The paper reports the results of experimental and numerical studies vortex motion in an industrial-scale glass bioreactor (volume, 8.5 L; reactor vessel diameter D, 190 mm) filled 50–80%. model culture medium was a 65% aqueous glycerol solution with density ρg = 1150 kg/m3 kinematic viscosity νg 15 mm2/s. methods particle image velocimetry adaptive track visualization allow one to observe measu...

Objective(s):The present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. Materials and Methods:The HPLC method was carried out by using a C18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...

Lilium ledebourii (Baker) Boiss. (Liliaceae) is a critically endangered lily species native tonorthern Iran, where it is protected by law. In order to develop a cost effective method for largescalepropagation, the effects of three culture systems (solid, liquid and temporary immersion)and two types of cytokinins [6-Benzyladenine (BA) and Thidiazuron (TDZ)] were studied onthe in vitro plant rege...

Abstract The laundry business sector is expanding quickly nowadays. However, the industry still dealing with issue of processing detergent wastewater. Anaerobic and aerobic bioreactors may efficiently solve this problem. This narrative review aims to assess feasibility using anaerobic for wastewater treatment. Its advantages disadvantages idea combining multi-media filtration UV light in treatm...

The characterizations of vegetable oil wastewater (VOW) are unpleasant odor, dark color, and high organic contents, including large amounts of oil and grease (O&G), chemical oxygen demand (COD), fatty acids and lipids. Therefore, VOWs should be treated efficiently to avoid the environment pollution. The aim of present study was the investigation of VOW biological treatment using membrane biorea...

Bottom-up approach is a potentially useful tool for hydrogel assembly of cell-laden individual building blocks. In this article, we assembled individual building blocks of photocrosslinkable microgels in a rapid and controlled manner. Individual building blocks of poly(ethylene glycol) (PEG) microgels with square and hexagonal shapes were fabricated by using a photolithography technique. Indivi...

In a bioreactor landfill, waste biodegradation, generation of gas and leachate, two-phase flow mechanical deformation closely couple with each other. Recirculated leachate can accelerate biodegradation landfill gas. A significant occurs due to suction change, the increase in both pressure could affect slope stability decrease effective stress. this paper, full coupled hydro-mechanical-biodegrad...
