Although expression of both the Gxf1 and the Sut1 transporter increased the xylose transport performance, the effect of the Gxf1 transporter was significantly more pronounced.
Kinetic characterization of S. cerevisiae strains expressing the Gxf1 and Sut1 transporters showed increased xylose transport performance compared with the control strain expressing only native transporters.
Khadaroo and Seetanah [8] have argued that growth in infrastructure is defined as an indicator for higher transport performance or lower transportation costs.
Expression of the C. intermedia Gxf1 transporter and the P. stipitis Sut1 transporter was thus seen to increase the transport performance compared with the reference strain expressing only native transporters.
In particular, the Gxf1 transporter increased the overall xylose transport performance by three times with respect to the control strain, which is comparable with results from previous studies [ 9, 23].
Cultivation at the low glucose concentration (0.5 g/L) yielded the highest xylose transport performance, which was comparable with cells expressing the Gxf1 transporter during cultivation on 20 g/L glucose.
Unpublished figures presented to a special cabinet meeting by Labour pollster Philip Gould warned ministers that the public had given the government's transport performance a rating of minus 49%.
Service reliability is a key determinant of public transport performance.
A standardized set of transport performance indicators becomes, hence, essential for monitoring the implemented policies.
For each test, the amount of cuttings transport performance (CTP) was determined from weight measurements.
In all figures, cuttings transport performance (CTP) has been plotted versus viscosity.
