Differential protein analysis of saline-alkali promoting the oil accumulation in Nitzschia palea.

Background: The increasingly severe salinization of the aquatic environment has led to serious damage to the habitats of aquatic organisms. Benthic diatoms are commonly employed as indicator species for assessing water quality and serve as a reflection of the overall health of the aquatic ecosystem. Nitzschia palea is a common diatom found in freshwater, with high oil content, rapid reproductive rate, and it is a commonly dominant species in various rivers.

Exenatide Attenuates Obesity-Induced Mitochondrial Dysfunction by Activating SIRT1 in Renal Tubular Cells.

Saturated free fatty acid (FFA)-induced lipotoxicity plays an important role in obesity-induced kidney injury. Exenatide, a Glucagon-like peptide-1 receptor agonist(GLP-1RA), protects against high-fat diet (HFD)-induced kidney injury. The precise mechanism needs to be further explored.

Quantitative proteomic analysis reveals the ethanologenic metabolism regulation of by exogenous ethanol addition.

Background: H-ethanol-coproducing bacteria, as primary fermenters, play important roles in the microbiome of bioreactors for bioenergy production from organic wastewater or solid wastes. YUAN-3 is an anaerobic ethanol-H-fermenting bacterium. Ethanol is one of the main end-products of strain YUAN-3 that influence its fermentative process.

Magnet anode enhances extracellular electron transfer and enrichment of exoelectrogenic bacteria in bioelectrochemical systems.

Background: Optimizing the ability of exoelectrogens is a key factor in boosting the overall efficiency of bioelectrochemical systems. In this study, we construct magnetic microbial fuel cells (MFCs) with magnets with different static magnetic field (SMF) intensities for use as anodes. It is proposed as an in situ study of the effects of magnetic fields on the performance and exoelectrogenic biofilm of bioelectrochemical system.

Insights on acetate-ethanol fermentation by hydrogen-producing Ethanoligenens under acetic acid accumulation based on quantitative proteomics.

Ethanoligenens, a novel ethanologenic hydrogen-producing genus, is a representative fermenter in its unique acetate-ethanol fermentation and physiology. Acetic acid accumulation is one of major factors that affect H-ethanol co-production. However, sufficient information is unavailable on the tolerance mechanisms of hydrogen-producing bacterium in acetic acid stress.

Dual-Edged Character of Quorum Sensing Signaling Molecules in Microbial Extracellular Electron Transfer.

Quorum sensing (QS) is a central mechanism for regulating bacterial social networks in biofilm via the production of diffusible signal molecules (autoinducers). In this work, we assess the contribution of QS autoinducers to microbial extracellular electron transfer (EET) by strain PAO1 and three mutants pure culture-inoculated in microbial electrolysis cells (MECs) and microbial fuel cells (MFCs). MECs inoculated with different strains showed a difference in current generation.

Glucose and Applied Voltage Accelerated -Nitrophenol Reduction in Biocathode of Bioelectrochemical Systems.

-Nitrophenol (PNP) is common in the wastewater from many chemical industries. In this study, we investigated the effect of initial concentrations of PNP and glucose and applied voltage on PNP reduction in biocathode BESs and open-circuit biocathode BESs (OC-BES). The PNP degradation efficiency of a biocathode BES with 0.

Response of the microbial community structure of biofilms to ferric iron in microbial fuel cells.

Ferric iron can affect the current generation of microbial electrochemical system (MES); however, how it influences microbial biofilm formation and metabolic activity has not been reported. Here, we describe the response of microbial electrode biofilm communities to insoluble ferric iron (Fe) at different concentrations in microbial fuel cells (MFCs). Insoluble ferric iron (200μM) improved electrochemical activity of the MFCs microbial biofilms during start-up and resulted in a higher maximum power density of 0.

MicroRNA-590 promotes pathogenic Th17 cell differentiation through targeting Tob1 and is associated with multiple sclerosis.

Although the exact pathogenesis of multiple sclerosis (MS) remains largely unclear, Th17 cells have been suggested as an essential regulator in the disease induction. Emerging evidence have demonstrated that noncoding RNAs, especially microRNAs (miRs), play a crucial role in modulation of Th17 cell differentiation and autoimmune disease development. Here, we revealed that miR-590 expression was markedly increased in periphery blood mononuclear cells (PBMC) and cerebrospinal fluid (CSF) of patients with MS, and positively correlated with the disease severity.

Adaptation of microbial community of the anode biofilm in microbial fuel cells to temperature.

Temperature as an important ecological factor affects biofilm development and microbial metabolic activity. Here, the performances and microbial communities of microbial fuel cells (MFCs) at different temperature were analyzed. As the temperature decreased, the power output of MFCs declined.
