    • The present invention relates to a method of obtaining different biologically pure cultures of bacteria isolated from different species of Taxus such as Taxus canadensis. T. brevifolia, T. baccata, T. cuspidata, and T. hunnewelliana, wherein the bacteria produce in vitro taxanes and paclitaxel, and wherein the bacteria are of the genus Sphingomonas, Bacillus, Pantoea or Curtobacterium. Also, the present invention relates to a method of a bacterial mass production of at least one taxane or paclitaxel. There is also disclosed a novel bacterial taxane. The present invention also relates to the use of different biologically pure cultures of bacteria isolated from different species of Taxus, wherein the bacteria are able to biotransform pro-taxanes. There is also provided a process for improving taxanes and paclitaxel production of taxanes and paclitaxel producing bacteria which include culturing bacteria in the presence of a mutagenic agent for a period a time sufficient to allow mutagenesis. There is disclosed two new mutated bacteria which have an increased yield of pro-taxane biotransformation.
    • 本发明涉及从不同种类的红豆杉(Taxus canadensis)分离得到的细菌的不同生物纯培养物的方法。 T. brevifolia,T.cuspidata和T. hunnewelliana,其中细菌在体外产生紫杉烷和紫杉醇,其中细菌是鞘氨醇单胞菌属,芽孢杆菌属,泛菌属或曲霉属。 另外,本发明涉及细菌大量生产至少一种紫杉烷或紫杉醇的方法。 还公开了一种新型细菌紫杉烷。 本发明还涉及从不同种类的红豆杉分离的细菌的不同生物纯培养物的用途,其中细菌能够生物转化前紫杉烷。 还提供了一种改善紫杉烷类和紫杉醇生产细菌的紫杉烷类和紫杉醇生产的方法,其包括在致突变剂存在下培养细菌足以允许诱变的时间。 已经公开了两种新的突变细菌,其具有增加的前紫杉烷生物转化产率。
