Significance Measuring activity patterns of microbes in their natural environment is essential for understanding ecosystems and the multifaceted interactions microorganisms with eukaryotes. In this study, we developed a technique that allows fast nondestructive measurements microbial communities on single-cell level. Microbial were amended heavy water (D 2 O), treatment does not change available substrate pool. After incubation, physiologically active cells are rapidly identified Raman...
ABSTRACT Biological nitrogen fixation is an important component of sustainable soil fertility and a key the cycle. We used targeted metagenomics to study fixation-capable terrestrial bacterial community by targeting gene for nitrogenase reductase ( nifH ). obtained 1.1 million 454 amplicon sequences from 222 samples collected 4 National Ecological Observatory Network (NEON) sites in Alaska, Hawaii, Utah, Florida. To accurately detect correct frameshifts caused indel sequencing errors, we...
Viral evolution is revealed by giant viruses encoding multiple components of the protein translation machinery.
ABSTRACT Biodiversities can differ substantially among different wastewater treatment plant (WWTP) communities. Whether differences in biodiversity translate into the provision of particular ecosystem services, however, is under active debate. Theoretical considerations predict that WWTP communities with more are likely to contain strains have positive effects on rates functions, thus resulting associations between those two variables. However, if were sufficiently biodiverse nearly saturate...
Simultaneous electricity generation and distillery wastewater (DWW) treatment were accomplished using a thermophilic microbial fuel cell (MFC). The results suggest that MFCs, which require less energy for cooling the DWW, can achieve high efficiency also reduce sulfate along with oxidizing complex organic substrates. generated current density (2.3 A/m(2)) power (up to 1.0 W/m(2)) higher than previous wastewater-treating MFCs. significance of Coulombic (CE; up 89%) indicated electrical was...
The number of functional traits a wastewater treatment plant (WWTP) microbial community (i.e. richness) is thought to be an important determinant its overall performance, but the ecological factors that determine richness remain unclear. taxa within taxonomic one factor might important. Communities contain more are likely have traits, and positive association therefore expected between richness. Empirical tests for this among WWTP communities, however, lacking. We address knowledge gap by...
Abstract Bacterial communities in wastewater treatment plants (WWTPs) affect plant functionality through their role the removal of pollutants from wastewater. vary extensively based on operating conditions and influent characteristics. The capacity WWTPs can also bacterial community via variations organic or nutrient composition influent. Despite importance considering capacity, characteristics that control assembly are largely unknown. In this study, we discovered Korea Vietnam, which...
High-density polyethylene (HDPE) is a widely used organic polymer and an emerging pollutant, because it very stable nonbiodegradable. Several fungal species that produce delignifying enzymes are known to be promising degraders of recalcitrant polymers, but research on the decomposition plastics scarce. In this study, white rot fungus, Bjerkandera adusta TBB-03, was isolated characterized for its ability degrade HDPE under lignocellulose substrate treatment. Ash (Fraxinus rhynchophylla) wood...
Drought is one of the most vulnerable factors that affect crop productivity. Little known about plant-associated microbiomes and their functional roles in assisting plant growth under drought. We investigated genetic transcriptomic characteristics opportunistic beneficial microorganisms selectively alleviate stress through plant-bacteria interactions Pseudomonas fluorescens DR397 was isolated from drought-prone rhizospheric soil soybean showed high metabolic activity at -1.25 Mpa. The genome...
Modification of the outer membrane charge by a polymyxin B (PMB)-induced PmrAB two-component system appears to be dominant phenomenon in PMB-resistant Acinetobacter baumannii. variants and many clinical isolates also appeared produce vesicles (OMVs). Genomic, transcriptomic, proteomic analyses revealed that upregulation pmr operon decreased membrane-linkage proteins (OmpA, OmpW, BamE) are linked overproduction OMVs, which promoted enhanced biofilm formation. The addition OMVs from into...
We demonstrate the potential of eco-friendly nanogenerators based on (K,Na)NbO<sub>3</sub> nanorod arrays for high-output power generation at room temperature and elevated temperature.
Algicidal bacteria have received broad acceptance as an ecofriendly tool for controlling harmful algal blooms. However, their practical application is still limited to the lab-scale tests due complex alga–bacterium interactions in different nutrient statuses. In this study, Aeromonas sp. L23 that exhibit relatively wide-spectrum algicidal activity was isolated from a eutrophic agricultural lake. The physiological response of cyanobacteria and green under varied nutritional status were...
Arbuscular mycorrhizal fungi (AMF) are critical for soil ecosystem services as they enhance plant growth and quality via nutrient cycling carbon storage. Considering the growing emphasis on sustainable agricultural practices, this study investigated effects of conventional organic farming practices AMF diversity, abundance, ecological functions in maize, pepper, potato-cultivated soils. Using next-generation sequencing quantitative PCR, we assessed diversity abundance addition to health...
Although flow cytometry produces reliable results, the data processing from gating to fingerprinting is prone subjective bias. Here, we integrated autogating with Automated Machine Learning in enhance classification of bacterial phenotypes. We analyzed six strains prevalent soil and groundwater-Bacillus subtilis, Burkholderia thailandensis, Corynebacterium glutamicum, Escherichia coli, Pseudomonas putida, stutzeri. Using H2O-AutoML framework, applied gradient-boosting machine (GBM) models...
