-P broth of 5.2, produces acid from D-glucose but not from L-arabinose, D-xylose or D-mannitol, produces gas from glucose, negative for hydrolysis of casein, gelatin and starch, negative for use of citrate, negative for conversion of nitrate to nitrite, negative for indole formation, grows on nutrient broth at pH 5.7 and at pH 6.8, grows in medium containing sodium chloride up to 10%, grows at a temperature of up to 55° C.; and optionally a carrier.
- Claim: 2. The bioinoculant composition of claim 1 , that comprises at least two of the strains i), ii) and iii).
- Claim: 3. The bioinoculant composition of claim 1 , that comprises all three of the strains i), ii) and iii).
- Claim: 4. The bioinoculant composition of claim 3 , in which the three strains are present in approximately equal amounts.
- Claim: 5. The bioinoculant composition of claim 1 , in which the concentration of the cells of each strain is from 10 4 to 10 10 cfu/g of carrier.
- Claim: 6. The bioinoculant composition of claim 1 , in which the concentration of the cells of each strain is from 10 7 to 10 8 cfu/g of carrier.
- Claim: 7. The bioinoculant composition of claim 1 , in which the total concentration of the cells is from 10 4 to 10 10 cfu/g of carrier.
- Claim: 8. The bioinoculant composition of claim 1 , in which the total concentration of the cells is from 10 7 to 10 8 cfu/g of carrier.
- Claim: 9. The bioinoculant composition of claim 1 , in which the generation time of the cells is 55 to 65 minutes when cultured at 30° C.
- Claim: 10. The bioinoculant composition of claim 1 , in which the cells colonize the roots of a plant that contact the composition.
- Claim: 11. The bioinoculant composition of claim 1 , in which the carrier is present and comprises a gum or a sugar.
- Claim: 12. The bioinoculant composition of claim 1 , in which the carrier is present and comprises VERMICULITE, charcoal, carbonation press mud from sugar refining, or a mixture of sulphitation press mud from sugar refining and distillery spent wash.
- Claim: 13. A method for promoting the growth of a plant comprising applying the bioinoculant of claim 1 to a seed of the plant, to soil in which the plant is growing or to the plant directly.
- Claim: 14. The method of claim 13 , in which the bioinoculant is applied to soil to provide 10 6 to 10 8 cfu/g of soil.
- Claim: 15. The method of claim 13 , in which the bioinoculant composition is applied to seed to provide 10 7 to 10 9 cfu/seed.
