Abstract Propionate is a key intermediate in anaerobic digestion processes and often accumulates association with perturbations, such as elevated levels of ammonia. Under conditions, syntrophic ammonia-tolerant microorganisms play role propionate degradation. Despite their importance, little known about these cross-species interactions. Here, we present metagenomes metatranscriptomic data for novel thermophilic bacteria the partner methanogens enriched propionate-fed reactors. A metagenome...
The objective was to determine the effects on rumen microbiome and milk quality of reducing methane (CH 4 ) produced from enteric fermentation by addition Asparagopsis taxiformis (AT) diets dairy cows. Six Nordic Red cows at 122 ± 13.7 (mean SD) days in milk, parity 2.7 0.52 producing 36 kg 2.5 per day start trial were divided into three blocks yield assigned an extra-period Latin-square change-over design comprising two dietary treatments. An extra period observation added control for...
Summary To enrich syntrophic acetate‐oxidizing bacteria ( SAOB ), duplicate chemostats were inoculated with sludge from acetate oxidation SAO )‐dominated systems and continuously supplied (0.4 or 7.5 g l −1 ) at high‐ammonia levels. The operated under mesophilic (37°C) thermophilic (52°C) temperature for about six hydraulic retention times HRT 28 days) sampled over time. Irrespective of temperature, a methane content 64–69% effluent level 0.4–1.0 recorded in fed high acetate. Low production...
Summary Inefficient syntrophic propionate degradation causes severe operating disturbances and reduces biogas productivity in many high‐ammonia anaerobic digesters, but propionate‐degrading microorganisms these systems remain unknown. Here, we identified candidate ammonia‐tolerant propionate‐oxidising bacteria using enrichment at high ammonia levels (0.7–0.8 g NH 3 L −1 ) continuously‐fed reactors. We reconstructed 30 high‐quality metagenome‐assembled genomes (MAGs) from the propionate‐fed...
The enrichment of CO2-reducing microbial biocathodes is challenging. Previous research has shown that a promising approach could be to first enrich bioanodes and then lower the potential so electrodes are converted into biocathodes. However, effect such transition on community electrode not been studied. goal this study was thus compare start-up from preenriched anodes with direct bare investigate changes in composition. three materials long-term performance also investigated. In study,...
The global spread and diversification of multidrug-resistant Gram-negative (MRGN) bacteria poses major challenges to healthcare. In particular, carbapenem-resistant Klebsiella pneumoniae strains have been frequently identified in infections hospital-wide outbreaks. most underlying resistance gene (blaKPC) has spreading over the last decade health care setting. blaKPC seems rapidly diversified found various species on different plasmid types. To review progress dynamics this diversification,...
Abstract Climate change has been intensifying soil drying and rewetting cycles, which can alter the microbiome structure activity. Here we hypothesized that a drying-rewetting cycle enhances biodegradation and, hence, decreases effectiveness of nitrification inhibitors (NIs). The DMPP (3,4-Dimethylpyrazole phosphate) MP + TZ (3-Methylpyrazol Triazol) was evaluated in 60-day incubation studies under relative to constant low high moisture conditions (40% 80% water-holding capacity, WHC,...
This study evaluated the effect of whole and autolysed Yarrowia lipolytica CBS 7504 strain on growth performance, gut immunity microbiota composition in juvenile rainbow trout (Oncorhynchus mykiss). Fish were fed diets containing 2% 5% or Y. (WY AY) a 45-day trial, with no-yeast diet as control. Log2 fold change analysis showed relative abundance association certain microbial taxa respect to control such correlation between Desulfovibrionaceae WY. Moreover, at levels demonstrated synergistic...
Multiple measurements can be used to quantify the carbon dioxide (CO2) captured during enhanced rock weathering (ERW) applications. In most terrestrial applications, CO2 is dominantly stored as carbonate alkalinity inside water. Total (TA) often taken a measure of in However, contribution acids other than carbonic acid mineral dissolution and, thus, generated must studied closely reliably capture. In this study, we test how dissolved organic (DOC) impacts non-carbonate and charge...
<ns3:p>Background The optimization of enhanced mineral weathering as a carbon dioxide removal technology requires comprehensive understanding what drives weathering. These drivers can be abiotic and biotic interact with each other. Therefore, in this study, an extensive 8-week column experiment was set up to investigate 29 potential simultaneously. Methods setup included various combinations types surface areas, irrigation settings, biochar organic amendments, along biota products such...
Microbial inhibition by high ammonia concentrations is a recurring problem that significantly restricts methane formation from intermediate acids, i.e., propionate and acetate, during anaerobic digestion of protein-rich waste material. Studying the syntrophic communities perform acid conversion challenging, due to their relatively low abundance within microbial typically found in biogas processes disruption cooperative behavior pure cultures. To overcome these limitations, this study...
Abstract Acetogenic bacteria are imperative to environmental carbon cycling and diverse biotechnological applications, but their extensive physiological taxonomical diversity is an impediment systematic taxonomic studies. Acetogens chemolithoautotrophic that perform reductive fixation under anaerobic conditions through the Wood–Ljungdahl pathway (WLP)/acetyl-coenzyme A pathway. The gene-encoding formyltetrahydrofolate synthetase (FTHFS), a key enzyme of this pathway, highly conserved can be...
Abstract Acetogens play a key role in anaerobic degradation of organic material and maintaining biogas process efficiency. Profiling this community its temporal changes can help evaluate stability function, especially under disturbance/stress conditions, avoid complete failure. The formyltetrahydrofolate synthetase (FTHFS) gene be used as marker for acetogenic profiling diverse environments. In study, we developed new high-throughput FTHFS sequencing method compared it with conventional...
Phase contrast microscopy cannot give sufficient information on bacterial metabolic activity, or if a cell is dead, it has the fate to die in viable but non-growing state. Thus, reliable sensing of activity helps distinguish different categories viability. We present non-invasive instantaneous method using fluorogenic substrate for online monitoring esterase and calcein efflux changes growing wild type bacteria. The fluorescent conversion product acetoxymethyl ester (CAM) its indicates cells...
