Nanoengineered cellulosic biohydrogen production via dark fermentation: A novel approach. Biotechnol Adv. 2019 Apr 20;: Authors: Srivastava N, Srivastava M, Malhotra BD, Gupta VK, Ramteke PW, Silva RN, Shukla P, Dubey KK, Mishra PK Abstract The insights of nanotechnology for cellulosic biohydrogen production through dark fermentation are reviewed. Lignocellulosic biomass to sugar generation is a complex process and covers the most expensive part of cellulose to sugar production technology. In this context, the impacts of nanomaterial on lignocellulosic biomass to biohydrogen production process have been reviewed. In addition, the feasibility of nanomaterials to implement in each step of the cellulosic biohydrogen production is discussed for economic viability of the process. Numerous aspects such as possible replacement of chemical pretreatment method using nanostructured materials, use of immobilized enzyme for a fast rate of reaction and its reusability along with long viability of microbial cells and hydrogenase enzyme for improving the productivity are the highlights of this review. It is found that various types of nanostructured materials e.g. metallic nanoparticles (Fe°, Ni, Cu, Au, Pd, Au), metal oxide nanoparticles (Fe2O3, F3O4, NiCo2O4, CuO, NiO, CoO, ZnO), nanocomposites (Si@CoFe2O4, Fe3O4/Alginate) and graphene-based nanomaterials can influence different parameters of the process and therefore may perhaps be utilized for...
