SOLID INOCULUM CARRIED IN A SUPERABSORBENT AGRO-PELLET WITH A VARIABLE VOLUME, OPERATING IN A NATURAL MINIFERMENTER, AND PRODUCTION METHOD

摘要

The invention relates to a solid inoculum carried in a superabsorbent agro-pellet with a variable volume, operating in a natural mini fermenter preloaded with an anhydrous nutritive medium, encouraging rapid regrowth of the viable micro-organisms and the continuous multiplication thereof. The liquid inoculum incorporated into the carrier at a low density of microbial cells is preferably comprised between 1/500e and 1/10e of the density recommended by the norm for a liquid inoculum of the same strain. The bioaugmentation of the microbial population is between 104 and 106 additional microbial cells. The solid inoculum according to the invention allows the preservation of the microorganisms and the handling thereof in advantageous conditions. It is not exposed to soil leaching caused by water. Said inoculum is used for the biological treatment of crops for the development and/or the preservation thereof from parasite attacks.

主权项

1. Solid inoculum carrier made of a superabsorbent biodegradable plastic composite matrix agro-pellet capable of absorbing water or an aqueous solution up to 500% of its own weight, said agro-pellet being pre-loaded with a nutritive medium, wherein said agro-pellet performs simultaneously the functions of support and fermenter, enabling the multiplication within the agro-pellet of the microorganisms comprising said inoculum, said nutritive medium being anhydrous in said agro-pellet and with a concentrated from 2 to 10 times greater than that of an adapted liquid culture medium according to the standard for the strain to inoculate, and wherein the density of the inoculum being between 1/500th and 1/10th of the quantity recommended for a liquid inoculum of the same strain.
