A novel amino-functionalized silica-coated nanoscale zerovalent iron (NZVI@SiO2-NH2) was successfully synthesized by using one-step liquid-phase method with the surface functionalization of nanoscale zerovalent iron (NZVI) to enhance degradation of chlorinated organic contaminants from anaerobic microbial system. NZVI@SiO2-NH2 nanoparticles were synthesized under optimal conditions with the uni...

Anaerobic digestion is a process in which microorganisms degrade organic material, such as dairy manure, in the absence of oxygen to produce biogas and digestate. Biogas is composed mostly of methane, which is the main constituent of natural gas (Table 1). Digestate is the degraded organic material that exits the digester after the digestion process. Digestate contains nutrients that can be use...

The accumulation of solid organic waste is reaching critical levels in almost all regions the world. It must be managed sustainably to avoid depletion natural resources, minimize risks human health, reduce environmental burdens, and maintain an overall balance ecosystem. This research focuses on anaerobic digestion bovine swine excreta with without applying beneficial microorganisms as a viable...

A 20-ml blood sample was collected from adult patients with suspected bloodstream infections and distributed equally into the four volume-controlled bottles of a blood culture set consisting of aerobic and anaerobic BACTEC Plus/F bottles and aerobic and anaerobic BacT/Alert FAN bottles. All bottles were incubated in their respective instruments for a standard 5-day protocol or until the instrum...

Syntrophy and interspecies electron transfer among different microbial groups occurs in anaerobic digestion, many papers recently reported their positive effect on biogas methane production. In this paper, we present the results of conductive material, i.e., graphene, PAC biochar addition 3.5 L batch experiments, analyzing production curve. A peculiar curve pattern occurred presence materials. ...

background and objectives: essential oils may improve the utilization of nutrients by ruminal microorganisms. the aim of this study was to assess the effect of different doses of ajowan essential oils (aeo) on growth and fibrolytic activity of anaerobic fungi, and generic distribution of ciliated protozoa ( in vitro ). material and methods: different doses of aeo (0, 150, 300, 450 and 600 ppm) ...

The paper presents the activity of anaerobic bacterial communities isolated from soil polluted by aircraft fuel on distillery decoctions with phosphogypsum. The microorganisms were selected using the microcosms method, and then enriched on Postgate medium with ethanol. The isolated communities became the inoculum to establish a culture on potato and rye distillery decoctions. The obtained resul...

An evaluation of the Vitek Anaerobe Identification (ANI) card was performed with 341 bacterial isolates, including 313 clinical isolates and 28 stock strains of anaerobic microorganisms. Identifications obtained with the ANI card were compared with those determined by conventional methods. The card identified 73.2% of 149 anaerobic gram-negative bacilli, 63.6% of 44 Clostridium spp., 65.8% of 3...
