The results showed that wild E. gelatinae had greater frond,with more and longer branches. The main compositions of wild and farmed E. gelatinae were carbohydrates composed of dietary fiber and soluble sugars. The wild E. gelatinae had higher soluble sugar content than farmed E. gelatinae,while farmed E. gelatinae had higher dietary fiber and carrageenan yield.Both of wild and farmed E. gelatinae had advantages and disadvantages,and we could choose the best raw materials according to the actual application.展开更多
为了评价琼枝麒麟菜多糖(EGP)包括粗提物(CEGP)及大于500 k Da多糖组分(LEGP)抗呼吸道相关病毒活性。采用Reed-muench法计算流感病毒H1N1、H3N2和H5N3,柯萨奇病毒CVB3及呼吸道合胞病毒RSV-long株滴度;采用观察细胞病变效应(CPE)法,确定C...为了评价琼枝麒麟菜多糖(EGP)包括粗提物(CEGP)及大于500 k Da多糖组分(LEGP)抗呼吸道相关病毒活性。采用Reed-muench法计算流感病毒H1N1、H3N2和H5N3,柯萨奇病毒CVB3及呼吸道合胞病毒RSV-long株滴度;采用观察细胞病变效应(CPE)法,确定CEGP和LEGP对犬肾细胞(MDCK),人宫颈癌细胞(He La)和人喉癌上皮细胞(HEp-2)的最大无毒浓度;通过细胞病变观察法(CPE)及四甲基偶氮唑盐微量酶反应比色法(MTT法)测定CEGP和LEGP抑制各病毒产生细胞病变的作用。结果表明:CEGP和LEGP对5种常见的呼吸道病毒H1N1、H3N2和H5N3,CVB3和RSV都有抑制作用,CVB3和RSV对CEGP和LEGP更敏感;CEGP和LEGP有抗多种呼吸道病毒作用,为抗呼吸道病毒新药的研发提供理论依据。展开更多
分析了水泥框网片夹苗养殖(简称夹苗养殖)和鱼排浮筏式挂养养殖(简称挂养养殖)两种模式养殖琼枝麒麟菜(Eucheuma gelatinae)的经济效益和生态效益。通过对比几种大型海藻对海水氮(N)、磷(P)无机盐和重金属吸收去除能力。结果表明,琼枝...分析了水泥框网片夹苗养殖(简称夹苗养殖)和鱼排浮筏式挂养养殖(简称挂养养殖)两种模式养殖琼枝麒麟菜(Eucheuma gelatinae)的经济效益和生态效益。通过对比几种大型海藻对海水氮(N)、磷(P)无机盐和重金属吸收去除能力。结果表明,琼枝对无机磷的吸收能力优于其他藻类,对钙(Ca)、铁(Fe)元素的吸附效果显著优于海带和紫菜;以这两种养殖模式每养殖1 hm2琼枝,采用水泥框网片夹苗养殖模式可以去除海水中1.6 t N和7.7 t P,采用挂养养殖琼枝可去除海水1.9 t N和9.2 t P;而夹苗养殖技术具有易于推广的特点,年产量约1 500 kg;挂养养殖模式易受到养殖区域的限制,适用于苗种生产,年产量约1 800 kg。综合来看,两种养殖模式均有水质优化效果显著、经济效益高等特点;琼枝麒麟菜可以作为理想型的热带海域净化水质的经济型大型海藻进行推广。展开更多
