Described herein is the isolation and identification of a number of sulfur oxidizing plant growth promoting rhizobacteria: RAY12, identified as Achromobacter piechaudii; RAY28, identified as Agrobacterium tumefaciens, RAY132, identified as Stenotrophomonas maltophilia; and RAY209, identified as Delftia acidovorans. The PGPR act to oxidize elemental sulfur which in turn provides sulfate for the plants. As a result of this arrangement, plants are able to grow more efficiently and effectively and have enhanced growth characteristics, for example, but by no means limited to, increased vigor, early emergence, increased emergence rate, increased biomass, increased plant leaf area, higher crop yield, increased pod number, increased pod weight, increased root biomass, increased seed weight, increased macro- and micro- nutrient uptake and the like. The sulfur-oxidizing PGPR may be applied to seeds, seed pieces, carrier materials, roots and planting soil.
L'invention concerne l'isolation et l'identification d'un certain nombre de rhizobactéries sulfo-oxydantes qui favorisent la croissance des plantes, à savoir, les RAY12, appelées Achromobacter piechaudii; les RAY28, appelées Agrobacterium tumefaciens, les RAY132, appelées Stenotrophomonas maltophilia; et enfin, les RAY209, appelées Delftia acidovorans. Les PGPR agissent de façon à oxyder le soufre élémentaire qui fournit à son tour le soufre aux plantes. Les plantes peuvent ainsi croître efficacement et présenter des caractéristiques de croissance améliorées, notamment et non exclusivement, une vigueur renforcée, une émergence précoce, une vitesse d'émergence décuplée, une biomasse plus importante, une surface foliaire plus étendue, un meilleur rendement de culture, un plus grand nombre de cabosses, un poids de cabosse plus élevé, une biomasse racinaire plus développée, un poids de graines plus élevé, ainsi qu'une meilleure absorption des macro et micronutriments et analogue. On peut ainsi appliquer les PGPR sulfo-oxydantes aux graines, fragments de plants, matières portantes, racines et sol de plantation.
