“…Enzymes identified from the genus have been demonstrated to be useful for food and pharmaceutical production, in addition to textile and paper processing. Additionally, their fermentative physiology is now being investigated for the formation of metal nanoparticles [145,146] and heavy metal reduction [147]. More so now than ever with the benefit of genome sequences and the availability of functional genomics and genetics tools, this non-model environmental genus has the potential to move from the bench to a larger scale as a biotechnological platform microorganism.…”

Plant polysaccharides continue to serve as a promising feedstock for bioproduct fermentation. However, the recalcitrant nature of plant biomass requires certain key enzymes, including cellobiohydrolases, for efficient solubilization of polysaccharides. Thermostable carbohydrate-active enzymes are sought for their stability and tolerance to other process parameters. Plant biomass degrading microbes found in biotopes like geothermally heated water sources, compost piles, and thermophilic digesters are a common source of thermostable enzymes. While traditional thermophilic enzyme discovery first focused on microbe isolation followed by functional characterization, metagenomic sequences are negating the initial need for species isolation. Here, we summarize the current state of knowledge about the extremely thermophilic genus Caldicellulosiruptor, including genomic and metagenomic analyses in addition to recent breakthroughs in enzymology and genetic manipulation of the genus. Ten years after completing the first Caldicellulosiruptor genome sequence, the tools required for systems biology of this non-model environmental microorganism are in place.

“…In the cultures with, and without, Pd, MO (100 mg/L) was degraded within 30 min and in over 6 h, respectively. Diatrizoate (20 mg/L) was degraded within 10 min in cultures with Pd (Shen et al 2015). The degradation of MO and diatrizoate were both enhanced by Pd.…”

“…The Pd 0 particles were well dispersed by cells of C. saccharolyticus and showed a better catalytic activity than chemical Pd 0 without dispersant The diameter of most Pd 0 particles formed in the presence of cells is under 100 nm. These Pd 0 particles are polyporous and homogeneous (Shen et al 2015).…”

Some thermophiles and psychrophiles have developed the ability to resort to specific defense mechanisms to quell stresses like toxicity of heavy metal ions or metals. Some of them could survive and grow even at high metal ion concentrations and are capable of binding large quantities of metallic cations. Moreover, some of these microorganisms are able to synthesize nanoparticles. The remarkable ability of these group of microbes to reduce heavy metal ions make them one of the best candidates for nanoparticle synthesis. In this chapter, thermophilic and psychrophilic microorganisms used in nanoparticle biosynthesis are presented. The aim of chapter is to make a reflection on the current state and future prospects and especially the possibilities and limitations of the use of extremophiles in bio-based technique for industries.
