To simplify the use of minimal medium for fed-batch fermentations, Scarab Genomics offers medium for both the batch phase and feeding phase of fed-batch fermentations. The Korz Feed Stock supplies glucose, magnesium, iron, and trace elements for the feeding stage of Modified Korz Medium fed-batch fermentations. Scarab’s Clean Genome® strains were specifically designed for the production of biotherapeutic protein and DNA. The “cleanest” medium to use for biotherapeutic production is a chemically defined, minimal medium. Accordingly, Modified Korz Minimal Medium has been extensively tested with the Scarab Clean Genome® Strains to verify its ability to support cell growth and the production of recombinant protein. Korz minimal medium is designed for high density fed-batch fermentation of E. coli (Korz et al. 1995, Sharma et al. 2007). The medium consists of phosphate buffer, magnesium, ferric citrate, trace elements, and uses glucose as the carbon source. The same base medium used for optimizing expression in shake flasks can also be used for fed-batch fermentation, thereby providing continuity between the two processes.
Kit Components Korz Feed Stock, 1000 ml Quality Control The media is confirmed for growth of Clean Genome® Strains using liquid culture and confirmed aseptic by no growth in liquid media and agar plates. Storage Conditions For long term storage, store the Korz Feed Stock at 4-12°C and protected from light. For short term storage the Feed Stock may be stored on the bench top at room temp for several days.

Scarab Genomics,LLC成立于2002年,目的是将清洁基因组 ®多重缺失系列(MDS)大肠杆菌商业化,这是由麦迪逊威斯康星大学的Fred Blattner博士的研究产生的。金龟子基因组学已在威斯康星州校友研究基金会获得了专利授权的全球范围内的简化基因组技术。
通过删除超过20%的K-12基因组,对CleanGenome®E.colí进行了生物工程改造。使用合成生物学方法,进行了一系列精确的删除,包括消除了非必需基因,重组基因和移动DNA以及隐性有毒基因。减少基因组可以优化这些大肠杆菌菌株的生产,从而提高遗传稳定性和代谢效率。从常规克隆到大规模生产生物制药,CleanGenome®E.colí是广泛应用的首选菌株。
清洁Genome® 大肠杆菌菌株的 好处
减少的宿主介导的重组可克隆出“不可克隆的”
缺少IS元素可维持克隆完整性
富媒体和最少媒体的强劲增长可带来高产量
去除腐皮防止过早溶解
发酵罐高密度生长
经过验证的基因组减少
与传统的常用大肠杆菌宿主相比,CleanGenome®菌株在实验室克隆,质粒DNA产生和重组蛋白表达方面具有许多独特的优势。圣甲虫的MDS菌株的特殊优势对于生物治疗药物的生产尤其重要。带有附加基因组缺失的MDS菌株已经制成,目前正在测试中。
