    • 摘要: 本试验旨在筛选可用于菜籽粕脱毒的菌株并探讨其发酵菜籽粕的效果.以菜籽粕中主要抗营养因子硫甙为唯一碳源,从发酵青贮与土壤混合液中分离出54株在筛选培养基上生长情况良好的菌株进行分离纯化,以硫甙降解率为因变量进行复筛,初步得到5株硫甙降解率大于30%的菌株.通过菜籽粕固态发酵培养基进行单菌株发酵试验,得到1株硫甙降解率达23.69%的菌株A9,对菌株A9进行形态学观察和16S rDNA序列测定与分析,确定菌株A9为嗜酸乳杆菌,并将其与酿酒酵母、枯草芽孢杆菌进行菜籽粕混菌发酵.结果表明,混菌发酵后的菜籽粕硫甙含量由37.48 μmol/g 降低到25.96 μmol/g,降解率为30.73%;粗蛋白质含量由38.41%提高到45.44%(P<0.05);蛋白质结构发生改变,蛋白质分子质量变小,多肽含量由0.84%提高到2.62%(P<0.05);混菌发酵后的菜籽粕呈黄褐色蓬松状,有浓郁的酸香味,总酸含量由1.01%提高到3.91%(P<0.05).由此可见,混菌发酵后的菜籽粕营养价值与风味得到了有效地改善.%The aim of this study was to screen the bacterial strain for detoxicating rapeseed meal and to investi-gate its effects on fermentation of rapeseed meal. Fifty-four strains with good growth were screened and isolated from mixed liquid with fermented silage and soil through cultivating in medium containing glucosinolate(GS) as a sole carbon source. Five strains were selected based on the degradation ability of GS with degradation rate greater than 30%. According to re-screening in the solid-state fermentation,strain named A9 showed high deg-radation rate(23.69%)of GS. Strain A9 has been identified as Lactobacillus farciminis after morphological observation and 16s rDNA sequence analysis. Rapeseed meal was fermented through mixing Lactobacillus far-ciminis with Bacillus subtilis and Saccharomyces cerevisiate. The results showed that the GS content of rapeseed meal fermented by mixed bacteria decreased from 37.48 to 25.96 μmol/g, and the degradation rate was 30.73%; the crude protein content increased from 38.41% to 45.44%(P<0.05); the protein structure changed, and the molecular weight of protein became smaller, the polypeptide content increased from 0.84%to 2.62%(P<0.05); the rapeseed meal fermented by mixed bacteria was yellow-brown and fluffy with a rich sour aroma, and the total acid content increased from 1.01% to 3.91%(P<0.05). In conclusion, the nutri-tional value and relish of rapeseed meal fermented by mixed bacteria can efficiently improve.

    • 摘要: 以“顺宝”有机肥和“甘油杂1号”甘蓝型油菜为材料,采用田间随机排列方法,并配施有机肥(T1处理)、翻压油菜(T2处理),以单施化肥为对照(CK),研究了种植绿肥对“宁杞5号”枸杞果实产量及品质的影响.结果表明:与CK相比,T1处理枸杞干果年产量显著增加24.1%,夏果和秋果百粒质量分别显著增加4.2%和4.6%;与CK相比,T2处理枸杞干果年产量显著增加19.1%,秋果百粒质量显著增加11.1%.从秋果来看,T1和T2处理干果枸杞多糖、蛋白质、黄酮含量较CK显著增加25.1%、26.4%、16.4%和34.9%、48.5%、24.8%.表明在化肥施用量减半条件下,T1和T2处理均可以提高枸杞果实产量和品质,产量的增加主要通过增加果实大小、百粒质量以及内部干物质的积累来实现.因此,枸杞行间套种油菜作为绿肥,不仅可以减少化肥施用量,还可以提高枸杞产量和品质.

    • 摘要: 为了研究中药对植物蛋白原料混菌固态发酵以及由中药和植物蛋白原料组成的生物发酵饲料对草鱼鱼种生长和非特异性免疫性能的影响,在植物原料中依次添加0.11%、0.33%、0.55%、0.77%、1.1%、3.3%、5.5%、8.8%的复合中药,测定各组总菌数、棉酚去除率、硫甙去除率和乳酸含量。确定最适添加量后,采用随机分组的方法,挑选体重(31±1)g的草鱼600尾,分成5组,K组(阴性对照组)投喂基础饲料,L组(阴性中药组)投喂发酵饲料,M组(阳性中药组)投喂发酵饲料+0.3%中药,N组投喂发酵饲料+0.3%单独发酵的中药,P组投喂发酵饲料+0.3%和发酵基料混合发酵的中药,喂养至60 d,测定各组草鱼鱼种生长及免疫指标。结果表明:中药在0.11%~0.77%的浓度范围内,有利于发酵过程中乳酸含量提高和棉酚、硫甙的降解;在添加量大于3%时,不利于植物原料的微生物发酵;植物蛋白原料中添加0.3%的复合中药共同发酵后,相比较对照组,增重率提高了37.8%,饵料系数降低了17.2%,LSZ、SOD、SBI均有显著提高(P〈0.05),而MDA、GOT、GPT、Cr则显著降低(P〈0.05),说明生物发酵饲料对草鱼鱼种具有明显的促生长及提高非特异性免疫、增强抗病能力的作用;中药和植物原料单独发酵和混合发酵均对草鱼鱼种的生长和非特异性免疫能力的提高具有促进作用(P〈0.05),但两者之间没有显著差异(P〉0.05)。

    • 摘要: Objective]The objective of this study is to explore the duplication and evolution of Brassica rapaMAM which are key genes in the process of glucosinolates synthesis. This study will provide a theoretical basis for futureMAM research.[Method]The synthenic relationship ofMAMgenes amongArabidopsis thaliana,Schrenkiella parvulaandBrassica rapa were analyzed, according toB. rapa datebase BARD, conserved motif ofMAM genes were predicted by online software MEME, the expression of MAMhomologous genes in 93 materials ofBrassica rapa was analyzed by software R, and the phylogenetic tree was constructed by software MEGA 5.05.[Result]The results showed that theMAMhomologous genes were located in three subgenomes ofB. rapa. Amongst sevenMAM genes, five geneswhich are synthenic orthologs toA. thaliana mainly originated from whole genome triplication. The remaining two genes may derive from translocation. Motif analysis result indicated that there were many differences in both ends of protein sequences in BrMAMhomologous genes, compared withAtMAM genes. Expression data showed that the expression level of these homologous genes was variable,Bra021947andBra018524 expressed little in several materials ofB. rapa, the expression ofBra029356could be detected in all materials. In the phylogenetic tree,BrMAMhomologous genes andAtMAM genes were located in different branches, in addition toBra018524.[Conclusion]These results indicated that theB. rapa MAM genes had an independent evolution after the divergence ofB. rapaandA. thaliana.%目的探索硫代葡萄糖甙合成中关键基因-甲基硫代烷烃基苹果酸合成酶(methylthioalkylmalate, MAM)基因在白菜基因组中的进化情况,为研究白菜MAM的功能提供理论指导。方法根据白菜数据库BARD信息分析拟南芥、盐芥和白菜MAM的共线性关系,利用MEME在线软件预测MAM序列的高度保守基序(motif),通过R软件分析93份白菜材料MAM的表达模式,并利用MEGA5.05软件构建MAM的系统进化树。结果白菜的3个亚基因组均保留着MAM的同源基因。其中与拟南芥具有共线性的5个同源基因可能源自基因组古三倍化复制,其它两个同源基因可能是由转座扩增产生的;基序分析结果表明,与拟南芥的MAM相比,白菜的MAM同源基因存在基序的缺失,并且大多发生在序列的两端;在93份白菜材料中,白菜MAM同源基因之间的表达量有很大差异,Bra021947与Bra018524只在少数材料中存在极低的表达,并且Bra029356的表达量低于可检测水平;进化树分析发现,除Bra018524外,其他的白菜MAM同源基因与拟南芥的MAM聚集在不同的分支上。结论白菜的MAM可能在拟南芥和白菜物种分化之后独立起源并进化出不同的功能。

    • 摘要: 烹调时,人们最担心营养受损的莫过于蔬菜了。蔬菜可以炒,可以煮,可以蒸,可以凉拌……到底哪种方法更有利于保存其中的营养,有利于多吃蔬菜以及预防各种疾病呢?炒营养素损失较少烧热油,炝锅,加入蔬菜翻炒,熟了立刻盛出。优点是各种蔬菜都可使用,炒后蔬菜体积大幅度缩小,能帮助一天吃到一斤蔬菜,营养素损失率相对较低。缺点是需要较多的油才能达到较好的口感,对健康不利。如果烹调时没有控制好油温,油脂过热会产生致癌物。
