A method to obtain long lengths of flexible, biaxially oriented substrates with smooth, chemically compatible surfaces for epitaxial growth high-temperature superconductors is reported. The technique uses well established, industrially scalable, thermomechanical processes impart a strong biaxial texture base metal. This followed by vapor deposition buffer layers (metal and/or ceramic) yield surfaces. Epitaxial YBa2Cu3Ox films grown on such have critical current densities exceeding 105 A/cm2...
Abstract Background Mangrove ecosystems are considered as hot spots of biogeochemical cycling, yet the diversity, function and coupling mechanism microbially driven cycling along sediment depth mangrove wetlands remain elusive. Here we investigated vertical profile methane (CH 4 ), nitrogen (N) sulphur (S) genes/pathways their potential mechanisms using metagenome sequencing approaches. Results Our results showed that metabolic pathways involved in CH , N S were mainly shaped by pH acid...
ABSTRACT The ability of Desulfovibrio vulgaris Hildenborough to reduce, and therefore contain, toxic radioactive metal waste has made all factors that affect the physiology this organism great interest. Increased salinity is an important frequent fluctuation faced by D. in its natural habitat. In liquid culture, exposure excess salt resulted striking elongation cells. Using data from transcriptomics, proteomics, metabolite assays, phospholipid fatty acid profiling, electron microscopy, we...
Interspecies hydrogen transfer between organisms producing and consuming promotes the decomposition of organic matter in most anoxic environments. Although syntrophic coupling producers consumers is a major feature carbon cycle, mechanisms for energy recovery at extremely low free energies reactions typical these anaerobic communities have not been established. In this study, comparative transcriptional analysis model sulfate-reducing microbe, Desulfovibrio vulgaris Hildenborough, suggested...
Abstract Mangrove roots harbor a repertoire of microbial taxa that contribute to important ecological functions in mangrove ecosystems. However, the diversity, function, and assembly root-associated communities along continuous fine-scale niche remain elusive. Here, we applied amplicon metagenome sequencing investigate bacterial fungal among four compartments (nonrhizosphere, rhizosphere, episphere, endosphere) roots. We found different distribution patterns for both all root compartments,...
Abstract Microorganisms play important roles in the biogeochemical cycling of sulphur (S), an essential element Earth's biosphere. Shotgun metagenome sequencing has opened a new avenue to advance our understanding S microbial communities. However, accurate metagenomic profiling communities remains technically challenging, mainly due low coverage and inaccurate definition gene families public orthology databases. Here we developed manually curated database (SCycDB) profile functional genes...
The effects of a blend encapsulated organic acids with essential oils (EOA) as an alternative to antimicrobial growth promoter (AGP) on performance and gut health Eimeria spp./Clostridium perfringens (C. perfringens) in chickens infected necrotic enteritis (NE) broilers was investigated. A total 432 male Arbor Acres (1-day-old) were randomly distributed into 6 treatment groups, namely noninfected negative control (A); NE-infected positive (D); broiler fed basal diet supplemented 250 mg/kg...
Methane is a critical greenhouse gas with significant impacts on environmental and global change. However, CH4 cycling processes coupling mechanisms the biogeochemical of carbon, nitrogen, sulfur metals in environment remain elusive. To fill such knowledge gaps, we constructed manually curated methane database (MCycDB) for comprehensive accurate analysis microbial communities. MCycDB contains 298 gene families covering 10 metabolism pathways 610,208 representative sequences, associated...
ABSTRACT Anaeromyxobacter dehalogenans strain 2CP-C has been shown to grow by coupling the oxidation of acetate reduction ortho -substituted halophenols, oxygen, nitrate, nitrite, or fumarate. In this study, was also found Fe(III) acetate, making it one few isolates capable growth both metal and chlororespiration. Doubling times for 9.2 10.2 h were determined 2-chlorophenol reduction, respectively. These using rate [ 14 C]acetate uptake into biomass. compounds used include ferric citrate,...
ABSTRACT Desulfovibrio vulgaris Hildenborough belongs to a class of sulfate-reducing bacteria (SRB) and is found ubiquitously in nature. Given the importance SRB-mediated reduction for bioremediation metal ion contaminants, ongoing research on D. has been direction elucidating regulatory mechanisms this organism under variety stress conditions. This work presents global view organism's response elevated growth temperature using whole-cell transcriptomics proteomics tools. Transcriptional...
ABSTRACT The responses of the anaerobic, sulfate-reducing organism Desulfovibrio vulgaris Hildenborough to low-oxygen exposure (0.1% O 2 ) were monitored via transcriptomics and proteomics. Exposure 0.1% caused a decrease in growth rate without affecting viability. Concerted upregulation predicted peroxide stress response regulon (PerR) genes was observed exposure. Several candidates also showed increases protein abundance. Among remaining small number transcript changes transmembrane...
ABSTRACT Modern methods to develop microbe-based biomass conversion processes require a system-level understanding of the microbes involved. Clostridium species have long been recognized as ideal candidates for involving and production various biofuels other industrial products. To expand knowledge base clostridial relevant current biofuel efforts, we sequenced genomes 20 spanning multiple genera. The majority fall within class III cellulosome-encoding V saccharolytic Thermoanaerobacteraceae...
