ence that the transport of the starting material, galactose, into the cell was a limiting factor.
To resolve that issue, they treated the bacteria with very low concentrations of detergentsjust enough to make their cell walls leaky, according to the researchers. The galactose was able to get in and tagatose released from the cells, allowing the enzyme to convert galactose to tagatose at a faster rate, shaving a couple hours off the time needed to get to 85% yield at 50 degrees Celsius.
