“…Silica was present in both glassy amorphous and crystalline forms. The peaks at 23°, 29°, 36°, and 48° are due to the calcite phase as a major mineral in the ISA [18], while the small peaks at 33° and 35° are due to the maghemite and magnetite in the ISA. The existence of small, broader, and overlapping reflections in the diffraction pattern of ISA indicates a low-order structure (due to amorphous carbon in ISA).…”

Incense stick ash (ISA) has traces of toxic heavy metals which have an adverse effect on the environment. Every year, tonnes of ISA are disposed of in rivers and other water bodies which leads to water pollution and affects the natural water resources. ISA has several value-added minerals which could be modified or functionalized for environmental cleanup. Here, in the current research work, ISA was transformed into a flower-like noble porous material by mixing ISA and NaOH in a 1 : 1 ratio followed by calcination at 600°C for six hours in a muffle furnace. The developed material was analyzed by sophisticated instruments for the identification of the properties. The microscopic techniques revealed the micron-sized flower-like structure, while the XRD showed peaks at 30–33° which indicates the transformation of the calcite and silicate phases into new-phase mineral. FTIR also revealed bands in regions of 500–1200 cm−1 and new bands near 450 cm−1. EDS confirmed the presence of Na in the sintered product and the transformation of the ISA. Finally, the sintered product potential was assayed for the removal of methylene blue dye from wastewater using an adsorption mechanism. The removal efficiency of dye reached up to 70% within one hour only. It was found that the ISA sintered product has the potential to remove MB dye efficiently from wastewater and also reduce solid waste pollution. Microculture tetrazolium assay (MTT) and lactate dehydrogenase (LDH) assays were performed to evaluate the cytotoxicity of the sintered incense stick ash product on RTG-2 cells. The sintered incense stick ash product induced cytotoxicity on RTG-2 cells in a dose-dependent manner. Sintered ISA products have the potential to remove methylene blue dye efficiently from wastewater and reduce solid waste pollution.

Natural biomaterials originating during the growth cycles of all living organisms have been used for many applications. They span from bioinert to bioactive materials including bioinspired ones. As they exhibit an increasing degree of sophistication, natural biomaterials have proven suitable to address the needs of the healthcare sector. Here the different natural healthcare biomaterials, their biodiversity sources, properties, and promising healthcare applications are reviewed. The variability of their properties as a result of considered species and their habitat is also discussed. Finally, some limitations of natural biomaterials are discussed and possible future developments are provided as more natural biomaterials are yet to be discovered and studied.

“…Since then, the importance of cyanobacteria in carbonation has been extensively investigated, with particular regards to the molecular mechanisms driving calcite precipitation in Synechocystis spp and Synecococchus spp (Lamérand et al, 2022; Görgen et al, 2021). In the course of the years Bacillus subtilis, Pseudomonas nitroreducens and Bacillus licheniformis, Bacillus megaterium, Sporosarcina pasteurii ) (Ferral-Pérez et al, 2020; Rajasekar et al, 2021, Jarwar et al 2022) became the most studied bacteria, and widely used in practical applications as soil consolidation and concreate healing, due to their ability to produce high amount of calcite within a short period of time (Bang et al 2001; Dhami et al, 2013; Wei et al, 2015; Rajasekar et al, 2021).…”

Microbial Induced Calcite Precipitation (MICP) offers a host of interesting features, both from theoretical and practical standpoints. This process was firstly investigated as a geo-biological mechanism involved in carbonate mineral formation both in rocks and soil. The interest towards its practical use significantly increased in the recent years, as MICP was used in different fields, such as oil recovery, improvement of soil geotechnical characteristics and concreate healing. To the best of our knowledge, this paper is the first attempt to carry out a bibliometric descriptive study of publications on MICP. We analyzed data from the Web of Science Core Collection (WoSCC), which provides comprehensive information for bibliometric analysis, including the Science Citation Index-Expanded (SCI-E) and the Social Sciences Citation Index (SSCI). The bibliometric analysis was carried out on 1580 publications, from 2000 to August 2022, and included publication output, author, institution, country, collaborations between authors, institutes and countries, and citation frequency. We created visualization maps including research collaborations by using the VOSviewer program. MICP, carbonate precipitation, cementation, and soil improvement in terms of geotechnical properties are high-frequency used keywords. Although in the year 2000 only two papers were published on MICP, the number of publications increased rapidly since 2014. In 2021, 333 papers were published. China leads as the most productive country, followed by USA and Australia. According to our results, the number of research papers dramatically increased in the last 5 years. MICP with concrete healing/cementation, soil geotechnical improvement, and the low environmental impact of such a technique are becoming very popular topics among researchers. With the ageing of concrete buildings, as well as with the worsening of environmental pollution and soil alterations, the research about MICP will play an ever increasing and crucial role in civil engineering and geotechnical issues and in soil science. Nevertheless, our study pointed out a sort of concentration of the MICP studies in few countries. Russia and Brazil, for instance, seems to poorly contribute to MICP researches. A larger cooperation among countries, together with the extension of the research network on this topic, would considerably foster the progress in MICP studies, from both practical and speculative standpoints.
