Microbial ecology of anammox bacteria in estuarine and oxygen minimum zone environments [PDF]

Anammox (anaerobic ammonium oxidation) is an environmentally significant process with great importance for global biogeochemical cycles. This process is mediated by a unique suite of phylogenetically distinct chemolithoautotrophic bacteria which ...

Biogeochemical processes and microbial diversity of the Gullfaks and Tommeliten methane seeps (Northern North Sea). [PDF]

, 2008
Fluid flow related seafloor structures and gas seeps were detected in the North Sea in the 1970s and 1980s by acoustic sub-bottom profiling and oil rig surveys.

The effect of organic loading rate on foam initiation during mesophilic anaerobic digestion of municipal wastewater sludge [PDF]

, 2011
The impact of increasing organic load on anaerobic digestion foaming was studied at both full and bench scale. Organic loadings of 1.25, 2.5 and 5 kg VS m(-3) were applied to bench-scale digesters.

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Aerobic and Anaerobic Bacterial Isolates on the Surface and Core of Tonsils from Patients with Chronic Tonsillitis

Bengal Journal of Otolaryngology and Head Neck Surgery, 2017
Introduction Controversy regarding treatment of tonsillitis based on throat culture report still persists. If surface culture is a determinant of bacteriology of the core, then rational therapy could be aimed at organisms cultured by surface swab ...

Biotechnological aspects of anaerobic oxidation of methane coupled to sulfate reduction

, 2009
Sulfate reduction (SR) can be used for the removal and recovery of metals and oxidized sulfur compounds from waste streams. Sulfate-reducing bacteria reduce oxidized sulfur compounds to sulfide.

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

Advanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...

Investigation of some anaerobic bacteria in the sputum of cystic fibrosis patients and healthy people in Tehran, Iran [PDF]

Journal of Krishna Institute of Medical Sciences University
Background: In Cystic Fibrosis (CF) patients, increased mucus secretion and accumulation due to genetic defect leads to decreased oxygen levels and colonization of anaerobic bacteria. Aim and Objectives: In addition to investigating the difference in the

The depth specific significiance, relative abundance and phylogeography of anaerobic ammonium oxidation (anammox) in marine and estuarine sediments

, 2009
PhDThe availability of fixed forms of nitrogen is critical to the regulation of primary production. Until recently, denitrification (the sequential reduction of NO3 -, through NO2 - , to di-nitrogen gas) was recognised as the only significant pathway
