Abstract

The invention discloses a probe for absolute quantification of schizosaccharomyces pombe, a kit and application, and belongs to the fields of biology, fermentation and detection. According to the probe for absolute quantification of schizosaccharomyces pombe and the kit, the total amount of schizosaccharomyces pombe can be detected, and can be used for detecting and quantifying the schizosaccharomyces pombe without expensive instruments, and the quantification work can be rapidly completed within 2.5h. Meanwhile, the sample used in the present invention need no nucleic acid extraction. Quantification of schizosaccharomyces pombe based on the probe and the detection kit provided by the invention has the characteristics of rapidness, convenience, cheapness and accuracy.

Description

technical field [0001] The invention relates to an absolute quantitative probe, kit and application of Schizosaccharomyces pombe, belonging to the fields of biology, fermentation and detection. Background technique [0002] Schizosaccharomyces pombe is a functional microorganism that widely exists in traditional brewing systems, such as liquor and wine. In the study of liquor, Schizosaccharomyces pombe can have strong acid resistance, and can reduce the accumulation of acetic acid and regulate the bacterial flora structure. Therefore, real-time tracking of the biomass of Schizosaccharomyces pombe is important for judging the stability of fermentation batches and the regulation of fermentation parameters. Guiding significance. However, at present, most traditional fermented food systems are multi-strain co-fermentation systems, and the content of Schizosaccharomyces pombe in samples cannot be judged by simple OD colorimetry, although fluorescent quantitative PCR combined wit...
