摘要： The present invention relates to mutated and/or transformed microorganisms for the synthesis of various compounds. More specifically, the present invention discloses microorganisms mutated in the genes encoding for the regulators ArcA and IclR. The latter mutations result in a significant upregulation of the genes that are part of the colanic acid operon. Hence, said microorganisms are useful for the synthesis of any compound being part of the colanic acid pathway such as GDP-fucose, GDP-mannose and colanic acid, and/or, can be further used –starting form GDP-fucose as a precursor-to synthesize fucosylated oligosaccharides or -starting from GDP-mannose as a precursor –to synthesize mannosylated oligosaccharides. In addition, mutations in the genes coding for the transcriptional regulators ArcA and IclR lead to an acid resistance phenotype in the exponential growth phase allowing the synthesis of pH sensitive molecules or organic acids.
摘要翻译：本发明涉及用于合成各种化合物的突变和/或转化的微生物。更具体地，本发明公开了在编码稳定剂ArcA和IclR的基因中突变的微生物。后一种突变导致作为荚蛋酸操纵子一部分的基因的显着上调。因此，所述微生物可用于合成作为荚状酸途径的一部分的任何化合物，例如GDP-岩藻糖，GDP-甘露糖和col烷酸，和/或可进一步使用 - 以GDP-岩藻糖为起始剂，合成岩藻糖化寡糖或从GDP-甘露糖作为前体开始合成甘露糖基化寡糖。此外，编码转录调节因子ArcA和IclR的基因中的突变导致指数生长期的耐酸性表型，允许合成pH敏感的分子或有机酸。
