A systematic literature review of microbial anammox consortia in UASB/ EGSB-reactors.

Anaerobic ammonium oxidation (anammox) poses an emerging research field as it can outstand previous processes of biological wastewater treatment in terms of efficiency and costs. Anammox bacteria have the ability to metabolise NH and NO to produce N under anaerobic conditions. Despite numerous studies, there is a lack of research on the co-occurrence and interrelationship of the predominant microbes that inhabit anammox-related processes.

Microwave-assisted organic acids and green hydrogen production during mixed culture fermentation.

Background: The integration of anaerobic digestion into bio-based industries can create synergies that help render anaerobic digestion self-sustaining. Two-stage digesters with separate acidification stages allow for the production of green hydrogen and short-chain fatty acids, which are promising industrial products. Heat shocks can be used to foster the production of these products, the practical applicability of this treatment is often not addressed sufficiently, and the presented work therefore aims to close this gap.

The highly differentiated gut of Pachnoda marginata hosts sequential microbiomes: microbial ecology and potential applications.

Insect gut microbiomes play a crucial role in the insect development and are shaped, among other factors, by the specialized insect diet habits as well as the morphological structure of the gut. Rose chafers (Pachnoda spp.; Coleoptera: Scarabaeidae) have a highly differentiated gut characterized by a pronounced hindgut dilation which resembles a miniaturized rumen.

Monitoring mouse papillomavirus-associated cancer development using longitudinal Pap smear screening.

Unlabelled: A substantial percentage of the population remains at risk for cervical cancer due to pre-existing human papillomavirus (HPV) infections, despite prophylactic vaccines. Early diagnosis and treatment are crucial for better disease outcomes. The development of new treatments heavily relies on suitable preclinical model systems.

Multivariate comparison of taxonomic, chemical and operational data from 80 different full-scale anaerobic digester-related systems.

Background: The holistic characterization of different microbiomes in anaerobic digestion (AD) systems can contribute to a better understanding of these systems and provide starting points for bioengineering. The present study investigates the microbiome of 80 European full-scale AD systems. Operational, chemical and taxonomic data were thoroughly collected, analysed and correlated to identify the main drivers of AD processes.
