【正文】 301 中,得到含有 3 個 aveB IV基因表達單元的突變株 MYG1118,且突變株的生產(chǎn)效率很高,為工業(yè)應(yīng)用提供了跟好的菌株。 均勻設(shè)計法優(yōu)化柔紅霉素發(fā)酵培養(yǎng)基 [5],有研究表明均勻設(shè)計利用玉米漿、麩皮、麩質(zhì)粉作為培養(yǎng)基原料,實現(xiàn)了紅霉素發(fā)酵培養(yǎng)基改良,進一步降低生產(chǎn)成本。有研究表明利用中心組合設(shè)計,采用響應(yīng)面分析法對目前紅霉素發(fā)酵生產(chǎn)過程常用的幾種碳源和氮源進行篩選和優(yōu)化,優(yōu)選出淀粉和糊精作為混合碳源,豆餅粉和玉米漿作為混合氮源,而不使用成本較高且消耗量大的葡萄糖和蛋白胨等。但是發(fā)酵中添加油脂的量需進行培養(yǎng)基優(yōu)化測定。 紅霉素作為大環(huán)內(nèi)酯類抗生素,有研究表明通過在培養(yǎng)基中加入油脂類緩慢利用碳源,來促進紅霉素的發(fā)酵生產(chǎn),得出油脂的不飽和性越高,紅霉素產(chǎn)量越高。 3 通過對紅霉素發(fā)酵培養(yǎng)基的優(yōu)化 [1],有研究通過實驗得出一優(yōu)化的培養(yǎng)基的組成配比,紅霉素發(fā)酵培養(yǎng)基中的 C/N過高或過低都不能取得較高的發(fā)酵水 平,研究者針對 UL5菌株得出相應(yīng)結(jié)論,但其它菌種并沒有說明,因此在使用 UL5外的菌株時,可以參考本文進行優(yōu)化培養(yǎng)基組成配比,達到相應(yīng)的效果。選育以誘變育種為主要方法。 紅霉素工廠的設(shè)計首先注重的是菌種選育,培養(yǎng)基的組成,然后進行發(fā)酵生產(chǎn)。隨第二代紅霉素 (如阿奇霉素、羅紅霉素、克拉霉素等 )、第三代紅霉素 (如泰利霉素 )在日本和歐洲上市,國內(nèi)外市場對紅霉素的 需求大大增加。目前國外發(fā)酵單位已達 8 00012 000 μg /ml,而國內(nèi)大多企業(yè)紅霉素發(fā)酵水平卻一直在 4 0005 000μg /ml[1]。近幾年紅霉素衍生物的興起,大大刺激了母體紅霉素的需求 [1]。 Design 1 目錄 ..................................................................................................................................2 紅霉素的理化性質(zhì) ...............................................................................................2 國內(nèi)生產(chǎn)現(xiàn)狀 .......................................................................................................2 紅霉素銷售狀況 ...................................................................................................2 紅霉素生產(chǎn)的改善 ................................................................................................2 紅霉素生產(chǎn)過程的控制技術(shù) ...............................................................................4 紅霉素提取脫色方面的研究 ...............................................................................6 紅霉素生產(chǎn)過程相關(guān)的設(shè)備 ...............................................................................6 ..................................................................................................8 工藝原則 ...............................................................................................................8 工藝流程的確定 ...................................................................................................8 ........................................................................................................................10 設(shè)計指標及主要物性參數(shù) ..................................................................................10 發(fā)酵工段工藝計算 .............................................................................................13 無菌空氣處理 ......................................................................................................36 提取工段工藝計算 ..............................................................................................37 三廢的處理 ..........................................................................................................39 ............................................................................................................41 工廠總平面布置設(shè) 計原則 ..................................................................................41 車間布置設(shè)計原則 ..............................................................................................41 ................................................................................................................................43 ........................................................................................................................44 致 謝 ...............................................................................................................................46 2 紅霉素的理化性質(zhì) 紅霉素 (Erythromycin, Er)為十四元大環(huán)內(nèi)酯類抗生素,是紅色糖多孢菌(Saccharopolyspora erythraea)的次級代謝產(chǎn)物,包括 ErAErF,其中 ErA的抑菌活性最高。s volume is 100 m3. We need eight fermenters, four m3 First seed fermenters, four 4 m3 Second seed fermenters, four 32 m3 Third seed fermenters . The yield coefficient of Extraction process is 70%. Finally, we chose 6 Plate and frame filter presses, 3 Solvent extraction pools and 6 Centrifuge. All in all ,the designation meets the III normal requirements and meet the national standards . In the end ,there is a Fermentation floorplan (1), Flow chat (1), Fermentation process equipment general arrangement (1), Extraction process equipment general arrangement (1), Fermenter orthographic views (1) and pilation particular data instruction booklet. Key word: Erythromycin。 關(guān)鍵詞 : 紅霉素;工藝流 程;設(shè)計 II An Initial Technological Design for 330 t/a Erythromycin Factory Mao Hailong Biology Engineering 0801, School of Environmental and Biological Engineering, LiaoNing Shihua University, 113001, Fushun Abstract This subject is an initial technological design for Erythromycin with year output of 330 ton. According to the requirement, the process of erythromycin production and the calculation of the mass balance and heat quantity balance are pleted. In this subject, all of them processes are expounded in detail. All the contents are based on the academic calculations. We refer to the practical designs in panies and make our best to approach to the practice. it mainly includes the production craft each kind of target, the equipment chooses the shape design calculation, material of the graduated arm of a steelyard calculation, the water, the electricity, the steam estimate as well as the flow chart design. The entire design process strives to guarantee the achievement of the design requirements and the actual also notice the environmental protection and energy conservation, which can bring a better ine, reduce the diverse impact on the environment, and reduce the pressure on the environment. Under the condition of the final erythromycin39。 符合設(shè)計的基本要求,同時滿足國家標準。最終理論計算結(jié)果在總收率 65%的前提下,在發(fā)酵工段檢測紅霉素含量 14000 U/mL,成品單位為 720 U/mg,最終確定選用發(fā)酵罐體積為 100 m3( 8 個),一級種子發(fā)酵罐 m3( 4 個),二級種子發(fā)酵罐 4 m3( 4 個), 三級種子罐 32 m3( 4 個)。其主要包括生產(chǎn)工藝的各種指標、設(shè)備選形設(shè)計計算、物料衡算、水、電、汽的估算以及工藝流程圖的設(shè)計。 I 330噸 /年紅霉素 生產(chǎn)工廠 的初步設(shè)計 摘 要 本設(shè)計是為 330 噸 /年紅霉素生產(chǎn)工廠而進行的初步工藝設(shè)計。根據(jù)畢業(yè)設(shè)計大綱和設(shè)計任務(wù)要求該設(shè)計分別對各工藝作了詳細闡述,以理論計算為依據(jù),以實際工廠設(shè)計為參考,力求接近并切合實際。整個設(shè)計過程在保證達到設(shè)計要求和實際需要的前提下力求環(huán)保節(jié)能,從而能夠
