Abstract:Magnetotactic bacteria (MTB) are of considerable interest because of their importance in the manufacture of various bioinspired materials. In order to find out the status of magnetotactic bacteria at three different sediment in Czech Republic, samples collected from both standing and running freshwaters were subjected to molecular diversity analysis by using 16S rRNA gene approach. Total community DNA from sediment sample was isolated and used for PCR, cloning and sequence analysis. Of the 24 analyzed sequence… Show more
“…[ 39–42 ] These bacteria have been observed in a wide range of ecosystems, ranging from marine sediments, lagoons, ponds, soils to some extreme environments. [ 43–47 ] Other nonbacterial prokaryotes such as sulfur‐reducing, hyperthermophilic, heterotrophic archaea can also produce greigite. [ 48 ] The earliest reports of magnetotactic bacteria (MTB) in 1963 [ 49 ] and 1975 [ 50 ] pioneer the discovery of MTB with diverse morphology, including cocci, spirilla, vibrios, ovoid bacteria, rod‐shaped bacteria, and multicellular bacteria.…”

Bacteria play an important role in the calcification process of natural minerals and within organisms ( Table 1). It is Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.
