“…The use of NPs has been increasing significantly for applications, such as protein immobilization, biosensors and biofuels production [19,22,30,42,43]. Biosensors are used for enhancing electron transfer to acceptors.…”

“…NPs can also significantly influence the microbial metabolic activity for H 2 production through similar phenomenon under aerobic condition by efficient transfer of electrons [44]. Thus, a positive effect of various NPs, including silver (Ag), gold (Au), Copper (Cu), Fe, Ni, Palladium (Pd), Silica (SiO 2 ), Titanium (Ti), activated carbon, carbon nano-tubes (CNTs) and composite were observed on BHP [19,29,30,[44][45][46][47][48][49][50][51]. Briefly, these NPs might be stimulating BHP by their surface and quantum size effect [49].…”

“…The synthesis of various types of NPs has been demonstrated using physical, chemical and biological processes for their application in the BHP [19,29,30,51,52]. Among these synthetic approaches, green synthesis of NPs through biological method using the plant leaf extract has been suggested as a suitable alternative approach over harsh conditions adopted in physical and chemical NPs synthesis processes [29,30,52]. Cu NPs (CuNPs) showed a negative influence on the H 2 production by both C. acetobutyricum NCIM 2337 and E. cloacae 811101 strains over a concentration range of 2.5-12.5 mg/l using glucose as feed [30].…”

At the lower concentration of 2.5 mg/l of CuNPs, a 3.5 and 2.9% reduction in H 2 yield was recorede as compared to controls, where the yields were 1.74 and 1.44 mol H 2 /mol hexose, respectively.…”

“…However, the biocompatibility of metal particles is a primary concern for the H 2 producers. Further, the use of biologically synthesized NPs appeared to be a more promising approach than the physical and chemically synthesized NPs [28][29][30]. In this article, we have described the potential of different types of NPs and their compositions on the BHP by pure and mixed cultures using sugars and biowastes as a feed.…”

Biological hydrogen (H) production enhancement through the use of nanoparticles (NPs) supplement in the media is being recognized as a promising approach. The NPs, including those of metal and metal oxides have shown a significant improvement in the BHP. A number of organisms as pure or mixed cultures can produce H in presence of NPs from pure sugars and biowaste as a feed. However, their H production efficiencies have been found to vary significantly with the type of NPs and their concentration. In this review article, the potential role of NPs in the enhancement of H production has been assessed in dark- and photo-fermentative organisms using sugars and biowaste materials as feed. Further, the integrative approaches for commercial applications of NPs in BHP have been discussed.

The current study comparatively evaluated the effects of silver nanoparticles (AgNPs) on fermentative bio hydrogen (bio-H 2 ) production by Clostridium beijerinckii (KTCC1737). Green synthesized AgNPs were fabricated using henna (Lawsonia inermis) and DU-C2 actinomycete in batch using different AgNPs concentrations (0, 40, 80, and 120 μg/mL). The overall results revealed that after 72 hours of AgNPs incubation with C beijerinckii, the henna mediated AgNP synthesis increased the hydrogen production rate with a hydrogen yield of 1.71 mol H 2 /mol glucose added . However, the DU-C2-mediated AgNps synthesis inhibited bio-H 2 production during the batch H 2 fermentation. Performed live/dead staining showed AgNPs effect on the bacterial culture in batch fermentation. The results indicated that the henna mediated AgNPs enhanced the bacterial cell population, meanwhile, in case of DU-C2 AgNPs, less bacterial population occurred. Thus, the present study provides a clear overview on the application of metallic NPs as H 2 production catalysts to further improve bio-H 2 production.
