In a two-stage chemostat system, the volumes of the first and second reactors are V₁ = 500 l and V₂ = 300 l, respectively. The first reactor is used for biomass production and the second is for a secondary metabolite formation. The feed flow rate to the first reactor is F = 100 l/h, and the glucose concentration in the feed is S = 5.0 g/l. Use the following constants for the cells.

Determine glucose concentration in the effluent of the first stage. _____________________

#Section 6: Plant, Animal and Microbial Biotechnology

The non-reducing sugar sucrose is most commonly translocated in the phloem rather than reducing sugar. Why?

a.) because they are less reactive than their reducing counterparts

b.) because sucrose contains more energy than a monosaccharides

c.) because the ketone or aldehyde group is reduced to an alcohol or combined with a similar group on another sugar so as not to be oxidized
