Increasing activity of 2'fucosyllactose transporters endogenous to microbial cells

摘要

A fermentation broth which includes a microbial cell which has been subjected to a condition under which the activity an endogenous transporter for 2′ fucosyllactose is increased. Also provided are methods for increasing export of 2′ fucosyllactose from a microbial cell, methods for identifying an endogenous yeast transporter of 2′ fucosyllactose, and microbial cells genetically engineered to increase the activity of an endogenous transporter of 2′ fucosyllactose.
