In this work, we show that lactose transport in&amp;nbsp;&lt;i&gt;K. marxianus&lt;/i&gt;&amp;nbsp;CCT 7735 by lactose-grown cells is mediated by a low-affinity H&lt;sup&gt;+&lt;/sup&gt;-sugar symporter. This system is glucose repressed and able to transport galactose with low affinity. We also observed the activity of a distinct lactose transporter in response to raffinose. Regarding glucose uptake, specificities of at least three low-affinity systems rely on the carbon source available in a given growth medium. Interestingly, it was observed only one high-affinity system is able to transport both glucose and galactose. We also showed that&amp;nbsp;&lt;i&gt;K. marxianus&lt;/i&gt;&amp;nbsp;CCT 7735 regulates the expression of sugar transport systems in response to glucose availability.</style></abstract></record></records></xml>
