Plan

Aim:Create yeast that can be used to make sweet and low energy bread

Methods:
1.Clone the glu1 (glucoamylase) from Saccharomycopsis fibuligera and insert it in the yeast chromosome by homologous recombination.
2-a Clone mtlD (mannitol synthase) from E.coli and insert it in the yeast chromosome by homologous recombination
|
v
Replace gpd1 gene by mtlD and gpd2 gene by glu1

2-b Clone xylose isomerase gene and D-tagatose 3-epimerase gene from Mesorhizobium loti.
|
v
Replace gpd1 gene by D-tagatose 3-epimerase gene and gpd2 gene by glu1. Transform a plasmid coding xylose isomerase gene.
