The invention relates to a new strain producing taxol and a taxol preparation method. The taxol is a diterpenoid alkaloid drug which is extracted from taxaceae plants and has a plurality of anti-tumor effects. Taxus, also known as yew, is a prehistoric plant with a history of 0.2 billion years and is a rare plant species with low growing speed; the biological characteristics of the taxus have high demand on the ecological environment; the natural renewal ability is poor, so the amount of the species is very limited, belonging to an endangered protection plant with limited resource, thus, scientists at home and abroad actively research and develop new taxol sources. The new strain for producing the taxol of the invention is the strain which is first separated from the bark of T.cuspidate Sieb.
产紫杉醇的新菌种及其选育和制备紫杉醇的方法,紫杉醇是从红豆杉属植物中提取出来的具有多种抗肿瘤疗效的二萜生物碱类药物,由于红豆杉,又名紫杉,是两亿年前的史前植物,是珍稀树种,生长速度缓慢,并且其生物学特性对生态环境要求较高,天然更新能力差,所以种群数量极为有限,属濒危保护植物,资源十分有限,因此,国内外学者都在积极地研究开发紫杉醇的新药源,本发明产紫杉醇的新菌种,所述的新菌种为从东北红豆杉T.cuspidate Sieb。

Thereinto, drip irrigation is divided into three treatments of different ration. Tectorial and untectorial treatment are adopted to semifixation spray irrigation. At the same time, seepage-preventing trial is done. By study of one growth season, it shows that the indexes, Comparing with flood irrigation, water-saving technique has the effect of increasing production and harvest, economizing water, energy sources and field, saving work, time and power. It has best significance difference among unit yield of using different irrigation ways. The highest yield is in irrigation treatment of 80% field moisture capacity, it is secondary in seepage-preventing ditch irrigation treatment and is the lowest in spray irrigation treatment. Drip irrigation increase yield 4.0%~25.9%,Seepage-preventing ditch irrigation increase yield 17.5%, and spray irrigation decrease yield 22.4~37.8% comparing with flood irrigation. The effect to yield is obvious in drip irrigation treatment of different irrigation ration.
不同灌溉方式间单位产量存在显著差异,80%田间持水量灌溉处理产量最高,防渗渠畦灌次之,喷灌的产量最低;与土渠漫灌单位产量相比,滴灌增产4.0%~25.9%;防渗渠畦灌增产17.5%;喷灌产量下降22.4%~37.8%;滴灌试验中不同灌溉处理对产量的影响显著,随着灌溉定额的减少,产量随之下降,主要原因是60%田间持水量的灌溉处理限制了棉株的生长发育,降低了产量;不同灌溉方式的灌溉定额与绿洲内土渠漫灌平均灌溉定额相比,滴灌节水47.7%~54.4%,防渗渠畦灌节水38.56%,喷灌节水58.2%;滴灌、喷灌及防渗渠畦灌与土渠漫灌相比分别省工16.2%、25.1%和3.6%;滴灌和喷灌较防渗渠畦和土渠漫灌节地约5%~7%;从净收益来看,防渗渠畦灌较土渠漫灌经济效益提高了34.2%,滴灌提高了9.8%~48.2%,喷灌则下降了23.8%和44.7%;而且采用不同灌溉方式种植棉花,对于成铃率、衣指、衣分、纤维长度、产量等指标,滴灌要优于喷灌和防渗渠畦灌;而成铃数、种子数、铃重、籽指等指标,滴灌、喷灌均小于防渗渠畦灌。

To determine the regulating role of mtlR in transcription of mannitol PTS operon in V.cholerae,and whether it plays a role in the ferment difference of the toxigenic and non-toxigenic strains,the mtlR deletion mutants from the mannitol rapid-ferment strain(non-toxigenic strain) and slow-ferment strain were constructed.Comparisons of the growth in M9 containing 0.2% mannitol as the sole carbon source and pH change in mannitol fermentation media of these wild strains and their mutants,indicated that mtlR is a repressor.Its repression in mtlCBA transcription was further verified with the analyses of quantitative reverse-transcriptional PCR.
