Lignocellulosic waste-streams are resources worth investigating to produce value-added bioproducts due their low-cost, renewability, versatility, and abundance. This study evaluated five Zygomycota strains as potential oleaginous microorganisms for direct bioconversion of cakes derived from the vegetable-oil-milling industry into microbial oil. Solid-state fermentation (SSF) conditions in tray ...

A flow-through biosensor consisting of a fixed bed bioreactor was employed to detect the insecticideparaoxon. Based on the inhibition of organophosphorous insecticide to the enzymatic activity of acetylcholinesterase (AChE), using paraoxon as a model compound, the condition for detection of the insecticide were optimized. The influence of enzyme loading on the packing surface was studied ...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...

Abstract This manuscript addresses the problem of controlling a bioreactor to maximize production desired product while respecting constraints imposed by nature bio‐process. The approach is demonstrated first building data‐driven model and then formulating predictive controller (MPC) with results illustrated implementing detailed monoclonal antibody (the test bed) created Sartorius Inc. In part...

The removal of formaldehyde as a toxic substance from aqueous solutions is particular importance. In this research, sequencing batch rotating-bed bioreactor (SBRB) was used on laboratory scale for biodegradation synthetic wastewater. reactor made plexiglas with cylindrical shape. Kaldnes media were placed in rotating basket the reactor. effects concentration (500–1500 mg/L), hydraulic retention...

The treatment of perchlorate-contaminated groundwater was examined using two side-by-side pilot-scale fixed-bed bioreactors packed with sand or plastic media, and bioaugmented with the perchlorate-degrading bacterium Dechlorosoma sp. KJ. Groundwater containing perchlorate (77microg/L), nitrate (4mg-NO(3)/L), and dissolved oxygen (7.5mg/L) was amended with a carbon source (acetic acid) and nutri...

Neuroblastoma is a vascularized pediatric tumor derived from neural crest stem cells that displays vasculogenic mimicry and can express a number of stemness markers, such as SOX2 and NANOG. Tumor relapse is the major cause of succumbing to this disease, and properties attributed to cancer stem-like cells (CSLC), such as drug-resistance and cell plasticity, seem to be the key mechanisms. However...
