    1. The results presented here assess three different aspectsofF. oxysporumethanol tolerance (effects on growth,enzymes, fermenting ability) for the use of a micro-organism in a bioethanol production process and showthatF. oxysporumcan be used in a biorefinery both asa pentose fermenting and enzyme producing micro-organism.

      Restated purpose of the experiment

    2. The effects of ethanol on growth ofF. oxysporum(aer-obic conditions) were more severe when xylose was thecarbon source

      The ethanol effect on F. Oxysporum growth on xylose showed to reach a maximum biomass concentration of 4 g/L where on glucose it was 3g/L, therefore the effects of ethanol showed more severe effects on the over all growth

    3. Figure 1

      This graph displays the effect of F. oxysporum growth on glucose. The test with no ethanol added had the largest biomass at 3g/L, where the 6% w/v initial ethanol had the lowest biomass. The graph shows a trend where the more w/v initial ethanol, the lower the biomass.

    4. In your own words, what is the biologicalquestion that the researchers are asking?

      Does ethanol have and effect on growth and performance under aerobic and micro-aerobic conditions?

    5. Ethanol, like other organic molecules such asbutanol or acetone, binds on the non-catalytic region ofthe enzyme, causing changes in the shape of the proteinmolecule, which in turn affects the catalytic activity.

      is this similar to the example in class where enzymes changed their shape to break the stick, releasing ATP?

    6. hexoses but also frompentoses

      hexose: simple sugar molecule with six carbons vs pentose:simple sugar molecule with five carbon
