Saccharomyces cerevisiae QLJJ61 and application thereof in synthesis of cytidine triphosphate

The invention relates to saccharomyces cerevisiae QLJJ61 and application thereof in synthesis of cytidine triphosphate, and belongs to the technical field of bioengineering. The invention provides the saccharomyces cerevisiae QLJJ61 with excellent cytidine triphosphate synthesis capability, and the preservation number is GDMCC No.62834. Compared with an original strain, the saccharomyces cerevisiae QLJJ61 has the advantages that the beer brewing index is not obviously changed, the stable production of high-quality beer can be realized, and meanwhile, the yield of the saccharomyces cerevisiae QLJJ61 is greatly improved. The collected waste saccharomyces cerevisiae QLJJ61 can be used for preparing more high value-added product cytidine triphosphate, so that the output value and benefit of the beer industry are improved. 本发明涉及一株酿酒酵母QLJJ61及其在合成胞苷三磷酸中的应用，属于生物工程技术领域。本发明提供了一株具有优异的胞苷三磷酸合成能力的酿酒酵母QLJJ61，保藏编号为GDMCC No.62834，与出发菌株相比，该酿酒酵母QLJJ61的啤酒酿造指标并未发生明显变化，可在实现高品质啤酒稳定生产的同时，收集到的废弃酿酒酵母QLJJ61能够用于制备更多高附加值产物胞苷三磷酸，从而提高啤酒工业的
