本申請是申請?zhí)枮?00980126943.6的中國專利申請的分案申請,原申請是申請日為2009年5月20日的國際申請pct/ep2009/056181的中國國家階段申請。本發(fā)明涉及生產(chǎn)二羧酸的方法。本發(fā)明特別涉及通過酵母的發(fā)酵來生產(chǎn)二羧酸。
背景技術(shù)
:二羧酸(例如延胡索酸和琥珀酸)是重要的化合物,其在食品工業(yè)中用于食物制備和防腐,在醫(yī)藥工業(yè)中用于配制藥物制品,以及用于其他工業(yè)用途,例如(生物)聚合物的單體。為了滿足對二羧酸的日益增加的需要,正在開發(fā)更高效和更具成本效益的生產(chǎn)方法。傳統(tǒng)上通過發(fā)酵能夠生產(chǎn)大量二羧酸的細(xì)菌來制造二羧酸。這例如描述于us5,573,931中,其中描述了通過使用細(xì)菌菌株生產(chǎn)高濃度的琥珀酸的方法。然而,與用細(xì)菌生產(chǎn)二羧酸的用途相關(guān)的一個(gè)主要的缺點(diǎn)是二羧酸鹽的形成。如果使用細(xì)菌,則發(fā)酵期間的ph需要被維持在ph6-7的范圍內(nèi),這高于所有二羧酸的pka值。因此,大部分酸將以其鹽的形式被生產(chǎn),這些鹽必須被轉(zhuǎn)化成酸。在大規(guī)模生產(chǎn)方法中這不實(shí)用不高效,并且提高生產(chǎn)成本。此外,并非細(xì)菌的微生物也已被用于生產(chǎn)有機(jī)酸。ep0424384公開了在含有碳酸鈣的培養(yǎng)基中通過rhizopus生產(chǎn)有機(jī)酸的需氧方法。ep1183385公開了經(jīng)遺傳操縱的酵母細(xì)胞,所述酵母細(xì)胞具有crabtree陰性表型并且含有用于生產(chǎn)乳酸的外源核酸分子。技術(shù)實(shí)現(xiàn)要素:本發(fā)明涉及用于生產(chǎn)二羧酸的方法。所述方法包括在低于二羧酸pka的ph值下,在存在含碳水化合物的底物和少量氧時(shí)發(fā)酵酵母。本發(fā)明的方法提供了二羧酸產(chǎn)物的高產(chǎn)率,允許更簡單的下游加工,并且比現(xiàn)有方法更具成本效益,現(xiàn)有方法中生產(chǎn)的是鹽,其必須隨后被轉(zhuǎn)化成酸。因?yàn)槎人峋哂卸嘤谝粋€(gè)的pka值,所以ph應(yīng)當(dāng)?shù)陀诙人岬淖畹蚿ka。對大部分酸而言,ph應(yīng)典型地在ph1.0到ph5.5的范圍內(nèi),優(yōu)選地在ph2.0和ph4.0之間。在一個(gè)實(shí)施方案中,在3.0的ph值下生產(chǎn)琥珀酸。另一優(yōu)點(diǎn)是由于ph低,所以污染的風(fēng)險(xiǎn)被降低。酸生產(chǎn)階段之前優(yōu)選是針對最優(yōu)生物質(zhì)生產(chǎn)的生物質(zhì)形成階段。在生物質(zhì)形成階段中,ph在ph2到ph7的范圍內(nèi)。優(yōu)選地,ph在ph3到ph6的范圍內(nèi),更優(yōu)選地,ph在ph4到ph5的范圍內(nèi)。根據(jù)本發(fā)明的方法更具成本效益,并可導(dǎo)致低30%的成本價(jià)格。原因之一是滴定劑成本被顯著降低。本發(fā)明的方法可被用于生產(chǎn)任何二羧酸。合適的例子包括己二酸、延胡索酸、衣康酸(itaconicacid)、琥珀酸、蘋果酸、草酸。優(yōu)選地,二羧酸是琥珀酸、延胡索酸或蘋果酸。在本發(fā)明方法中使用的酵母可以是任何合適的酵母。酵母的合適例子包括saccharomyces、schizosaccharomyces、kluyveromyces、candida、pichia和yarrowia,例如saccharomycescerevisiae、schizosaccharomycespombe、kluyvermoceslactis、candidasonorensis、pichiastipidis和yarrowialipolytica的物種。在一個(gè)實(shí)施方案中,本發(fā)明方法中使用的真核微生物是saccharomycescerevisiae——一種廣泛使用的工業(yè)上感興趣的微生物。在一個(gè)優(yōu)選的實(shí)施方案中,根據(jù)本發(fā)明的酵母是經(jīng)遺傳修飾的酵母。在本文中使用時(shí),在根據(jù)本發(fā)明的方法中經(jīng)遺傳修飾的酵母被定義為下述酵母細(xì)胞,其含有所述酵母細(xì)胞中天然不存在的核苷酸序列或多肽,或者經(jīng)所述酵母細(xì)胞中天然不存在的核苷酸序列或多肽轉(zhuǎn)化或遺傳修飾過,或者其含有內(nèi)源核酸序列的額外的一個(gè)或多個(gè)拷貝。野生型酵母細(xì)胞在本文中被定義為重組細(xì)胞的親本細(xì)胞。優(yōu)選地,根據(jù)本發(fā)明的方法中的酵母是經(jīng)遺傳修飾的酵母,其包含編碼選自下組的異源酶的核苷酸序列,所述組由磷酸烯醇式丙酮酸羧激酶、延胡索酸還原酶和延胡索酸酶組成。異源酶的優(yōu)選的實(shí)施方案如下文定義。當(dāng)用于指出給定的(重組)核酸或多肽分子與給定的宿主生物或宿主細(xì)胞之間的關(guān)系時(shí),術(shù)語“同源的”應(yīng)當(dāng)被理解為表示該核酸或多肽分子天然地由相同物種、優(yōu)選地相同品種或株系的宿主細(xì)胞或生物生產(chǎn)。在關(guān)于核酸(dna或rna)或蛋白質(zhì)的方面,使用術(shù)語“異源的”表示下述核酸或蛋白質(zhì),其不作為其存在的生物、細(xì)胞、基因組或dna或rna序列的部分天然存在,或其被發(fā)現(xiàn)于與其天然被發(fā)現(xiàn)的細(xì)胞或基因組或dna或rna序列中的位點(diǎn)不同的細(xì)胞或位點(diǎn)。異源核酸或蛋白質(zhì)對其被引入的細(xì)胞而言不是內(nèi)源的,而是得自另一細(xì)胞或是以合成方式或重組方式生產(chǎn)的。優(yōu)選地,經(jīng)遺傳修飾的酵母包含編碼磷酸烯醇式丙酮酸羧激酶的核苷酸序列。pep羧激酶(ec4.1.1.49)優(yōu)選地是異源酶,優(yōu)選地源于細(xì)菌,更優(yōu)選地具有pep羧激酶活性的酶源于escherichiacoli、mannheimiasp.、actinobacillussp.或anaerobiospirillumsp.,更優(yōu)選地,mannheimiasucciniciproducens或actinobacillussuccinogenes。在一個(gè)實(shí)施方案中,pep羧激酶源于actinobacillussuccinogenes(pcka),其中pcka優(yōu)選地已被修飾為在第120-122位上用daf氨基酸序列代替egy。優(yōu)選地,用與seqidno:6的氨基酸序列具有至少80%、85%、90%、95%、99%或100%的序列同一性的pep羧激酶對根據(jù)本發(fā)明的酵母細(xì)胞進(jìn)行了遺傳修飾。在另一個(gè)優(yōu)選的實(shí)施方案中,根據(jù)本發(fā)明的方法中經(jīng)遺傳修飾的酵母包含編碼延胡索酸還原酶的核苷酸序列。優(yōu)選地,延胡索酸還原酶是異源酶,優(yōu)選地是nad(h)-依賴型延胡索酸還原酶,其可源于任何合適的來源,例如細(xì)菌、真菌、原生動(dòng)物或植物。優(yōu)選地,根據(jù)本發(fā)明的方法中的酵母包含異源的nad(h)-依賴型延胡索酸還原酶,優(yōu)選地源于trypanosomasp.,例如源于trypanosomabrucei。在一個(gè)優(yōu)選的實(shí)施方案中,編碼nad(h)-依賴型延胡索酸還原酶的核苷酸序列在胞質(zhì)溶膠中表達(dá)。在編碼nad(h)-依賴型延胡索酸還原酶的核苷酸序列包含過氧化物酶體或線粒體靶向信號的情況下,可能必須修飾或缺失大量氨基酸(和編碼核苷酸序列中相應(yīng)的核苷酸序列),從而阻止酶的過氧化物酶體或線粒體靶向。過氧化物酶體靶向信號的存在可例如通過etal,nucleicacidresearch2007,35,d815-d822所公開的方法來確定。優(yōu)選地,用與seqidno:7具有至少80%、85%、90%、95%、99%或100%的序列同一性的nad(h)-依賴型延胡索酸還原酶來對根據(jù)本發(fā)明的酵母細(xì)胞進(jìn)行遺傳修飾。在另一個(gè)優(yōu)選的實(shí)施方案中,根據(jù)本發(fā)明的方法中經(jīng)遺傳修飾的酵母包含編碼延胡索酸酶的核苷酸序列,所述延胡索酸酶可以是異源或同源的酶。編碼異源延胡索酸酶的核苷酸序列可以源于任何合適的來源,優(yōu)選地來自微生物來源,優(yōu)選地來自酵母,例如saccharomycescerevisiae,或來自絲狀真菌,例如rhizopusoryzae。優(yōu)選地,根據(jù)本發(fā)明方法中的酵母過表達(dá)編碼與seqidno:8的氨基酸序列具有至少75%、80%、85%、90%、92%、94%、95%、96%、97%、98%或99%或100%的序列同一性的延胡索酸酶的核苷酸序列。在另一個(gè)優(yōu)選的實(shí)施方案中,根據(jù)本發(fā)明的方法中經(jīng)遺傳修飾的酵母還包含編碼蘋果酸脫氫酶(mdh)的核苷酸序列,所述蘋果酸脫氫酶在所述核苷酸序列表達(dá)后在胞質(zhì)溶膠中有活性。優(yōu)選地,mdh缺乏過氧化物酶體或線粒體靶向信號,以將酶定位于胞質(zhì)溶膠中。胞質(zhì)溶膠mdh可以是任何合適的同源或異源蘋果酸脫氫酶。優(yōu)選地,根據(jù)本發(fā)明的酵母細(xì)胞包含編碼下述蘋果酸脫氫酶的核苷酸序列,所述蘋果酸脫氫酶與seqidno:9的氨基酸序列具有至少70%,優(yōu)選地至少75%、80%、85%、90%、92%、94%、95%、96%、97%、98%、99%的序列同一性。在另一實(shí)施方案中,根據(jù)本發(fā)明的方法中經(jīng)遺傳修飾的酵母包含編碼二羧酸轉(zhuǎn)運(yùn)蛋白(優(yōu)選地,蘋果酸轉(zhuǎn)運(yùn)蛋白(mae))的核苷酸序列。二羧酸轉(zhuǎn)運(yùn)蛋白可以是同源或異源的蛋白質(zhì)。優(yōu)選地,二羧酸轉(zhuǎn)運(yùn)蛋白是異源的蛋白質(zhì)。二羧酸轉(zhuǎn)運(yùn)蛋白可源于任何合適的生物,優(yōu)選地源于schizosaccharomycespombe。優(yōu)選地,二羧酸轉(zhuǎn)運(yùn)蛋白是下述蘋果酸轉(zhuǎn)運(yùn)蛋白(mae),所述蘋果酸轉(zhuǎn)運(yùn)蛋白與seqidno:10具有至少80%、85%、90%、95%或99%或100%的序列同一性。優(yōu)選地,根據(jù)本發(fā)明的方法中使用的酵母是包含異源pep-羧激酶、異源nad(p)h-依賴型延胡索酸還原酶、異源延胡索酸酶、異源蘋果酸轉(zhuǎn)運(yùn)蛋白和胞質(zhì)溶膠蘋果酸脫氫酶的經(jīng)遺傳修飾的酵母。這些酶的優(yōu)選的實(shí)施方案如本文上文中定義。序列同一性在本文中被定義為通過比較序列測定的兩條或更多條氨基酸(多肽或蛋白質(zhì))序列或兩條或更多條核酸(多核苷酸)序列之間的關(guān)系。通常,在被比較的序列的整個(gè)長度上比較序列同一性或相似性。在本領(lǐng)域中,“同一性”也表示氨基酸或核酸序列之間的序列相關(guān)度,這根據(jù)情況通過這類序列串之間的匹配測定。測定同一性的優(yōu)選方法被設(shè)計(jì)為在測試的序列之間給予最大匹配。測定同一性和相似性的方法被編碼于公眾可獲得的計(jì)算機(jī)程序中。測定兩條序
