Description

Technical Field

[0001] The invention relates to the technical field of dough fermentation, and more specifically to a dough low-mix bacteria fermentation method. Background Art

[0002] Fermentation refers to the process of allowing yeast to fully reproduce and produce gas under certain temperature and humidity conditions, thereby causing the dough to expand. When yeast converts starch into sugar and consumes it in an aerobic environment inside the dough, it will release carbon dioxide gas. At this time, the volume of the dough will swell and it will rise. Yeast is a eukaryotic receptor cell commonly used in gene cloning experiments. It is as convenient to cultivate yeast as to cultivate Escherichia coli. There are many types of yeast cloning vectors. Yeast also has plasmids. This 2μm long plasmid is called a 2μm plasmid, which is about 6300bp. This plasmid exists outside the chromosome in the cell nucleus for at least some time. The 2μm plasmid and the plasmid in Escherichia coli can be used to construct a shuttle plasmid that can shuttle between bacteria and yeast cells. Yeast cloning vectors are all constructed on this basis. Yeast is a unicellular fungus, not a unit of systematic evolutionary classification. It is a tiny unicellular microorganism that is invisible to the naked eye. It can ferment sugar into alcohol and carbon dioxide. It is distributed throughout nature. It is a typical heterotrophic facultative anaerobic microorganism that can survive both aerobic and anaerobic conditions and is a natural leavening agent.

During the mixing and fermentation process, it is easy for too many bacteria to exist, which will affect the reproduction of yeast.
