Title:	Phosphate solubilizing rhizobacteria bacillus firmus as biofertilizer to increase canola yield
Abstract:	A biologically pure phosphate solubilizing plant growth promoting rhizobacteria (PGPR) XSB375 was isolated from canola rhizosphere and identified as Bacillus firmus is provided herein. The PGPR is capable to solubilize phosphate that enhance plant available phosphorous. The PGPR XSB375 enhances seed germination, early emergence, plant vigor, root and shoot growth, and higher crop yield. This increased crop growth, development and yield is attributed from not only the greater phosphate solubilization making more available phosphorus to plant but also making other essential plant nutrients more available to the plant and the like. The application of this phosphate solubilizing PGPR can be done as liquid suspension or solid materials using onto soil, potting mix, seeds, seed pieces, seedlings, foliage, carrier materials, roots and planting soil.

Application Number:	15/496,804
Patent Claims:	1. A method for promoting or increasing or improving plant growth and/or plant yield comprising: preparing a composition comprising a high density aliquot of plant growth promoting (PGPR) XSB375 Bacillus firmus strain deposited as ATCC#PTA-120309; applying said composition to a soil environment in which seeds or seedlings have been or will be planted; growing said seeds or seedlings into plants in said soil environment, said PGPR XSB375 colonizing said soil environment and secreting phosphatase activity in an amount sufficient to increase solubilisation of phosphate in the soil environment to HPO.sub.4.sup.2- and H.sub.2PO.sub.4.sup.- for uptake by the plants such that growth of said plants is increased or improved; and harvesting said plants. 2. The method according to claim 1 wherein the high density aliquot comprises at least about 1.times.10.sup.7 colony forming units per ml of PGPR XSB375. 3. The method according to claim 1 wherein the biologically pure culture is grown to a high density in a fermentor in growth media that increases or enhances the plant growth promoting properties of PGPR XSB375. 4. The method according to claim 3 wherein the growth media is a tryptone-yeast extract nutrient broth. 5. The method according to claim 4 wherein the tryptone-yeast extract has a pH of between 6.7-7.9. 6. The method according to claim 1 wherein the aliquot is prepared by growing a biologically pure culture of PGPR XSB375 Bacillus firmus strain deposited as ATCC#PTA-120309 is grown in a fermentor containing a tryptone-yeast extract nutrient broth with a pH between 6.7-7.9 to a density of at least about 1.times.10.sup.7 colony forming units per ml in early stationary phase and aliquoting the culture. 7. The method according to claim 6 wherein the culture is aliquoted as liquid aliquots wherein each liquid aliquot has a density of at least about 1.times.10.sup.8 colony forming units per ml. 8. The method according to claim 6 wherein the culture is aliquoted by pelleting the culture to produce a cell mass, drying the cell mass, freeze drying the dried cell mass to a powder and aliquoting the powder, wherein the powder has a density of at least about 1.times.10.sup.7 colony forming units per gram. 9. The method according to claim 1 wherein the soil environment or potting mixture includes phosphorus as a fertilizer. 10. The method according to claim 1 wherein the PGPR XSB375 promotes uptake of macronutrients or micronutrients in the plant. 11. The method according to claim 1 wherein the plant has a nutrient phosphorus requirement or the plant would benefit from increased phosphate uptake. 12. The method according to claim 1 wherein the plant is canola. 13. The method according to claim 1 wherein the plant is an oil seed, legume, non-legume, cereal, root plant, vegetable, grass, forage, turf, fruits and flowering plant. 14. The method according to claim 1 wherein the plant is selected from the group consisting of canola, soybean, sunflower, flax, hemp, wheat, barley, corn, millet, oat, pea, lentil, beans, peanut, alfalfa, clover, sugar beets, potatoes, carrots, cabbages, tomatoes, radishes, capsicum, cucumber, grasses, turf, cantaloupe, melon, fruits and flowers. 15. The method according to claim 14 wherein the flowers are selected from the group consisting of rose, chrysanthemum, lily and gerbera. 16. The method according to claim 1 further including applying to said soil environment a herbicide or fungicide or insecticide or seed treatment chemical. 17. The method according to claim 1 wherein the PGPR XSB375 is applied as consortia with another microorganism. 18. The method according to claim 1 wherein the PGPR XSB375 is applied in combination with other plant growth promoting rhizobacteria.
