This study investigated the degradation and enzymatic saccharification of cornstalk by white-rot and brown rot fungi. The fungal strains Trametes pubescens Cui 7571, Trametes velutina Dai 10149, and Antrodia wangii Cui 7568 were analyzed in solid-state fermentation cultures. Various extracellular enzyme activities were assessed to determine biochemical changes during the degradation process. Fo...

We focused on the surface microstructure and morphology changes of Cu/eutectic SnBi/Cu joint during solid-state aging process through ex situ scanning electron microscopy (SEM) observations and energy dispersive X-ray spectroscopy (EDXS) analysis. Different intermetallic compound (IMC) growth behaviors on the surface from the bulk of solder joints were observed and investigated. The results ind...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

The gas-phase loading of [Zn4O(bdc)3] (MOF-5; bdc = 1,4-benzenedicarboxylate) with the volatile compound [Ru(cod)(cot)] (cod = 1,5-cyclooctadiene, cot = 1,3,5-cyclooctatriene) was followed by solid-state (13)C magic angle spinning (MAS) NMR spectroscopy. Subsequent hydrogenolysis of the adsorbed complex inside the porous structure of MOF-5 at 3 bar and 150 degrees C was performed, yielding ruth...

Dyes are widely used in various industries most of them are not readily biodegradable and are consisted of number of toxic, mutagenic, and carcinogenic compounds. Therefore, it is essential to remove them from effluent before their discharge to the environment. The objective of this investigation was to synthesize copper oxide (CuO) doped zinc oxide (ZnO) nanoparticles under mild hydrothermal c...

 Central composite orthogonal design was applied to quantify relations  of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...

this study investigates the degradation of sodium dodecylbenzenesulfonate (sdbs) in aqueous solution by the fenton-like oxidation process. the effects of different parameters such as concentrations of ferric chloride and hydrogen peroxide, ph and reaction time on the sdbs removal and chemical oxygen demand (cod) reduction were evaluated. response surface methodology (rsm) with central composite...

background and objective: lactobacillus plantarum is one of the probiotics species used in functional food products. these bacteria or their purified bacteriocins are used as biological preservatives in the food industry. the first step in production of an array of probiotic products is optimizing production in fermentors. this study aimed to examine factors affecting the in vitro growth optimi...

biodegradation of phenanthrene (phe) was studied in aqueous culture to demonstrate the potential of the mixed culture in degrading high concentration of phe. the experiments were conducted to monitor biodegradation of phenanthrene for duration of 6 days. biodegradation of phe was successfully achieved in low and middle concentration by the isolated mixed culture. a full factorial central compos...

in this study, we investigated the effects of osmotic process with or without ultrasound on solid gain (sg) and water loss (wl) of cranberries. response surface methodology was used to model and determine the optimum processing conditions for wl and sg during osmotic dehydration of samples. sucrose (40-60%) and salt (0-8%) concentrations, temperature (30-50°c) and frequency of ultrasound (0-130...
