Summary: Fe3O4 nanoparticles modified Aspergillus tubingensis mycelial pellets-based anaerobic granular sludge (Fe3O4@AT-AGS) was developed to improve the catalytic efficiency and stability of hydrogen-producing bacteria (HPB). The Fe3O4@AT-AGS protected flora and increased flora diversity and stability. The porous structure promoted the transfer from lactate-producing bacteria (LPB) to HPB. The Fe3O4@AT-AGS significantly enhanced the abundance, dehydrogenase activity, and stability of HPB.

Summary: The effect of temperature on bacterial dynamics and taxonomic structure during whey fermentation for lactic acid production was evaluated in this study. The results showed that temperatures between 37-42 degrees C were more favorable for lactic acid production and the predominant bacterial genus in whey was Lactobacillus. Additionally, the diversity of beneficial bacteria found in fresh whey presents attractive technological characteristics and offers a biotechnological option to add value to whey.

Summary: This study investigates the feasibility of producing hydrogen from acid cheese whey via lactate-driven dark fermentation (LD-DF). The results show that it is technically feasible to produce hydrogen from undiluted cheese whey through lactate oxidation-mediated fermentation. Microbial community analysis reveals that Lactobacillus, Clostridium, and Klebsiella were the dominant bacterial genera when the hydrogen production rate peaked. It is suggested that LD-DF can be a strategic hydrogen-producing pathway to be implemented with cheese whey.

Summary: This study investigated the properties of blueberry juice and whey protein gels formed by mixed fermentation. The state of the gels showed significant changes with different fermentation times. The release of polyphenols, flavonoids, and protein from the fermented gels was higher at a fermentation time of 7 hours in the in vitro digestion experiment. The whey protein fermented gels and whey protein mixed blueberry juice fermented gels should be fermented for more than 7 hours to facilitate the release of bioactive compounds in the gastric juices.

Summary: TCS undergoes degradation in sludge anaerobic fermentation, leading to a decrease in hydrogen yield, possibly due to hydrogen serving as electron donors for TCS dechlorination. Furthermore, the presence of TCS significantly inhibits acidogenesis, likely through binding of TCS's functional groups to active sites of acetate kinase.

Summary: This study investigated the coupling effect of potassium ferrate (PF) loading on steel slag (SS) on excess sludge anaerobic fermentation. Results showed that SS loading increased the treatment performance of PF on short chain volatile fatty acids (SCFAs) production from anaerobic fermented sludge. The modified PF loaded SS (MPF-SS) promoted the dissolution and release of organic substrates from intracellular to extracellular and showed a greater promotion of acid production microorganisms compared to acid consumption microorganisms. MPF-SS addition effectively reinforced carbohydrate transport, amino acid metabolism, and key enhanced genes associated with fatty acid biosynthesis pathways.

Summary: This study investigated the evolution of a Chlorella sp. monoculture into microalgal-bacterial granular sludge (M-BGS) during the treatment of liquid fraction from the dewatering of digested sewage sludge (LF-DSS) in a hybrid photo-bioreactor (H-PBR). The M-BGS reached a stable taxonomic and morphological structure after 60 days of operation, with a biomass primarily composed of Chlorella sp., Microthrix parvicella, and filamentous bacteria. The presence of a higher bacteria abundance led to a faster-growing M-BGS biomass and improved removal of TOC and COD from the LF-DSS.

Summary: Chemical toilets are becoming more prevalent, especially in tourist destinations where waste treatment systems are lacking. In this study, the viability of anaerobic digestion for chemical toilet sewage (CTS) co-fermented with maize silage biomass was tested. It was found that CTS does not hinder anaerobic digestion as long as it is not more than 30% of the diluting fluid. The biogas yield reached 400 cm(3)/gVS, with 57 +/- 2.6% methane content.

Summary: The most common technology for extracting energy and valuable materials from sewage sludge is anaerobic digestion (AD), which improves outcomes when conducted under thermophilic conditions. However, there is ongoing research to enhance the effectiveness of AD for aerobic granular sludge (AGS) with other methods. One promising method is the pre-treatment of AGS with solidified carbon dioxide (SCO2). This study evaluated the effects of SCO2 pre-treatment on AGS during thermophilic AD, examining changes in organic and biogenic compounds, biogas and methane production, and developing an empirical model for biogas production.

Summary: The conversion of organic matter into electricity is of interest to scientists worldwide, and microbial fuel cells (MFC) have been developed for this purpose. However, current MFCs do not meet the requirements for industrial-scale use due to barriers in extracellular electron transfer. Graphene, a newly developed material, shows promising results in improving electron transfer and overall output parameters. This article discusses the technologies and attempts by scientists worldwide to incorporate graphene into MFCs.
