DNA barcode, primers, kit and method, and applications thereof

Abstract

The invention specifically relates to a DNA barcode, primers, a kit and a method for identifying a strain of Blastobotrys adeninivorans, and applications thereof. The DNA barcode can accurately identify a Pu'er tea fermentation strain, i.e., Blastobotrys adeninivorans TMCC 70007, and can quickly and accurately identify the strain from confusing strains or other strains of the same species.

Description

technical field [0001] The invention belongs to the field of species and bacterial strain identification, and specifically relates to DNA barcodes, primers, kits, methods and applications. Background technique [0002] Pu-erh tea is a post-fermented tea with the geographical indication of Yunnan. It uses large-leaf sun-dried green tea as raw material and is made through a series of processes. The traditional production process of Pu'er tea is as follows: the picked fresh tea leaves are rolled, sun-dried, impurity-removed, tide-watered, heaped, dried, sieved, pressed and molded, and packaged for delivery. In the production of Pu-erh tea, the heaping fermentation process is the main factor to form the quality of Pu-erh tea. During this process, the internal components of the tea such as tea polyphenols, caffeine and some polysaccharides have undergone tremendous changes, making Pu-erh tea The special flavor, taste, quality and various health benefits of tea. [0003] In the ...

AI Technical Summary

Problems solved by technology

In recent years, due to the increasing market demand, many small-scale manufacturers lack systematic and in-depth research on Pu-erh tea, and wantonly abuse many other people's patents for profit. A series of methods, such as Pu’er tea processing and production, have greatly damaged the economic interests of some Pu’er tea production enterprises with relevant patents.
