Project description:Micractinium conductrix SAG 241.80 secretes sugars (especially maltose) at pH 5.7 while very little sugar is found at pH 7.6. Another algae, Chlorella sorokiniana does not secrete sugars at either pH. We evaluated the transcriptional profiles of both species of algae at pH 5.7 and 7.6 to make comparisons in the regulation of potential genes involved in these pathways.
