“…It was observed that large aggregates of HA were detected on the cell surface. 20 , 30 Some HA enters the interior of cells and causes damage to the EPS components. 34 The EPS produced by MCB could trap most of the HA, thus interfering with material transfer and affecting electron transport.…”

“… 21 16S rRNA gene sequencing was performed using Illumina MiSeq high-throughput sequencing technology for the reactors at the end of H 2 production, and the sequences were resolved at the genus level to analyze HPB diversity. 20 Further, the sludge with HA samples was processed and collected after fermentation. The interactions between HA and HPB were revealed by scanning electron microscopy (SEM, SU8010,) and transmission electron microscopy (TEM, H-7650).…”

Hydroxyapatite (HA) had the effect of maintaining the pH balance of the reaction system and promoting enzyme activity. In this work, hydroxyapatite was synthesized by coprecipitation and characterized for biohydrogen (bioH 2 ) production from glucose. The highest bioH 2 yield obtained was 182.33 ± 2.41 mL/g glucose, amended with an optimal dosage of 400 mg/L HA, which was a 55.80% higher bioH 2 yield compared with the control group without any addition. The results indicated that HA facilitated the deterioration of organic substances and increased the concentration of soluble microbial products (SMPs). Microbial community analysis revealed that HA significantly increased the abundance of Firmicutes from 35.27% (0 mg/L, HA) to 76.41% (400 mg/L, HA), which played an essential role in bioH 2 generation. In particular, the abundance of Clostridium sensu stricto 1 increased from 15.33% (0 mg/L HA) to 45.17% (400 mg/L HA) and became the dominant bacteria. The results also indicated that HA likely improves bioH 2 production from organic wastewater in practice.

“…Biohydrogen concentration grew exponentially with increase in concentration of iron nanoparticles. Requirement of optimum nanoparticle concentration was shown in a study by Zhang et al 151 . It was observed that with moderate concentration of nickel, iron hybrid nanoparticles (~100 mg/L), gave better hydrogen yield whereas excess nanoparticle concentration inhibited the H2 production.…”

“…This can be explained by combinations of different metal-containing nanoparticles promoting elec-trical conductivity and thus accelerating the transfer of electrons to the hydrogenase active site during bioH 2 production [28]. Ferredoxin is an important redox mediator, assisting the conversion of pyruvate to acetic acid and CO 2 [29]. Here, the reactor supplemented with iron attained the highest yield (91.56 ml H 2 /gVS load), followed by R Co (80.77 ml H 2 /gVS load), R MIX (72.74 ml H 2 /gVS load), R Ni (65.63 ml H 2 /gVS load), R Zn (40.32 ml H 2 /gVS load), and R CTRL (38.19 ml H 2 /gVS load) (Figure 3B).…”

The present study reports the mixed culture acidogenic production of biohydrogen and carboxylic acids (CA) from brewery spent grains (BSG) in the presence of high concentrations of cobalt, iron, nickel, and zinc. The metals enhanced biohydrogen output by 2.39 times along with CA biosynthesis by 1.73 times. Cobalt and iron promoted the acetate and butyrate pathways, leading to the accumulation of 5.14 gCOD/L of acetic and 11.36 gCOD/L of butyric acid. The production of solvents (ethanol + butanol) was higher with zinc (4.68 gCOD/L) and cobalt (4.45 gCOD/L). A combination of all four metals further enhanced CA accumulation to 42.98 gCOD/L, thus surpassing the benefits accrued from supplementation with individual metals. Additionally, 0.36 and 0.31 mol green ammonium were obtained from protein‐rich brewery spent grain upon supplementation with iron and cobalt, respectively. Metagenomic analysis revealed the high relative abundance of Firmicutes (>90%), of which 85.02% were Clostridium, in mixed metal‐containing reactors. Finally, a significant correlation of dehydrogenase activity with CA and biohydrogen evolution was observed upon metal addition.
