“…Microbial induced calcite precipitation (MICP) is considered for several applications, such as soil reinforcement and restoration of construction materials like limestone or concrete 1 , 2 , metal and radionuclide remediation 3 – 5 and CO sequestration 6 . Precipitation based on the presence of carbonate can be caused by a multitude of metabolic pathways like photosynthesis, denitrification or sulphate reduction 7 , 8 . However, precipitation induced by ureolysis is especially promising as carbonate is produced directly alongside with ammonium ions by hydrolysis of urea 9 .…”

Microbial induced calcite precipitation (MICP) based on ureolysis has a high potential for many applications, e.g. restoration of construction materials. The gram-positive bacterium Sporosarcina pasteurii is the most commonly used microorganism for MICP due to its high ureolytic activity. However, Sporosarcina pasteurii is so far cultivated almost exclusively in complex media, which only results in moderate biomass concentrations at the best. Cultivation of Sporosarcina pasteurii must be strongly improved in order to make technological application of MICP economically feasible. The growth of Sporosarcina pasteurii DSM 33 was boosted by detecting auxotrophic deficiencies (L-methionine, L-cysteine, thiamine, nicotinic acid), nutritional requirements (phosphate, trace elements) and useful carbon sources (glucose, maltose, lactose, fructose, sucrose, acetate, L-proline, L-alanine). These were determined by microplate cultivations with online monitoring of biomass in a chemically defined medium and systematically omitting or substituting medium components. Persisting growth limitations were also detected, allowing further improvement of the chemically defined medium by the addition of glutamate group amino acids. Common complex media based on peptone and yeast extract were supplemented based on these findings. Optical density at the end of each cultivation of the improved peptone and yeast extract media roughly increased fivefold respectively. A maximum OD600 of 26.6 ± 0.7 (CDW: 17.1 ± 0.5 g/L) was reached with the improved yeast extract medium. Finally, culture performance and media improvement was analysed by measuring the oxygen transfer rate as well as the backscatter during shake flask cultivation.

“…CaCO 3 , for instance, can present many different morphological variations, such as calcite, aragonite, and vaterite, [186] and it can change depending on stimuli. [187] Ideal CaCO 3 morphology for this application is calcite, [188][189][190] which should be controlled somehow. Here, further details about these specifications were not addressed, but they will be in future research.…”

Concrete structures repair results in substantial economic and environmental issues. So, new technologies able to increase concrete lifetime are being developed. Among them, the self-healing mechanisms, which can be improved by using polymers. Thus, three different materials are synthesized to act as self-healing systems. They are: (I) cross-linked gelatin mixed with CaCO 3 (the self-healing agent); (II) a core-shell system based on the material I layered by poly(hydroxypropyl methacrylate); and (III) a second core-shell structure based on the material I covered with poly(vinyl alcohol). Cross-linking and grafting are performed using glutaraldehyde. Fourier-transform infrared spectroscopy (FTIR) proves the structure obtaining. Thermogravimetric analysis and differential scanning calorimetry prove that the materials show thermal properties that allow their use in concrete applications. Swelling degree shows that all materials swell when in contact with water. Granulometry shows the materials are mostly in the millimeter scale. Last, an aqueous media release test shows that the three tested systems did not liberate significant amounts of CaCO 3 . Therefore, both the gelatin and gelatin + polymer systems can protect the healing material, avoiding the release of the self-healing agent before the concrete cracking takes place.

“…Grande parte das bactérias é capaz de precipitar carbonato de cálcio, por meio de diversos mecanismos. Dentre eles, pode-se citar a fotossíntese oxigênica, a fotossíntese anoxigênica, a oxidação do metano e os ciclos do enxofre e do nitrogênio (Mondal et al 2019). Boa parte das pesquisas envolvendo compósitos cimentícios auto-cicatrizantes utiliza bactérias que participam do ciclo do nitrogênio e, de maneira particular, da degradação de ureia ou ácido úrico.…”

RESUMOEste trabalho explora as características, limitações e desafios de concretos autocicatrizantes pela introdução de bactérias. Uma revisão sistemática foi realizada, sobretudo, por meio da seleção de publicações dos últimos dez anos na área. Em condições favoráveis, as bactérias induzem a precipitação de carbonato de cálcio, o qual é depositado nos poros do concreto, diminuindo sua porosidade e aumentando sua resistência mecânica. O tipo de bactéria utilizado e seus nutrientes afetam diretamente os produtos formados. Bactérias ureolíticas do gênero Bacillus são o tipo mais investigado. O efeito de autocicatrização é mais pronunciado nas primeiras idades do concreto, diminuindo progressivamente ao longo do tempo. O encapsulamento ou imobilização das bactérias pode prolongar sua vida útil no meio alcalino do concreto. Palavras-chave: concreto autocicatrizante; precipitação de calcita induzida microbiologicamente; bactérias no concreto. ABSTRACTThis paper explores the caracteristics, limitations and challenges of bacteria based self-healing concrete. A systematic review was carried out by selecting publications of the last ten years on the area. Under proper conditions, bacteria induce the precipitation of calcium carbonate, which is deposited inside the concrete pores, decreasing its porosity and increasing its compressive strength. Bacteria type and its nutrientes, directly affect the precipitated products. Ureolytic bacteria, of the genus Bacillus, are the most investigated type, due to their high resistance to alcaline media. Self-healing effect is higher at early ages concretes, dropping progressively over time. In order to avoid this, bacteria are encapsulated or immobilized by protective materials, which increases theirs life cycle inside concrete's alcaline medium. Keywords: self-healing concrete; microbially induced calcite precipitation; bacteria in concrete; RESUMENEste artículo explora las características, limitaciones y desafíos de los hormigones autocurativos mediante la introducción de bacterias.
