光催化剂负载酰肼基活性炭除甲醛材料的制备

为解决甲醛污染生活环境的问题,利用缩合反应将聚酰肼(PAH)接枝到硝酸改性的活性炭上制备聚酰肼接枝活性炭(ACm-g-PAH),为消除其可能存在的二次污染,负载锰银掺杂纳米二氧化钛可见光光催化剂 (Mn_x/Ag_y-TiO₂)于ACm-g-PAH表面,进一步组装了自净化除甲醛材料锰银掺杂纳米二氧化钛负载聚酰肼接枝活性炭(Mn_x/Ag_y-TiO₂-l-ACm-g-PAH)。借助扫描电子显微镜、红外光谱仪对Mn_x/Ag_y-TiO₂-l-ACm-g-PAH的外观形貌和化学成分进行分析;通过软件Originpro 8.5将其催化甲醛数据与动力学方程进行拟合,并研究了其催化甲醛的动力学规律;对比分析了活化时间、活化温度和N,N-二环己基碳二亚胺(DCC)浓度对Mn_x/Ag_y-TiO₂-l-ACm-g-PAH材料甲醛移除率的影响机制。结果表明:当活化时间为2 h,活化温度为650 ℃,DCC用量为活性炭质量的2%,PAH浓度为11 mmol/L时,所制备材料Mn_x/Ag_y-TiO₂-l-ACm-g-PAH的甲醛移除率为99.6%;甲醛质量浓度在5~28.2 mg/g的范围内,Mn_x/Ag_y-TiO₂-l-ACm-g-PAH的甲醛移除率呈现衰减趋势;经过10次清洗后,材料的自净化能力减少为原来的12%。     

Use of response surface methodology to optimise the hydrolysis of whey protein isolate in a tangential flow filter membrane reactor

Response surface methodology (RSM) was used to investigate the effects of substrate concentration (S), enzyme concentration (E) and initial permeate flow rate, (J_i), on permeate flux behaviour in a 10 kDa nominal molecular weight cut-off (NMWCO) tangential flow filter (TFF) enzyme membrane reactor (EMR) during 3 h hydrolysis of whey protein isolate (WPI) using Protease N Amano (IUB 3.4.24.28, Bacillus subtilis) at pH 7.0 and 45 °C. The average residual permeate flow rate (J_residual), residual enzyme activity (A_residual) and product recovered in permeate designated as apparent sieving (S_apparent) were monitored. The quadratic model regression equations obtained revealed that all the three factors had significant but dissimilar influences on permeate flux behaviour. J_residual, S_apparent and A_residual increased with increasing E, A_residual decreased with increasing J_i and there was substrate inhibition at low E. The optimised factors were S = 4.72% (w/v), E = 0.055% (w/v; hence E/S ≈ 1% w/w) and J_i = 6.91 mL/min (approximately 0.7% reactor volume per minute). The optimised values were 87.24%, 52.37% and 35.08% for J_residual, A_residual and S_apparent, respectively. The actual values for the responses agreed well with the predicted values implying that RSM is suitable for EMR optimisation. Covariance values showed that J_residual and S_apparent increased concomitantly while A_residual decreased with increasing S_apparent and J_residual.     

Pore formation in cured-smoked pork determined with image analysis-effects of tumbling and RN(-) gene

The objective of the present study was to investigate the effects of RN genotype (rn⁺/rn⁺ or RN⁻/rn⁺) and tumbling condition (tumbled or non-tumbled) on the number of undesirable pore formation in cured–smoked loins using image analysis. Even when not significant, RN⁻/rn⁺ loins contained more pores than rn⁺/rn⁺ loins. Tumbling clearly decreased the total number of pores, but increased the mean area per pore. Tumbled rn⁺/rn⁺ loins contained half the number of pores compared with tumbled RN⁻/rn⁺ loins. Even if RN genotype and tumbling influenced the number of pores they did not explain the development of pores in processed meat. The high correlations found when comparing the image analysis results with data from a trained sensory panel and visually scored images indicate that image analysis is a good tool in this type of investigations.     

钠盐与AT毒素对烟苗根生长的影响

为确定不同钠盐对烟草赤星病菌AT毒素毒性的影响,作者采用摩擦接种处理、浇根处理、种子根处理3种生物测定方法确定了以烟草种子根处理法作为烟草赤星病菌的毒性测定方法。用10种化合物分别以5种不同浓度与AT毒素混合接种烟苗,分别以单独接种毒素稀释液与无菌水作对照。根长测定数据经DPS软件统计分析,结果表明单独施用AT毒素明显抑制烟苗根的生长,差异极显著;氢氧化钠、硝酸钠、苯甲酸钠、酒石酸钠均不能改变毒素对根长的影响,碳酸钠(200mg/mL)、酒石酸钾钠(200mg/mL)、四硼酸钠(0.02~0.2mg/mL)、氟化钠(0.2~2mg/mL)、柠檬酸钠(0.2mg/mL-200mg/mL)、钼酸钠(0.02~2mg/mL)对烟草赤星病菌毒素有明显钝化作用,以钼酸钠0.02mg/mL浓度处理效果最好,其次为柠檬酸钠0.2mg/mL处理;钼酸钠20~200mg/mL处理可增加AT毒素的毒性,浓度越大效果越显著。      

Production of Hydrogen Peroxide by Lactobacillus delbrueckii subsp. lactis as Influenced by Media Used for Propagation of Cells

ABSTRACT: Cells of Lactobacillus delbrueckii subsp. lactis I were grown in several media to determine the most suitable medium for production of H₂O₂ during refrigerated storage. H₂O₂ was detected from cells that were resuspended in phosphate buffer containing variable amounts of glucose. Cells grown in MRS broth produced more H₂O₂ during refrigerated storage than those grown in LBS pr PTM. Cells grown in LBS produced more H₂O₂ then those grown in PTM. For both MRS and LBS, cells inoculated in phosphate buffer containing 0% glucose produced significantly more H₂O₂ than those containing 1% or 10% glucose. MRS medium appears to be the best medium for growing cells for the production of H₂O₂.
