No shortcuts

The fact that Chlorella grows so slowly isn’t a problem for me personally, I don’t have time to attend to this stuff every day so it kind of works out nicely.  BUT, if I want to come up with projects that are student friendly, they have to fit into a semester and also into their lives.  I had hoped that somewhere out there, there might be a paper showing that you can increase its growth rate in light by adding glucose or some other carbon source.  But no, as shown in this paper (PDF), glucose or galactose CAN support growth of Chlorella in the dark, but its slower than, and does not increase, the light saturated growth rate.

I still need to look up what is known about growth on plates versus liquid cultures.

About SubOptimist

I am an Associate Professor in the Science Department at Georgia Perimeter College, Clarkston. I teach introductory biology courses at both the majors and non-majors level in addition to microbiology. Previous to that I spent 7 years as a postdoctoral researcher on different viruses. While I don't miss being on the "grant treadmill", I think better when I write and miss writing up data for papers and grants; this blog helps me with that a little. And sometimes my kids' insanely funny and cute antics need to be shared with the world. Any view expressed in this blog is that of me personally and not Georgia Perimeter College or the GPC Clarkston Science Department.
