This paper presents a hypothesis on the importance of initial microbial adhesion in overall process biofilm formation. The is based realization that dynamic shear conditions exist many environments, such as oral cavity, or rocks and ship hulls. Recognizing an entire detached during high once bond between initially adhering organisms surface (often constituted through so-called 'conditioning film') broken, it becomes clear research should focus detachment rather than adhesion. Experiments...
Anaerobic digestion is a common technology to biologically stabilize wasted solids produced in municipal wastewater treatment. Its efficiency usually evaluated by calculating the reduction volatile solids, which assumes no biomass growth associated with digestion. To determine whether this assumption valid and further evaluate efficiency, study sampled 35 digester sludge from different reactors at multiple time points together feed full-scale water reclamation plant Chicago, Illinois. The...
Current understanding of amino acid (AA) degraders in anaerobic digesters is mainly based on cultured species, whereas microorganisms that play important roles a complex microbial community remain poorly characterized. This study investigated short-term enrichments degrading single AAs using metagenomics and metatranscriptomics. Metagenomic analysis revealed populations related to AA had an abundance <2.5% the sequences. In contrast, metagenomic-assembled bins uncultured Bacteroidales...
Abstract Background Current understanding of the carbon cycle in methanogenic environments involves trophic interactions such as interspecies H 2 transfer between organotrophs and methanogens. However, many metabolic processes are thermodynamically sensitive to accumulation can be inhibited by produced from co-occurring metabolisms. Strategies for driving competing metabolisms remain unexplored. Results To uncover how anaerobes combat this conflict situ, we employ metagenomics...
Semi-Dirac cones, characterized by linear-parabolic dispersions, endow photonic crystals with many fascinating properties, such as topological transitions and anisotropic electromagnetic responses. While most preceding investigations concentrated on two-dimensional systems, our exploration of three-dimensional comprising a cubic lattice core-shell spheroids unveils unusual dispersions in systems---dual semi-Dirac cones. The dual cones arising from pair coexisting triply degenerate modes can...
Microorganisms in activated sludge (AS) play key roles the wastewater treatment processes. However, their ecological behaviors and differences from microorganisms other environments have mainly been studied using 16S rRNA gene that may not truly represent situ functions.Here, we present 2045 archaeal bacterial metagenome-assembled genomes (MAGs) recovered 1.35 Tb of metagenomic data generated 114 AS samples 23 full-scale plants (WWTPs). We found MAGs obvious plant-specific features few...
Methanogenesis has been widely accepted as an ancient metabolism, but the precise evolutionary trajectory remains hotly debated. Disparate theories exist regarding its emergence time, ancestral form, and relationship with homologous metabolisms. Here, we report phylogenies of anabolism-involved proteins responsible for cofactor biosynthesis, providing new evidence antiquity methanogenesis. Revisiting key catabolism-involved further suggests that last Archaea common ancestor (LACA) was...
Microbial community assembly in engineered biological systems is often simultaneously influenced by stochastic and deterministic processes, the nexus of these two mechanisms remains to be further investigated. Here, three lab-scale activated sludge reactors were seeded with identical inoculum operated parallel under eight different retention time (SRT) sequentially reducing SRT from 15 days 1 day. Using 16S rRNA gene amplicon sequencing data, microbial populations at start-up (15-day SRT)...
Dielectric composites are believed to tightly obey the effective-medium theory (EMT) when their dimensions much smaller compared wavelength inside them. It is naturally expected that refractive indices of a part constituent materials approach zero, validity EMT further strengthened. Here, we demonstrate breaks down in deep-subwavelength dielectric containing homogeneous epsilon-near-zero (ENZ) constituents, which contrary above intuitive picture, as validated by both Bloch-wave analysis and...
Upflow anaerobic sludge blanket (UASB) reactor has served as an effective process to treat industrial wastewater such purified terephthalic acid (PTA) wastewater. For optimal UASB performance, balanced ecological interactions between syntrophs, methanogens, and fermenters are critical. However, much of the remain unclear because have been studied at a "macro"-level perspective ecosystem. In reality, reactors composed suite granules, each forming individual micro-ecosystems treating Thus,...
The anaerobic packed-bed (AP) and hybrid (HP) reactors containing methanogenic microbial consortia were applied to treat synthetic soft drink wastewater, which contains polyethylene glycol (PEG) fructose as the primary constituents. AP HP achieved high COD removal efficiency (>95%) after 80 33 days of operation, respectively, operated stably over 2 years. 16S rRNA gene pyrotag analyses on a total 25 biofilm samples generated 98,057 reads, clustered into 2,882 operational taxonomic units...
In anaerobic digesters, temperature fluctuation could lead to process instability and failure. It is still not well understood how digester microbiota as a whole respond heat shock, what specific organisms are vulnerable perturbation or responsible for recovery after perturbation. To address these questions, mesophilic benzoate-degrading methanogenic culture enriched from was subjected different levels of shock. Three types methane production profiles were observed in comparison the control:...
