摘要： The present invention is directed to methods of preparing biocement. The methods disclosed herein employ microbial or enzymatic means first to generate acid which dissolves CaCO3, and then to degrade urea, producing CO3− ions which increase the pH and lead to the reprecipitation of CaCO3. The precipitation of CaCO3 acts as a cementation process which can bind together particulate materials to yield mortars, concretes and suchlike. The invention further provides construction materials formed by the methods of the invention, and bacterial strains which can be used in the methods of the invention to generate organic acids.

摘要： The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture (“cementious material”) nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.

摘要： The present invention relates to a method of manufacturing soil reinforced by microbe-based bio-binders and soil produced by the method. The bio-binders are not harmful to humans, do not cause environmental pollution and secure sufficiently the soil strength and resistance against wind. According to the method, the soil is prepared by binding sand whose major components are silica and alumina, ureolytic microbes, urea, calcium ion, and polymer fibers, and the content of polymer fibers in sand ranges from 0.05 wt % to 5 wt %. In addition, it is preferable that the microbes provide CaCO3 at a rate at 1˜7×10−9 g CaCO3 ppt cell−1 hr−1 under optimum conditions.
