“…Large biofilms were obtained, showing the potential to be used in crack filling purposes for increasing lifespan or preventing early deterioration. Similar results were reported by Páramo Aguilera et al, who found optimal biofilm formation by using B. subtilis and B. cereus bacterial strains [67].…”

Microbiologically Induced Carbonate Precipitation in the Restoration and Conservation of Cultural Heritage Materials

Microbiologically induced carbonate precipitation (MICP) is a well-known biogeochemical process that allows the formation of calcium carbonate deposits in the extracellular environment. The high concentration of carbonate and calcium ions on the bacterial surface, which serves as nucleation sites, promotes the calcium carbonate precipitation filling and binding deteriorated materials. Historic buildings and artwork, especially those present in open sites, are susceptible to enhanced weathering resulting from environmental agents, interaction with physical-chemical pollutants, and living organisms, among others. In this work, some published variations of a novel and ecological surface treatment of heritage structures based on MICP are presented and compared. This method has shown to be successful as a restoration, consolidation, and conservation tool for improvement of mechanical properties and prevention of unwanted gas and fluid migration from historical materials. The treatment has revealed best results on porous media matrixes; nevertheless, it can also be applied on soil, marble, concrete, clay, rocks, and limestone. MICP is proposed as a potentially safe and powerful procedure for efficient conservation of worldwide heritage structures.

“…Several studies reported self-healing of cracks of (<0.5 mm) by Bacillus cohnii, B. pseudofirmus, B. subtilis, B. alkalinitrilicus, Pseudomonas aeruginosa, and Diaphorobacter nitroreducens (Jonkers et al, 2010;Wang et al, 2012Wang et al, , 2014Ersan et al, 2015;Khaliq and Ehsan, 2016). Several studies have also been conducted in the restauration of historic monuments such as Thouars church tower (Le Metayer-Levrel et al, 1999;Tiano et al, 1999), Alcázar de Guadalajara (Jroundi et al, 2014), Angera Cathedral (Perito et al, 2014), and Castillo de Chapultepec (Aguilera et al, 2015) using MICP.…”

Microbially Induced Calcium Carbonate Precipitation (MICP) and Its Potential in Bioconcrete: Microbiological and Molecular Concepts

et al. 2019

In this review, we discuss microbiological and molecular concepts of Microbially Induced Calcium Carbonate Precipitation (MICP) and their role in bioconcrete. MICP is a widespread biochemical process in soils, caves, freshwater, marine sediments, and hypersaline habitats. MICP is an outcome of metabolic interactions between diverse microbial communities with organic and/or inorganic compounds present in the environment. Some of the major metabolic processes involved in MICP at different levels are urea hydrolysis, denitrification, dissimilatory sulfate reduction, and photosynthesis. Currently, MICP directed by urea hydrolysis, denitrification, and dissimilatory sulfate reduction has been reported to aid in the development of bioconcrete and has demonstrated an improvement in the mechanical and durability properties of concrete. Bioconcrete is a promising sustainable technology which reduces negative environmental impact caused by CO 2 emissions from the construction sector, as well as in terms of economic benefits by way of promoting a self-healing process of concrete structures. Among the metabolic processes mentioned above, urea hydrolysis is the most applied in concrete repair mechanisms. MICP by urea hydrolysis is induced by a series of reactions driven by urease (Ur) and carbonic anhydrase (CA). Catalytic activity of these two enzymes depends on diverse parameters, which are currently being studied under laboratory conditions to better understand the biochemical mechanisms involved and their regulation in microorganisms. It is clearly evident that microbiological and molecular components are essential to improving the process and performance of bioconcrete.

“…Noteworthy research endeavors have extensively explored the use of diverse microorganisms like B. subtilis, BKH4 (alkaliphilic bacterium), B. pseudofirmus, Bacillus cohnii, B. alkalinitrilicus, Diaphorobacter nitroreducens, Bacillus sphaericus, and Streptococcus aureus. These microorganisms have proven effective in repairing cracks that measure less than 0.5 mm, through their targeted and specialized activities (Aguilera, et al 2015;Adzami, et al 2018;Ersan, et al 2015;Jonkers, et al 2010;Jroundi, et al 2014;Khaliq, & Ehsan, 2016;Le Metayer-Levrel, et al 1999;Perito, et al 2014;Sarkar, et al 2019;Shukla, et al 2022;Tiano, et al 1999;Wang, et al 2012).…”

Life Science can divide into many branches. In each branch, scope of research is enormous. The future of the Life Science is technology driven which help to solve many problems in the daily life. The book entitled "Trends and Technology Development in Life Sciences" provides knowledge on some recent trends and keep us updated of the same. It enhances the diagnosis; treatment of diseases and artificial intelligence perform more complex tasks. India is one of the fastest growing Life Science markets in the industry. The pandemic made this Science field to think more innovative way and to take up the challenges such as vaccine production. Manufacturing of pharmaceuticals, biotechnology-based food and medicines, medical devices, biomedical technologies, nutraceuticals, environmental science, cloud technology, etc. are important fields and research and development happening in all these branches.Collaboration is vital between academia and Life Science industry and funding is crucial for the technology development. Recent trends and technology development boost good services, simplify the processes and cost cutting. Moreover, learning the surrounding problems and interest in research can detect solution to most of the glitches. Advancement in technology is essential for the development of country and population. Study of merits and demerits are equally important in sustainable development of science.In this book, recent research techniques in different fields are included.
