However, the survival of most of the current yeast has high requirements on the environmental pH, and generally can only survive in a relatively narrow pH range.
For example, currently commercially available baker’s yeast can only survive well in the pH range of 3 to 8, but cannot survive at all in the alkaline range above pH 8, so pH 8 is the limit pH value for the strain’s survival
[0004] In addition, the proliferation performance of the existing yeast is not ideal, and it is relatively difficult to separate out after cultivation, which is not conducive to industrial utilization

Embodiment
[0023] A strain of marine yeast with high proliferative performance, named: Marine yeast WHH-2 strain, which was deposited in the General Microorganism Center of China Committee for the Collection of Microbial Cultures on July 17, 2017, and its preservation number is CGMCCNo. 14432.
[0024] Screening of marine yeast WHH-2 strain:
[0025] In order to screen out strains with excellent culture performance and high cell yield after culture, one of the best strains, marine yeast WHH-2 strain, was further selected from the 535 marine yeast strains screened in the previous stage.
[0026] The bacterial strain Saccharomyces cerevisiae WHH-2 strain of the present invention is obtained by screening from the seawater at a depth of 5 meters below the sea surface at a place about 10 kilometers away from land on the east coast of Zhoushan Island in my country. Before sampling, the box containing the ice had been completely sterilized with 70% ethanol, and the collected seawater was put i...

The present invention relates to the field of microorganisms, and discloses a strain of marine yeast with high proliferative performance, named: marine yeast WHH-2 strain, which has been preserved in China Microbiological Cultures Preservation Management Committee Common Microorganisms on July 17, 2017 Center, its deposit number is CGMCC No.14432. The yeast of the present invention can still have a high survival rate in a relatively high alkaline environment of pH 9-11, and has a very strong proliferation performance, and is easy to separate out after cultivation, which is beneficial to industrial utilization.
Description
technical field [0001] The invention relates to the field of microorganisms, in particular to a strain of marine yeast with high proliferation performance. Background technique [0002] Yeast is a single-celled fungus, a tiny single-celled microorganism invisible to the naked eye, which can ferment sugar into alcohol and carbon dioxide. It is distributed throughout nature and is a typical facultative anaerobic microorganism. It can survive under all conditions and is a natural leavening agent. [0003] In the field of beverages, yeast has also been widely used. However, the survival of most of the present yeasts has high requirements on the pH of the environment, and generally they can only survive in a relatively narrow pH range. For example, the currently commercially available baker’s yeast can only survive well in the pH range of 3 to 8, but cannot survive at all in the alkaline range above pH 8, so pH 8 is the limit pH value for the strain’s survival. [0004] In add...
