Cross-flow microfiltration of rough non-alcoholic beer and diluted Malt Extract with tubular ceramic membranes: Investigation of fouling mechanisms
Journal of Membrane Science, 2010Co-Authors: Mehdi Yazdanshenas, Mohammad Soltanieh, Seyyed Alireza Tabatabaei Nejad, Luc FillaudeauAbstract:Abstract The clarification of rough non-alcoholic beer (RNAB) and diluted Malt Extract (DME) was investigated in a pilot plant consisting of a tubular ceramic membrane with nominal pore diameter of 0.45 μm. The results of the primary experiments show that the concentration of suspended particles in the RNAB (∼0.05 kg/m 3 ) and DME (∼0.2 kg/m 3 ) correlates proportionally to turbidity (in NTU) with the factor of 4.45 × 10 −4 (kg m −3 NTU −1 ). During cross-flow microfiltration (CFMF), flux declined drastically with time due to fouling mechanisms and propensity. According to the characterizing curve of log( d 2 t / dV 2 ) versus log( dt / dV ), fouling is initiated by penetration of aggregates through the membrane surface, followed by blocking of the pores for the first 15 min of operation. Cake formation mechanism controls the fouling phenomenon above 20th minute of operation and continues until achieving a quasi-steady-state flux. The specific cake resistance of DME particles was found to change from 6.7 × 10 14 to 36.9 × 10 14 m/kg for the transmembrane pressures (TMP) of 52–207 kPa and the compressibility factor of the cake was evaluated to be 1.027, indicating that the cake layer is highly compressible. This finding is corroborated with previous works in the literature. This explanation for the mechanisms was further verified using scanning electron microscopy (SEM), which showed a distinct cake layer with thickness of about 30–40 μm on the membrane surface and no constriction of pores. The contributions of each, reversible and irreversible fouling were evaluated by comparison of hydraulic resistances after water rinsing, water backwashing and chemical cleaning of the fouled membrane. The reversible fouling including gel and stationary cake layers contributed to more than 95% of the hydraulic resistance and the remainder was attributed to irreversible fouling. The in-pore fouling contributed to 5% of irreversible fouling resistance and 0.2% of total resistance. These observations confirm that microfiltration of RNAB is controlled by formation of cake layer on the surface of the membrane and therefore hydrodynamic techniques may play a significant role in improving the performance of the operation.

fructification of antrodia cinnamomea was strain dependent in Malt Extract media and involved specific gene expression
Journal of Agricultural and Food Chemistry, 2010Co-Authors: Rueimei Yang, Tuntschu Chang, Jyhching ChouAbstract:Antrodia cinnamomea is an expensive medicinal fungus that grows only inside the rotten trunk of Cinnamomum kanehirae. In vitro culture of A. cinnamomea fruiting body is difficult and, therefore, of value for further investigation. To study whether the fructification of A. cinnamomea is strain dependent in artificial media, we grew four different A. cinnamomea strains on Malt Extract agar (MEA) media. The standard MEA and a series of dilution of the MEA nutrient components were made to culture A. cinnamomea. The formation of fruiting body was determined by visual and microscopic observation on A. cinnamomea’s porous morphogenesis and HPLC analysis. All A. cinnamomea strains cultured grew best in 50% MEA, but carried different capabilities of fructification. In addition, we studied four antioxidation- or senescence-related genes, including a cytochrome P450, a glutathione-S-transferase, a peroxiredoxin, and a manganese superoxide dismutase. We found both cytochrome P450 and glutathione-S-transferase were ex...

Mapping a major QTL for Malt Extract of barley from a cross between TX9425 × Naso Nijo.
TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2015Co-Authors: Junmei Wang, Jianming Yang, Qisen Zhang, Jinghuan Zhu, Qiaojun Jia, Wei Hua, Yi Shang, Meixue ZhouAbstract:Improving Malting quality traits is one of the major breeding objectives for barley breeding programmes. Among different quality traits, Malt Extract is one of the most important, determining the yield of beer production. The use of molecular markers linked to loci affecting the quality traits can greatly improve selection efficiency. However, the discovery of closely linked markers relies on not only the availability of the loci, but the accuracy of phenotyping. In this experiment, 188 doubled-haploid lines derived from the cross between a Japanese Malting barley and a Chinese feed barley were grown in four different environments (two sites × 2 years). Different quality traits were determined and used to map QTL for these traits. Several QTLs were identified for different quality traits. One major QTL-controlling Malt Extract was identified on 2H and determined 48 % of phenotypic variation with the closest marker of GBM1121. This QTL was consistently expressed in all four environments and is of a high value for marker-assisted selection in Malting barley breeding.
