Abstract:对不同菌株、不同培养基和培养时间对金针菇菌丝体产量和金针菇多糖产量的影响进行了研究,并对金针菇胞外多糖进行了紫外和红外分析。结果表明,金针菇12号菌株在液体培养基中培养10~11 d时金针菇菌丝多糖含量和金针菇菌丝体产量最高,金针菇胞外多糖产量较高。紫外和红外分析结果表明,本研究所分离的金针菇胞外多糖为一种含β-型吡喃糖苷键的纯多糖。采用不同的培养基对金针菇胞外多糖的主体结构影响不明显,均有相似的多糖特征峰和β-型吡喃糖苷键吸收峰。但采用玉米、黄豆等配制的培养基更有利于工业化生产金针菇多糖。

Abstract:探讨了一系列有关菇床的制备、栽培料的处理和发酵等提高平菇产量的栽培措施。为了提高锯木屑的利用率,在制备菇床时引进了发酵技术;为了解决生长中一些基础问题,改进了培养基质的处理方法。同时也评估了聚乙烯薄膜钻孔覆盖技术对两种平菇(Pleurotus ostreatus和P.sajor-caju)产量和品质的影响。在平菇菇床制备的过程中,为避免其它真菌菌丝的污染,使用了发酵后的锯木屑法。结果表明,所用的3种添加物中,稻糠是促使培养基质升温效率最高的添加物,可以升高70℃。应用发酵锯木屑添加稻糠生产的菌丝的活力和密度大大高于非发酵锯木屑在接种后30d内对木霉无能为力。研究了堆料(发酵)对平菇培养基物效率的提高能力。在白杨树锯木屑和冬蘑菇的栽培废料中加入10的米糠后,在20~28℃下室外堆放12d。在发酵锯木屑钵中发酵的持续时间缩短3d。平菇在发酵基质中生长可以加快子实体原基的形成。用棉籽壳和发酵的白杨锯木屑混合可以获得最高的产量(742g),而对照只有663g。另外,用白杨锯木屑与冬蘑菇培养废料混合可以最有效提高发酵效率。在棉籽壳中添加发酵的锯木屑和可循环的农副产品可以促进培养基质发酵和子实体形成。许多问题,凿孔聚乙烯薄膜覆盖技术被用来栽培Pleurotus ostreatus和Pleurotus sajor-caju.菇水覆以打孔的、透明的、黑色的塑料膜(0.03mm厚,孔直径10cm,孔间距10cm以保证25孔/m^2)。菌种自孔接入菇床表面。此项技术因蘑菇成束形成而使采摘时效率更高,P.ostreatus的产量每平方米增加5.7%到10.8kg。聚乙烯薄膜覆盖的菇床每束蘑菇的平均重量283g(33子实体),而传统的栽培方法为117g(15子实体)。P.sajor-caju可以快速在基质上生长和定殖,并在孔口周围成束长出子实体。P.sajor-caju栽培系统的总产量为8kg/m^2,薄膜覆盖栽培平均每束菇的重量为225g(79个子实体,而传统的方法栽培的平均子实体产量为2.5g。由于菇床平坦,有利于快速采摘,降低劳动力达52%(P.ostreatus)或64%(P.sajor-caju)。在薄膜下面,平菇的菌丝保持健白色,健康状态,而传统的栽培经过一轮的采摘后,菌丝变黄。用薄膜覆盖技术很少出现菇体不能发育成熟的现象。因此这种建立在提高栽培料组合和发酵基础上的平菇栽培新方法值得推荐。

Abstract:在韩国的平菇(Pleurotus ostreatus )商品化种植基地发现了真菌病毒的自然流行为害的现象。这些病害经常伴随着一些球形病毒粒体的出现。采用Tris-EDTA缓冲液提取,PEG-NaCl沉淀和CsCl梯度离心,依据不同的比重,获得了3种病毒粒体,其中1种病毒粒体直径为27nm,另外2种的粒体为27nm,并推定这些病毒共同感染栽培的平菇。其中1种27nm的球形病毒,其比重较34nm的病毒大,称为平菇球形病毒(OMSV),该病毒含有2条大小分别为6.00kb和1.25kb的ssRNA片段。直径为34nm的病毒有两种比重小的粒体,其中1种常与OMSV共感染平菇,称为平菇等面体病毒-I(oystermushroom isometric virus-I ,OMIV-1),该病毒含有12条dsRNA片段,它们的大小分别是2.65,2.45,2.40,2.20,2.15,2.10,2.05,2.00,1.90,1.80,1.00和O.80kb。另外一种称之为平菇等面体病毒-II(oyster mushroom isometric virus-II, OMIV-II),.含有3条dsRNA片段,大小分别是2.25,2.15和2.05kb。经聚丙烯酰胺凝胶(12%)电泳、考马斯量兰染色表明OMSV,OMIV-I和OMIV-II病毒粒体的外壳蛋白的分子量大小分别是29kDa、71kDa和62kDa。这些结果表明在平菇中至少存在3种不同的ssRNA和dsRNA病毒。

Abstract:自韩国平菇生产地分离到26株木霉(Trichoderma),基于培养特性和菌落形态,这些菌株分为4组,鉴定为Trichoderma sp.K1、Trichoderma sp.K2、T.harizianum,和T.atroviride,其中优势种为Trichoderma sp.K2,其次是Trichoderma sp.K1和T.atroviride。K1和K2不仅在形态上与其它的组有区别,而且相互在生长温度(35℃),菌落形态,分生孢子的形态,分生孢子小梗及其分枝类型,分生孢子的形态等方面有显著差异。对这些菌的ITS、EF-1(和RPB2的序列比较显示出这2个待鉴定的种(K1和K2)不仅与早期报道的木霉种有差异,而且相互间也显著不同。同时发现,EF-1(和RPB2序列比ITS序列在木霉的系统分类上更加客观可靠。基于以上研究结果,我们认为K1和K2是木霉属中的新种,即将给予它们新的名称。

Abstract:天然产物紫杉醇是一种重要的抗癌药。其天然来源的匮乏和缺少商业上可行的化学全合成促进了对紫杉醇生物来源的深入研究。紫杉醇的生物合成是一个复杂的多步过程,主要包括四环骨架的构建和加入各种羟基和酰基基团,其中羟基的加入由细胞色素P450氧化酶催化。我们从中国红豆杉愈伤组织细胞mRNA构建的cDNA文库中克隆得到几个P450 cDNA片段。其中一个长1494bp的cDNA片段,编码497个氨基酸,推断蛋白分子量为56470 Da,等电点为9.42。序列比较显示,这个推断蛋白包含多个细胞色素P450氧化酶的保守区,具有典型的细胞色素P450氧化酶的特征,进一步的比较发现其与已鉴定的东北红豆杉紫杉烷-10β-羟化酶有92%的同源性。将这个cDNA片段连接在质粒pYeDP60上构建表达载体,导入相应的酵母表达菌株WHT和WVS进行表达,获得相应大小的蛋白表达条带,功能鉴定的工作正在进行中。
