Algae Kits Now Available

In order to make it easier to get started growing algae, I have added kits to the Algae Shop. The basic kit includes your choice of 1 liter of algae culture and 100 liters of growing medium. This is ideal if you already have a growing system or plan on building one. There  are also two kits that include complete growing systems, algae and media.

Check out our Algae Kits page in our Shop. You can also buy the bioreactors and algae cultures individually. 

Algae Education: Post #1 Getting Started Culturing Algae

Algae are perfect organisms to use in the scientific classroom to demonstrate many principals of biology and the use of scientific equipment. Algae can be relatively easy to cultivate on the small scale which can provide a continuous supply of material for students to work with.

A few ideas of ways to work with algae in the classroom:

  • Demonstrate the use of the light microscope. This is a skill that biology students should have. 
  • Measure algal density using spectrophotometer, cell counts and dry weight. These methods are key to algae production and are not difficult to perform. 
  • Identify different types of algae. It is important to be able to identify potential contamination in your cultures. 
  • Setup and carry out experiments. There are endless possibilities here. Test how differences in media, nutrients, light, temperature or other environmental variables can affect algal growth. 

To get started culturing algae you will need:

  • Containers to cultivate the algae. Glass works well, with some kind of lid to minimize evaporation and contamination. 
  • A suitable place to grow the algae. Mainly what you need here is the proper level of light and temperature. 
  • Starter culture of algae. I provide a few of the most popular strains, however many more species are available through culture collections. 
  • A suitable growing media for the algae culture. There are many different kinds of media recipes available and also pre-made media are available. 

I will be adding more content to this website to help facilitate learning about the many different aspects of algae on our planet. Please contact me to let me know what kind of information you would like to see. 

 

Diatoms, Algae and the Environment: a tidbit

I first started working with algae in 1999, during my undergraduate work at Oklahoma State University. My advisor, Bill Henley was working on a project at the Great Salt Plains National Wildlife Refuge to collect and identify the extremophile algae that lived there. In my years working there I became familiar with many of the algae taxa that inhabit inland saline habitats, especially the diatoms. Studying the diatom assemblages of the Salt Plains turned into my Masters Thesis and an enduring interest in diatoms.

Diatoms are of great global importance. To start with, diatoms are responsible for between 20-40% of the earths oxygen production. This fact alone should make you want to hug a diatom. However, this huge contribution to global oxygen supplies is just a byproduct (even considered to be a waste product) of photosynthesis. The primary objective of any diatom is to fix carbon dioxide into energy and biomass. The resulting biomass happens to be tasty and nutritious to many organisms, and is therefore the base of many aquatic food chains, especially in marine systems. So, much of that tasty seafood we love, was once an unpretentious diatom. 

Anyone can quite quickly grasp the difference between having potatoes and not having potatoes. It is somewhat more difficult to establish the consequences of, for example Cyclotella americana Fricke being extirpated from Lake Erie.

Sometimes the high productivity of diatoms can get out of hand, especially in response to nutrient pollution into aquatic habitats. As this story reports, we are seeing an unprecedented bloom of the toxin producing diatom, Pseudo-Nitzschia all along the Pacific coast. 

Our understanding of nature and the environment is incomplete, as stated by Stoermer and Smol in the above quote about potatoes and Cyclotella. And, the limited application of the knowledge we do have may be keeping us from making breakthroughs in areas of environmental remediation and environmental industrialism.
