Abstract:Saccharomycopsis fibuligera belongs to yeast，also known as sac buckle Saccharomycopsis，endomycopsis fibuligera；widely exists in all kinds of yeast，can produce amylase，acid protease in the fermentation industry，beta glucosidase，and its production of enzyme had high activity，in addition the study found that，a lot of Saccharomycopsis fibuligera also has certain aroma producing ester production as well as the use of distiller's ability to produce high quality and low cost of grains of single cell protein feed.In the wine industry in the activity of these enzymes determines Saccharomycopsis fibuligera by all kinds of raw materials as substrates，fermentation of alcohol；the aroma producing ability and increase alcohol ester production in different degree under the condition of aroma，rich flavor of wine.At the same time and it can use distiller's grain production of protein feed，the ability to determine Saccharomycopsis fibuligera has research value and great potential in the brewing industry，this paper summarizes the physiological and biochemical characteristics of Saccharomycopsis fibuligera，strain breeding，application of enzyme producing and aroma producing characteristics and yield of ester producing lees protein feed，provide new ideas and methods for the rational use of Saccharomycopsis fibuligera in the brewing industry.
