Supplementing exogenous carbon sources is a practical approach to improving shrimp health by manipulating the microbial communities of aquaculture systems. However, little is known about the microbiological processes and mechanisms of these systems. Here, the effects of glucose addition on shrimp growth performance and bacterial communities of the rearing water and the shrimp gut were investigated to address this knowledge gap. The results showed that glucose addition significantly improved the growth and survival of shrimp. Although the α-diversity indices of both bacterioplankton communities and gut microbiota were significantly decreased by adding glucose, both bacterial communities exhibited divergent response patterns to glucose addition. Glucose addition induced a dispersive bacterioplankton community but a more stable gut bacterial community. Bacterial taxa belonging to Ruegeria were significantly enriched by glucose in the guts, especially the operational taxonomic unit 2575 (OTU2575), which showed the highest relative importance to the survival rate and individual weight of shrimp, with the values of 43.8 and 40.6%, respectively. In addition, glucose addition increased the complexity of interspecies interactions within gut bacterial communities and the network nodes from Rhodobacteraceae accounted for higher proportions and linked more with the nodes from other taxa in the glucose addition group than that in control. These findings suggest that glucose addition may provide a more stable gut microbiota for shrimp by increasing the abundance of certain bacterial taxa, such as Ruegeria.

冀豆12是由河北省农林科学院粮油作物研究所育成的高蛋白大豆品种,其蛋白含量高、高产、高抗病。该品种于2001年被农业农村部评选为农作物优异种质,是目前中国推广面积最大的高蛋白品种。为了明确冀豆12的主要表型特征和遗传特性,本研究采用系谱图法结合重测序技术对冀豆12及衍生品种和创新种质进行总结分析,根据多年的生产试验提炼出了冀豆12与其衍生品种和种质的优良特性,并进行重要功能位点在后代品种或品系中的传递情况分析。作为黄淮海地区首个高蛋白品种,冀豆12被作为核心亲本广泛利用。迄今为止已培育出了23个衍生品种,分别在北京、天津、河北、江苏、安徽和湖北等地通过审定并推广应用;并创新出了15个高蛋白特异种质。表型鉴定结果表明,冀豆12的衍生品种在产量相关性状、蛋白含量等品质和花叶病毒抗性上存在较大的变异,生育期、株高的变异范围相对较小。冀豆12与其衍生品种和种质在遗传上主要分为3个亚群。通过热图追踪分析功能位点显示,冀豆12中优异功能位点传递率较高,另有抗蚜虫等不利位点在后代中得到互补改良。衍生品种中蛋白含量变异较大,有两个品种蛋白含量超过冀豆12;冀豆12背景高蛋白含量相关位点个数与衍生品种(或品系)的蛋白含量呈正相关趋势。在利用冀豆12为核心种质进行品种选育的过程中,应注重蛋白含量、花叶病毒抗性等的选择,其次是生育期和株高。同时,在选择亲本时还需要关注蚜虫抗性和耐盐基因的互补。

To separate and concentrate NH4＋ and PO43 from the synthetic wastewater to the concentrated solution through a novel electrochemical reactor with circulated anode and cathode using the difference of the concentration between electrode chamber and middle *** recent years, the research on electrochemical processes have been focused on phosphate and ammonium removal and recovery. Among the wide range of possibilities with regards to electrochemical processes, capacitive deionization （CDI） saves the most energy while at the same time does not have continuity and selectivity. In this study, a new electrochemical reactor with electrolyte cyclic flowing in the electrode chambers was constructed to separate and concentrate phosphate and ammonium continuously and selectively from wastewater, based on the principle of CDI. At the concentration ratio of NaCI solution between the electrode chambers and the middle chamber （r） of 25 to 1, phosphate and ammonium in concentration level of domestic wastewater can be removed and recovered continuously and selectively as struvite. Long-term operation also indicated the ability to continuously repeat the reaction and verified sustained stability. Further, the selective recovery at the certain r could also be available to similar technologies for recovering other kinds of substances.

等离子-物理气相沉积(PS-PVD)具有涂层多结构调控的特性,为高隔热、长寿命热障涂层的制备提供可能,是实现未来高性能航空发动机发展的关键技术之一。PS-PVD柱状结构涂层独特的微观结构使其兼具高隔热和热循环寿命长的双重优势,在航空发动机热障涂层领域有着广阔的应用前景。但PS-PVD柱状结构涂层工艺调控是在大量的实验基础上实现的,缺少相关的理论研究,而且高孔隙率的柱状结构涂层面临的CaO-MgO-Al 2O 3-SiO 2(CMAS)腐蚀失效问题仍然限制着涂层的使用。本文从涂层结构特征入手,阐述了沉积单元相态对涂层结构的影响规律,揭示了柱状结构涂层的气相沉积机理。在此基础上分析了涂层结构的工艺影响,并基于涂层材料在射流内的相态转变,从理论层面阐明了工艺参数调控的本质。此外,分析了PS-PVD柱状结构涂层CMAS腐蚀失效机理,阐述了表面镀铝改性对涂层抗CMAS腐蚀性能的影响机制,并对PS-PVD涂层结构调控和性能提升以及PS-PVD技术在环境障涂层和功能薄膜等领域的应用进行了展望。
