The growth and metabolism of photosynthetic bacteria play a significant role in the efficiency substrate energy conversion photo-fermentation biohydrogen production (PFHP). In this paper, influence different concentrations L-alanine (0.3–1.2 g/L), L-leucine (0.6–1.5 L-serine (1–2.5 g/L) on PFHP microbial were investigated. results showed that sole additions at 0.6 g/L, 0.9 1.5 g/L to could enhance cumulative 260 ± 4.01 mL (39.04% increase), 267 4.27 (42.78% 248 3.97 (32.62% respectively. An analysis scatter matrix plots indicated three amino acid additives key increasing hydrogen production. This study helps further explore effect acid-based PFHP.

Anaerobic digestion is an important technology for energy recovery from organic waste. However, methanogenesis restricted by some barriers, such as the low-speed bottleneck of interspecies electron transfer (IET), low hydrogen partial pressure limitation, trace element deficiency, etc., resulting in poor system stability and methane production. Recently, multiple iron accelerants have been employed to overcome above challenges proven effective enhancing methanogenesis. This study reviews effects (Fe0, Fe3O4 magnetite, Fe2O3 hematite, salts other accelerants) on anaerobic terms production, process microbial community elaborates mechanisms mediating direct (DIET) syntrophic methanogenic community, strong reducibility promoting methanogenesis, provision nutrient elements microorganisms, etc. The potential engineering application current research advances regarding environmental impacts are also summarized. Although exhibit positive digestion, most focuses laboratory small-scale investigations, its large-scale should be further verified. Future focus elucidating developing diverse methods different types systems, optimizing applications, exploring high-efficiency strategies accelerants.

Additives for anaerobic digestion (AD) can play a significant role in optimizing the process by increasing biogas production, stabilizing system, and improving digestate quality. The of additives largely boils down to, among others, enhancing direct interspecies electron transfer (DIET) between microbial communities, resulting improved syntrophic interactions, adsorption toxic substances that may inhibit activity, stability accelerating decomposition complex organic materials, thereby rate hydrolysis. Through aforementioned action, significantly affect AD performance. function these materials varies, from activity to maintaining optimal conditions protecting system inhibitors. choice should be carefully tailored specific needs digester maximize benefits ensure sustainability. In light considerations, this paper characterizes most commonly used their combinations based on comprehensive review recent scientific publications, including report results conducted studies. publication features chapters describe carbon-based conductive metal oxide nanomaterials, trace metal, biological additives, enzymes microorganisms. It concludes with summarising reports various discussing functional properties, as well advantages disadvantages. presented is substantive concise analysis latest knowledge process. application characterized great potential; hence, subject matter very current future-oriented.

This study examined the hybrid adsorption and anaerobic biodegradation processes of phenol by using activated carbon cloth (CC) to stimulate direct interspecies electron transfer (DIET). Phenol was tested over three sequential runs 100 mL lab-scale bioreactors compared with two different types CC granular carbons (GAC). The addition adsorbents significantly accelerated methane production rate. high rate also accompanied complete removal phenol, a COD(s) about 95%, 43.68% 48.65% in control sets first second runs, respectively. enhancement is attributed synergy processes. An initial stage has contributed significant rapid reduction leading lower inhibition effect followed adsorbed stimulated DIET process. Specifically, optimal concentration for Single Weave (CCSW) 1.6 g L-1 promoted both Microbial community composition analysis revealed that CCSW facilitated growth syntrophic bacterial groups (Rikenellae, Syntrophorhabdaceae, Gracilibacteraceae, DTU014), archaea (Methanosaetaceae Methanoregulaceae), previously reported as key players promote degradation. To best our knowledge, this work demonstrates contribution mechanism synergistically combined process enhanced removal.
