Methanogenic Paraffin Biodegradation and the Underlying Syntrophic Relationships
… spilled. Methanogenic biodegradation through syntrophy plays an important role in their degradation, with implications for remediation and oil recovery. There is still much to learn about methanogenic biodegradation of recalcitrant hydrocarbons such as paraffinic n-alkanes, or the overall …

Syntrophic relationships between algae and bacteria in a fresh-water stream and in culture /
… evidence, in statistical correlation for syntrophy between the microbial populations. This relation is probably subject to control by the temperature and pH of the aquatic environment. Several species of a pond community were isolated in axenic culture and tests were performed to determine …

Enhancing energy recovery from industrial wastewater using microbial fuel cells
… by exploiting mutualistic relationships such as syntrophy or ability of facultative microoganisms (Saccharomyces cerevisiae) to consume residual oxygen from the anode. A coculture of Shewanella oneidensis and Clostridium beijerinckii, investigated here for the first time, gave a power production …

Pre-, pro-, and synbiotic modulation of the intestinal microbiota stimulates enteroendocrine mediated intestinal adaptation in piglets with short-bowel syndrome
… butyrate and other SCFA through microbial syntrophy. In this series of studies, we: 1) Identified key existing information related to the etiology, treatment, and physiology related to SBS and the intestinal microbiota (literature review) 2) Investigated potential interactions between …

Omics-based characterization of complex anaerobic metabolism in methanogenic wastewater treatment
Below the familiar oxygenated biosphere lay ecosystems teeming with “anaerobic” prokaryotes thriving in the absence of O2. As anaerobes exhaust compounds for favorable respiration (e.g., NO3- and SO42-), microorganisms resort to fermentation and respiration of H+ and CO2. Across Earth, microbial …

Unexpected metabolic versatility discovered using new high-throughput genetic approaches in a model methanogen
Microorganisms known as methanogens produce most of the methane on Earth and areglobally distributed in anoxic (i.e., oxygen-free) environments such as freshwater and marine sediments, wastewater treatment facilities, and the digestive tracts of ruminants. Despite acknowledgement of their broad …

Enhanced biohydrogen production and substrate utilization by co-culture fermentation with reduced extracellular electron shuttles
Hydrogen is a promising energy carrier due to no greenhouse gas (GHG) emission during combustion and the highest conversion efficiency in fuel cells and highest energy content per unit mass compared to carbon-based energy carriers. However, three key challenges for large-scale biohydrogen …

Recovering biomethane from fats, oils, and greases: Examining the impacts of microbial ecology on anaerobic codigester stability and bioconversion kinetics
Recovering biomethane with anaerobic digestion is of global interest to reduce carbon footprints and improve process economics for the treatment of organic wastes. Fats, oils, and greases (FOG) are desirable co-substrates for biomethane recovery because they have a substantially higher energy …

Haemophilus influenzae as a chassis for directed endosymbiosis
The transition from prokaryotes to eukaryotic life represents one of the most consequential events in the history of life on Earth. Through the understanding of endosymbiotic theory, namely the origins of organelles via partnerships between hosts and intracellular symbionts, this evolutionary …

Entwicklung einer Technologie zur langzeitstabilen Biologischen Reinigung schwermetallbelasteter Bergbauwässer
A new technology for biotechnological treatment of mine waters with both high concentrations of heavy metals and sulphate was developed. The technology is based on the technical coupling of microbially mediated hydrolysis, fermentation and microbial sulphate reduction in a self-stabilising process. …
