Coconut(Cocos nucifera L.)is an important economic crop in tropical countries.However,the lack of a complete reference genome and the limitations of usable DNA markers hinder genomic studies and the molecular breeding of coconut.Here,we present the results of simple sequence repeat(SSR)mining from a high-throughput genotyping-bysequencing(GBS)study of a collection of 38 coconut accessions.A total of 22,748 SSRs with di-,tri-,tetra-,penta-and hexanucleotide repeats of five or more were identified,2451 of which were defined as polymorphic loci based on locus clustering in 38 coconut accessions,and 315 loci were suitable for the development of SSR markers.One hundred loci were selected,and primer pairs for each SSR locus were designed and validated in 40 coconut accessions.The analysis of 74 polymorphic markers identified between 2 and 9 alleles per locus,with an average of 3.01 alleles.The assessment of the genetic diversity and genetic relationships among the 40 coconut varieties based on the analysis of population structure,principal coordinate analysis(PCoA),and phylogenetic tree analysis using the 74 polymorphic SSR markers revealed three main groups of coconuts in Thailand.The identified SSR loci and SSR markers developed in this study will be useful for the study of coconut diversity and molecular breeding.The SSR mining approach used in this study could be applied to other plant species with a complex genome regardless of the availability of reference genome.

Superhydrophobic bagasse paper was successfully engineered by facile spray coating with a zeolitic imidazolate framework composite modified by 3,3,3-trifluoropropyltrimethoxysilane(FAS)and used as a filter membrane with special wettability for oil/water separation.Surface characteristics such as surface morphology,surface moieties,roughness,and wettability were observed.The addition of FAS decreased the apparent surface energy between solid surfaces and liquids with a polar contribution of surface free energy as low as 0 mN m−1.The formation of the FAS layer was confirmed by transmission electron microscopy and X-ray photoelectron spectroscopy core-level spectra.Three-dimensional surface topography revealed an increase in the spray coating cycle that enhanced the hydrophobicity of the coated paper.The results confirmed that not only microstructures but also the presence of functional groups with low surface energy(such as FAS)can promote surface hydrophobicity.The spray-coated paper with FAS/ZIF in the presence of a small amount of nanocellulose provided a superhydrophobic surface after the first spray cycle.The separation efficiency was up to 85%and was slightly affected by oil viscosity.Moreover,this can be used as a filter membrane for water-in-oil emulsions.In the present work,simple spray-coated paper is a promising candidate material for gravity-driven oil/water separation and water repellent coating.

In this work,to efficiently utilize waste fruit and low-rank coal for the hydrogen(H_(2))-rich syngas production,steam co-gasification of banana peel(BP)and brown coal(BC)was studied in a fixed-bed reactor.The results showed that the gasification rate of BC was highly enhanced after mixing it with BP and the obvious synergistic effect was observed in all investigated three mixing weight ratios(i.e.,1:1,1:4,4:1),resulting in a higher carbon conversion as well as a H_(2)-rich gas production yield for the co-gasification.However,the extent of promotion by synergistic effect was affected by the reaction temperature,mixing ratio,and steam amount.It was found that the high potassium(K)species content in the BP provided the catalytic effect not only on water-gas shift reaction but also on tar reforming/cracking,thereby enhancing the gasification of BC.In addition,it is confirmed that steam should be an important factor to promote the synergistic effect and H_(2)-rich gas production.

In this work,the etherification of glycerol with n-butanol catalyzed by sulfonic acid functionalized on KIT-6 mesoporous silica(SO_(3)H-KIT-6)was investigated for the production of valuable fuel additives.The SO_(3)H-KIT-6 catalyst was synthesized by co-condensation with different molar ratios of tetraethoxysilane and 3-mercaptopropyl(methyl)di-methoxy silane.The etherification reaction was systematically examined to determine the optimal reaction temperature,reaction time,catalyst loading,and glycerol to n-butanol ratio under autogenous pressure.The maximum glycerol conversion and di-glyceryl n-butyl ether(di-GNBE)selectivity were 59.09 and 51.50%,respectively,when the SO_(3)H-KIT-6 catalyst with the highest acidity was applied.Interestingly,the presence of a methyl group on the catalyst surface prevented glycerol adsorption during the reaction process,leading to the inhibition of undesired product formation.The SO_(3)H-KIT-6 catalyst could be reused up to three times,with only a 13%decrease in glycerol conversion being found.Moreover,the superior performance of the SO_(3)H-KIT-6 catalyst for di-GNBE production was also demonstrated compared with conventional solid acid catalysts including HZSM-5,H-beta zeolite,Amberlyst-35,and Amberlyst-36.

文章从敬畏情绪原型理论及情绪评价理论角度出发,探索游客在我国山岳型旅游目的地自然环境与宗教氛围中如何产生敬畏情绪体验,敬畏情绪又如何影响游客满意度与游客忠诚。文章通过对峨眉山风景区游客进行问卷调查,实证检验了以"环境评价-情绪体验-满意度-忠诚"为路径的概念模型。其中,由自然环境和宗教氛围组成的环境因素能够诱发游客的敬畏情绪,敬畏情绪作为中介变量在自然环境对游客满意度的影响路径中起部分中介作用,在宗教氛围对游客满意度的影响路径中起完全中介作用,敬畏情绪体验又通过游客满意度的中介,进一步正向影响游客忠诚。文章合理解释了情绪评价理论视角下环境对游客满意度和忠诚的影响,研究结果为山岳型风景区如何利用自然资源和宗教资源激发游客敬畏情绪、提高游客满意度、提升景区美誉度、培养忠诚游客提供了理论借鉴。

顾客心理所有权指消费者将企业、品牌、产品、服务等目标物或其一部分视为"自己的"的一种心理状态,强调顾客对与消费有关的目标物的拥有感。顾客心理所有权超越了实际所有权,被认为是致使禀赋效应发生的根本原因,会影响顾客的产品价值评价与购买意愿;它同时代表了顾客关系发展的终极形式,连接着稳定性最强和盈利性最高的顾客,对顾客忠诚和顾客公民行为都有重要影响。本文对国内外有关顾客心理所有权的文献进行了梳理,从顾客心理所有权的概念、起源和测量、影响因素、影响效应等方面对现有研究成果进行了系统回顾和述评,并对顾客心理所有权在顾客定制、B2B顾客关系、本土品牌、广告等研究领域的未来应用方向进行了展望。

Journal of Life Sciences 2011年第11期5卷 960-966页

作者： Waranya Suwannasing samart Moonamart Pakawadee Kaewkannetra Department of Biotechnology Graduate School of Khon Kaen University Khon Kaen 40002 Thailand Fermentation Research Center for Value Added Agricultural Products （FerVAAP） Faculty of Technology Khon Kaen University Khon Kaen 40002 Thailand Department of Biotechnology Faculty of Technology Khon Kaen University Khon Kaen 40002 Thailand

In this work, sugar cane juice was fermented to produce polyhydroxyalkanoates (PHAs) by Alcaligenes latus TISTR 1403 and A. eutrophus TISTR 1095. The juice was characterized and composed of total sugars 105.5 g·L-1 (sucrose 36.6 g·L-1, fructose 26.0 g·L-1, glucose 21.8 g·L-1 and other sugars 21.1 g·L-1). Each inoculums (10%, v/v) was separately cultivated in the medium containing 20 g·L-1 total sugars under condition (30oC, 200 rpm, pH 6.5-7). It was found that the A. eutrophus can be grown better than the A. latus. Only the A. eutrophus was further cultured under different total sugar concentrations (20, 30, 40 and 50 g·L-1). The optimal contents of total sugar, dry cell mass (DCM) and maximum PHAs were obtained at 50 g·L-1, 6.013 g·L-1 and 1.84 g·L-1, respectively after 60 h fermentation which were converted to biomass yield (Yx/s), product yield (Yp/s), specific product yield (Yp/x) and productivity of 0.163, 0.05, 0.306 and 0.031 g·L-1h-1. Large scale of PHAs production was conducted in 5 L fermentor using the optimal condition obtained under 30% dissolved oxygen. The DCM and the maximum PHAs were 5.881 g·L-1and 1.281 g·L-1 which were calculated to values of Yx/s, Yp/s, Yp/x and productivity at 0.19, 0.04, 0.218 and 0.021 g·L-1h-1, respectively.
