The gut microbiota and related metabolites are positively regulated by soluble dietary fiber (SDF). In this study, we explored the effects of SDF from pear pomace (PP) on the regulation of gut microbiota and metabolism in high-fat-diet-fed (HFD-fed) C57BL/6J male mice. The results showed that PP-SDF was able to maintain the HFD disrupted gut microbiota diversity with a significant increase in _UCG-006, , and spp.

One-stage auto thermophilic aerobic digestion (ATAD) could achieve the same sludge stabilization efficiency as two- or multi-stage ATAD process does. However, the dewaterability of sludge might be affected through thermophilic digestion because of the release of intracellular substances under the thermophilic temperatures. This paper investigated which operation factors affect intracellular substances released in the liquid phase of sludge that lead to different extent of dewaterability.

- - The one-stage autothermal thermophilic aerobic digestion (ATAD) method is effective for reducing volatile solids and pathogens in sewage sludge.
- - A new process combining mesophilic anaerobic digestion with thermophilic aerobic digestion (AN/TAD) operates in a single digester designed to save aeration energy, achieving 38.1% volatile solid removal by day 16.
- - AN/TAD demonstrates improved efficiency by maintaining higher levels of total organic compounds and fatty acids during the digestion, while also promoting cellular breakdown through initial hydrolytic acidification.
