Embodiment Construction
[0023] The present invention will be further described below in conjunction with embodiment.
[0024] 1. Isolation and identification of yeast
[0025] (1) Screening of bacterial strains: Use sterile bags to randomly collect soil samples from local orchards, pear orchards, vineyards and other environments, obtain single colonies by dilution plate method, and then select the ones that grow well on the plate and are acceptable Yeast strains with strong fragrance; the second-level screening adopts the Dunbar fermentation method to screen out yeasts with larger gas production, better fermentation power, and better aroma production than the control yeast; the third-level screening also adopts the Durham tube fermentation method, Screen out alcohol resistance, SO resistance 2 , Yeast with good acid resistance was identified as the target strain.
[0026] (2) Identification of yeast species: After preliminary observation of cell morphology, membrane formation, and colony morphology...
