“…A number of cultures and organisms can perform MICP, with varying degrees of calcium carbonate mineralization efficiency, and include autotrophs such as Cyanobacteria, Synechococcus , and Prochlorococcus and heterotrophs such as Sporosarcina pasteurii ( Bacillus sphaericus ), B. megaterium, B. subtilis, B . cereus, B. cohnii, B. pseudofirmus, B. alkalinitrilicus, Diaphorobacter nitroreducens, Pseudomonas aeruginosa, Desulfovibrio brasiliensis, Desulfovibrio vilgaris, B. mucilaginous [10, 6]. Among this wide spectrum of axenic and non-axenic cultures that can produce carbonate ions and precipitate calcium carbonate in alkaline conditions, Lysinibacillus sphaericus , formerly known as B. sphaericus , has abilities that make this species a favorable biological component in MICP activities such as: forming long-lasting spores even more than 50 years in environmentally harsh conditions [6], creating rhombohedral and tightly crystal-packed layers, having high rates of urea hydrolysis and calcium carbonate precipitation, and precipitating bio-minerals based on both urea hydrolysis and denitrification pathways [2, 11, 12, 13, 14, 5].…”

In order to identify appropriate environmental conditions and media components that are either essential or that enhance its growth and Microbial induced calcium carbonate precipitation (MICP) activity, in this study, a series of experiments were conducted to investigate the effects of media components and oxygen conditions on the growth rate and MICP activity of Lysinibacillus sphaericus strain MB 284. From these experiments, it was observed that aerobic conditions could lead to increased calcium carbonate production and up to three times faster growth rates by strain MB284 when compared to anoxic conditions. It was also determined that considering the measured growth rate, final biomass concentration, ureolysis activity, amount of calcium carbonate precipitation, and cost of media components for designing undefined culture media for industrial applications, yeast extract is the most economically appropriate option. In our attempts to grow strain MB284 in urea, sucrose, and ammonium acetate as its sole carbon source in minimal media, it was observed it is auxotrophic and that casamino acids and casein are essential for its growth. Even though our experiments agree with the literature that the addition of urea enhances the growth and MICP activity of L. sphaericus, it was discovered that when the initial urea concentration was greater than 3 g/l, the growth rate of strain MB284 can be temporarily inhibited until enough cells and urease are produced. These results reveal that the growth and MICP activity of strain MB284 during its application for bio-self healing can be highly dependent on environmental and nutrient conditions.

Self-healing concrete designs can protect against deterioration and improve durability. However, there is no unified conclusion regarding the effective preparation and mechanical properties of self-healing concrete. In this paper, microcapsules are used in cement-based materials, the reasonable dosage of microcapsules is determined, and the self-healing performance of the microcapsule self-healing system under different curing agents is explored. The microcapsules and curing agent are shown to enhance the flexural and compressive strength of mortar specimens at relatively low contents. The optimal microcapsule content in terms of compressive strength is 1–3%. When the content of the microcapsule reaches 7%, the strength of the specimen decreases by approximately 30%. Sodium fluorosilicate is better-suited to the microcapsule self-healing cement-based system than the other two fluorosilicates, potassium fluorosilicate and magnesium, which have similarly poor healing performance as curing agents. Healing time also appears to significantly influence the microcapsule self-healing system; mortar specimens that healed for 28 days are significantly higher than those that healed for 7 days. This work may provide a valuable reference for the design and preparation of self-healing cementitious composite structures.

“…Over the years, with the continuous advancement in the field of science and technology, along with the widening of the field of intrinsic self-healing materials [112][113][114][115][116][117] , more and more novel healing systems have emerged, for instance, the realization of rupture and regeneration based on double or multiple hydrogen bonds. Self-healing systems, reversible reactions based on the thermal effect of disulfide bonds to achieve selfhealing systems, and systems that perform chemical reactions based on the energy provided by ultraviolet light to achieve self-healing [118][119][120][121] , etc.…”

Self-healing polymer is a kind of functional polymer materials that can repair scratches, cracks and other mechanical damage, whose unique self-healing ability is of great significance for prolonging the life of materials. Eigen self-healing polymers have become the focus of current research due to their advantages of mild healing conditions and repeatable healing. In this paper, the preparation technology and properties of self-healing elastomers were reviewed, which provided guidance for the preparation of polymers with high repair efficiency and pointed out its future development trend. The self-healing polymer materials based on Diels-Alder reaction, metal bond, hydrogen bond, ionic bond, disulfide bond, etc., are mainly introduced, and their preparation process, healing mechanism and healing properties are reviewed. Although much progress has been made in self-healing elastomers based on different dynamic bonds, the development of materials with high repair efficiency remains a huge challenge. In this paper, various repair pathways of self-healing elastomers were reviewed, which provided guidance for the balance between repair and mechanical properties. The development of inherently self-healing polymers was also prospected.
