We introduce DESMAN for De novo Extraction of Strains from Metagenomes. Large multi-sample metagenomes are being generated but strain variation results in fragmentary co-assemblies. Current algorithms can bin contigs into metagenome-assembled genomes unable to resolve strain-level variation. identifies variants core genes and uses co-occurrence across samples link haplotypes abundance profiles. These then searched against non-core determine the accessory genome each strain. validated on a...
Abstract Microbial metabolism upholds a fundamental role in the sustainability of water ecosystems. However, how microorganisms surviving low-concentration substrate environments, including existence emerging compounds interest, remains unclear. In this review, microbial strategies for concentrating, utilizing, and metabolizing low concentration substrates were summarized. Microorganisms develop substrate-concentrating at both cell aggregate levels substrate-limited settings. Following,...
Culture-independent, molecular techniques were applied to the characterization of microbial communities an anaerobic granular sludge obtained from a full-scale digester. Procedures optimised for total DNA recovery and polymerase chain reaction (PCR) amplification 16S rDNA using archaea- eubacteria-specific oligonucleotide primers. Cloned PCR products subsequently screened by amplified restriction analysis identify operational taxonomic units (OTUs). Inserts clones representing each OTU...
The anaerobic biological treatment of volatile fatty acid (VFA) - and sucrose based wastewaters was investigated in two bioreactors, R1 R2, over a 300-day trial period. During the trial, operating temperature both reactors lowered, stepwise fashion, from 37 to 16 degrees C. VFA-fed reactor maintained an excellent level performance, regardless temperature, reaching COD removal efficiencies 95% at 18 C, biogas methane content excess 70% imposed OLR 20 kg m(-3) d(-1). However, increase applied...
Nitrogen (N) loss rates were determined in permeable sediments of the Wadden Sea using a combination stable N isotope incubation experiments and model simulation approaches during three seasons. Three different methods that employed pairing technique used: intact core incubations simulating either (1) diffusive or (2) advective transport conditions (3) slurry incubations. from under simulated exceeded those measured by 1–2 orders magnitude, but comparable to observed generally showed little...
In this study, the biokinetics of autotrophic denitrification with biogenic S0 (ADBIOS) for treatment nitrogen pollution in wastewaters were investigated. The used S0, a by-product gas desulfurization, was an elemental microcrystalline orthorhombic sulfur median size 4.69 µm and specific surface area 3.38 m2/g, which made particularly reactive bioavailable. During denitritation, biomass enriched on nitrite (NO2–) capable degrading up to 240 mg/l NO2–-N denitritation activity 339.5 mg...
