Evidence of thermophilic waste decomposition at a landfill exhibiting elevated temperature regions

Waste Management, 124, 26–35.

By: F. De la Cruz n , Q. Cheng n, D. Call n  & M. Barlaz n 

author keywords: Elevated temperature; Landfill; Methanogenic activity; Microbial community
MeSH headings : Euryarchaeota / genetics; Methane; RNA, Ribosomal, 16S / genetics; Temperature; Waste Disposal Facilities
topics (OpenAlex): Anaerobic Digestion and Biogas Production; Landfill Environmental Impact Studies; Microbial bioremediation and biosurfactants
TL;DR: This study demonstrated that from a microbiological standpoint, landfills may maintain active methanogenic processes while experiencing temperatures in the thermophilic regime (<72 °C), and microbial community shifts in response to temperature perturbations. (via Semantic Scholar)

2016 article

Hardwiring microbes via direct interspecies electron transfer: mechanisms and applications

Cheng, Q., & Call, D. F. (2016, January 1). Environmental Science Processes & Impacts, Vol. 18, pp. 968–980.

By: Q. Cheng n & D. Call n 

MeSH headings : Anaerobiosis; Bacteria / metabolism; Biodegradation, Environmental; Bioelectric Energy Sources; Biofilms; Cytochromes / metabolism; Electron Transport; Electrons; Fimbriae, Bacterial / metabolism; Genetic Engineering; Kinetics; Methane; Microbial Consortia; Microbial Interactions; Oxidation-Reduction; Waste Management
topics (OpenAlex): Microbial Fuel Cells and Bioremediation; CO2 Reduction Techniques and Catalysts; Advanced Photocatalysis Techniques
TL;DR: It is found that in most cases attempts to promote DIET in mixed culture systems do not yield the improvements expected based on defined culture studies, and areas of future research related to DIET and its application in biological treatment processes are identified. (via Semantic Scholar)
