Title (EN) MICROBIAL BIOCEMENTATION
(FR) BIOCEMENTATION MICROBIENNE
Abstract: front page image
(EN)A method of forming a high strength cement in a permeable starting material, the method comprising the step of combining the starting material with effective amounts of (i) a urease producing micro-organism; (ii) urea; and (iii) calcium ions and wherein the effective amount of the urease producing organism provides a urea hydrolysis rate, under standard conditions, of 0.5-50 mM urea hydrolysed.min-1.
(FR)L’invention concerne un procédé de formage d'un ciment de haute solidité dans une matière première perméable, le procédé comprenant l'étape de combinaison de la matière première avec des quantités efficaces (i) d'un micro-organisme producteur d'uréase ; (ii) d'urée ; et (iii) d'ions calcium, la quantité efficace de l'organisme producteur d'uréase présentant une vitesse d'hydrolyse de l'urée, dans des conditions standard, de 0,5 à 50 mM.min-1 d'urée hydrolysée.
