Comparative transcriptome analysis between an original and a recombinant wine yeast strain defective for KNR4/SMI1

ABSTRACT: EKD-13 is among the recently developed mannoprotein overproducing strains. It is a recombinant derivative of the well known EC1118 commercial strain, in which the ORF of all the alleles of KNR4/SMI1 was replaced by different integration cassettes. Lack of Knr4p resulted in a negligible impairment in fermentation kinetics and a net reduction in bentonite requirements to attain complete protein stabilization of white wines made out of natural grape must. In order to improve the technological characterization of this strain, and to better understand the mechanisms underlying mannoprotein oversecretion, we have analyzed kinetics of mannoprotein release and autolysis during fermentation and aging, and we have performed a genome wide expression analysis in two different steps of the fermentation
