Saccharomyces cerevisiae culture as well as preparation method and application of saccharomyces cerevisiae culture

The invention discloses a saccharomyces cerevisiae culture as well as a preparation method and application of saccharomyces cerevisiae culture. The preparation method comprises the following steps: performing seed culture of saccharomyces cerevisiae to obtain a saccharomyces cerevisiae seed culture; inoculating a liquid medium with the saccharomyces cerevisiae seed culture for aerobic fermentation to obtain a saccharomyces cerevisiae liquid culture; inoculating the saccharomyces cerevisiae liquid culture into a solid medium for anaerobic fermentation; after the fermentation, performing wall breaking treatment of the saccharomyces cerevisiae; and drying the saccharomyces cerevisiae solid culture after the wall breaking treatment to obtain the saccharomyces cerevisiae culture. Being as micro-ecological product replacing antibiotics, the saccharomyces cerevisiae culture disclosed by the invention is an urgent need of the breeding industry and plays an increasingly important role in ecological breeding production
