BIOSTIMULANT BASED ON BACTERIA FOR BETTER ADAPTATION OF PLANTS TO HYDRIC AND OSMOTIC STRESSES
Streptomyces acrimyciniStreptomyces mutabilisPolyangiumbrachysporumbrachysporum). This invention also describes a new bacterial inoculum formulation based on the optimisation of certain biological properties in these bacteria (N1, N4 and N3), namely their properties in increasing the water retention capacity of soils and in solubilising and mobilising the forms of potassium for the plant from complex inorganic forms which are not accessible to the plant without the microbial partner thereof (BCD and BSK). By including together propagules of these bacteria and perlite as a matrix, the ability of the (BDC and BSK) to increase the sponge capacity of soils and to solubilise the insoluble forms of potassium and make them accessible to the plant will be increased. As a result, the role of the (BDC and BSK- Plant) partnership on the development of the host plant will be optimised by intimately combining the impact of these bacteria on the plant directly (control of absorption, conduction and transpiration) and indirectly (availability of the water in soils in a uniform manner, by modification of the components that cause water loss by leaching, evaporation).

The invention relates to a method for the industrial preparation of phosphoric acid from an aqueous suspension comprising water and particles of at least one phosphate material dispersed in the presence of at least one additive of the anionic polymer type. Phosphoric acid is obtained by treating this suspension with at least one strong acid. The polymer is obtained by polymerization reaction of at least one acid selected from acrylic acid, methacrylic acid and salts thereof.
The invention relates to the use of this anionic polymer as well as the method for improving the rheology of the suspension and the hydrodynamics of the reaction medium in which the reactions for the manufacture of phosphoric acid take place.

Abstract
A method for manufacturing a ceramic material for thermal energy storage, includes producing a mixture of at least particles of clay and particles of natural and/or synthetic phosphate, and water, the mixture comprising between 0.5% and 40% by weight of phosphate compared to the weight of the mixture with the exception of water, and shaping and firing of the mixture to obtain the ceramic material. A ceramic material for thermal energy storage includes: a matrix of clay and, if appropriate, sand, and particles of a natural and/or synthetic phosphate dispersed in the matrix, the ceramic material comprising between 0.5% and 40% by weight of phosphate compared to the weight of the ceramic material.
