Basic questions about algae
Posted 30 November 2009 - 06:24 AM
I'm looking for some very basic information about algae, about which I know nothing -- I'm trying to help my son (age 14) design a science fair experiment. He wants to do something with algae, e.g. see what effect different culture conditions (lighting, temperature, pH) have on growth rate.
First, what is a good genus/species of algae to use? I assume freshwater species are easier to deal with than saltwater species? Maybe he could use a couple (one green, one red, for example).
Second, what is a good general-purpose (liquid) media for use in growing such species? A recipe would be appreciated, one that is hopefully not too exotic...
Third, what's a good way to measure growth rate in such a culture? Accumulation of dissolved oxygen? Biomass measurements? Are there somewhat simple (science fair level) ways of measuring such things over time with a reasonable degree of accuracy?
Finally, how rapidly does algae grow? I'm used to bacterial cultures, where changes are apparent over a matter of hours. Do algal cultures produce measurable changes over a similar time period, or is it only apparent over a matter of days or weeks?
Any ideas or discussion greatly appreciated...

I did find this website though, it should be some help...
Also check out the links at the bottom of this wikipedia page...

Any algae researchers here at the BioForum?

just read this paper recently and i think you might find some of the references useful. i believe the main focus is on spirulina.
