酵母菌分离株培养基筛选及菌株优选

Yeast is rich in protein , enzyme system and physiological factors, and it also has many characteristics such as strong polyphagia, easy to be separated and multiplied , produces many kinds of metabolites, and comprehensive utilized broadly and so on, and in forage industry has been widely used. Therefore, it becomes critical to select the best strain and culture for producing the yeast products better. This experiment uses PDA medium, takes advantage of diluted coated board , three yeast isolates from the soil were obtained and compared for their growth traits in different media. A kind of medium was determined for the growth of the yeast isolates, and also a strain of the yeast isolates with good growth traits was got, which lay the foundation for developing high-efficient yeast cultures and relative products.
