Fecha de publicación: 19/06/2008 Fuente: WIPO "organic farming" The present invention has surprisingly discovered that certain spore-forming microorganisms, present in soil, plants and other forms of organic matter, survive excessive heat of a fire within soil or carbonized wood. It has been determined that such microorganisms stimulate plant growth, enhance the nutritional value of plant products, and incorporate carbon dioxide. Accordingly, the present invention provides methods for isolating and identifying plant growth-stimulating microorganisms from soil and from carbonized organic materials. The present invention also provides compositions and methods useful for enhancing plant growth and nutritional properties and for producing DNA-enhanced plants which may be consumed by human individuals for enhancing human DNA. The compositions and methods of the present invention are also useful for improving soil. The invention also provides methods for using charcoal as a carrier to promote plant growth, and to transfer and relocate desirable microorganisms from one ecosystem to another.
