Algae Research Supply: Algae Culture Anabaena variabilis

$ 8.00

Anabaena variabilis is a filamentous cyanobacteria. It is photosynthetic and can It also can convert atmospheric nitrogen to ammonia via nitrogen fixation.

Anabaena variabilis is great for studying algae blooms and photosynthesis.  It is often used for reseraching the beginnings of multicellular life due to its filamentous characterization and cellular-differentiation capabilities.

 This culture is great for science fair projects investigating blue green algae blooms.  A variabilis is a freshwater strain that will bloom!  Suggestions on projects include finding ways to make the algae not grow (bleach, salts, grazing animals - basically algae torture)

Algae Research Supply: Algae Culture Chlorella vulgaris

$ 8.00

I caught our operations manager, Danielle, looking intensely at a flask of Chlorella she was swirling then said "this one is my favorite".  When asked why she responded, "Its a nice shade of green".  

 

Chlorella is a genus of single-cell green algae belonging to the phylum Chlorophyta. It is spherical in shape, about 2 to 10 μm in diameter, and is without flagella. Chlorella contains the green photosynthetic pigments chlorophyll-a and -b in its chloroplast. Through photosynthesis, it multiplies rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.

The name Chlorella is taken from the Greek, chloros, meaning green, and the Latin diminutive suffix ella, meaning small. German biochemist and cell physiologist Otto Heinrich Warburg, awarded with the Nobel Prize in Physiology or Medicine in 1931 for his research on cell respiration, also studied photosynthesis in Chlorella. In 1961, Melvin Calvin of the University of California received the Nobel Prize in Chemistry for his research on the pathways of carbon dioxide assimilation in plants using Chlorella.

Many people believe Chlorella can serve as a potential source of food and energy because its photosynthetic efficiency can, in theory, reach 8%,comparable with other highly efficient crops such as sugar cane.

Chlorella is a Chlorophyte (Green algae) it is unicellular, without a flagella.   This culture requires a higher flux of light, but NOT direct sunlight.  Our media works great with this culture.  The best growth temperature is in the low 20s° C.

Each order of algae includes a Culturing Algae Manual.

Should I order a the CULTURE or the CULTURING KIT?  

The culture is just that- algae culture in a bottle.  

The culturing kit is (1) algae culture, (2) algae culturing salts, (3) algae culturing nutrients.

The KIT will get you to a total volume that is much greater than the initial volume of the culture. 

Algae Research Supply: Algae Culture for Isochrysis galbana

$ 8.00

Isochrysis galbana is a great feeder algae.  We know when it is happy and healthy because when you smell it, it smells like low tide!   Isochrysis and similar phytoplankton are contributing factors to the flavor of some fish.  If you like sushi, you will love the smell if Isochrysis.  Some of our coral reef friends love this strain as it brings great pigmentation into the corals.  

This motile strain is fun to grow and is great as a feed stock.

Isochrysis galbana is a microalga. It is an outstanding food for various bivalve larvae and is now widely cultured for use in the bivalve aquaculture industry.  This unicellular is investigated for its high amount of Fucoxanthin (18.23 mg/g dried sample).

Algae Research Supply: Algae Culture Nannochloropsis

$ 8.00

Nannochloropsis is a genus of alga within the heterokont line of eukaryotes it is being investigated for biofuel production. Some Nannochloropsis species have been shown to be suitable for algal biofuel production due to its ease of growth and high oil content (28.7% of dry weight), mainly unsaturated fatty acids and a significant percentage of palmitic acid. It also contains enough unsaturated fatty acid linolenic acid and polyunsaturated acid (>4 double bonds) for a quality biodiesel.

Nannochloropsis is a bulldog of an algae strain.  It is great for science projects as it stays in suspension (it has a very negatively charged cell surface). 

Science project ideas include killing it by varying means (salt, chlorine bleach, too much light, heat, motor oil, sun screen...) or getting it to grow.  Consider measuring the density of the algae over time to quantify growth rate (use or secchi stick to do this.)

Nannochloropsis is another of our favorite algae to grow.  We like it for so many reasons we made bullet points!

• It is difficult to kill, allowing even rookies to seem like professionals
• Nannochloropsis is also euryhaline, which means that it can tolerate a wide range of salinity.  
• The cell surface is very negatively charged, meaning that it will repel it brother and sister cells.  The effect is that it stays in suspension (does not sink easily) very well.  
• Honestly, it is really pretty.  Very green and healthy looking.  Put a flask on your desk and it will grow happily and make you smile when you see it.  

Should I order a the CULTURE or the CULTURING KIT?

The culturing kit is (1) algae culture, (2) algae culturing salts, (3) algae culturing nutrients.

Algae Research Supply: Algae Culture Porphyridium cruentum

$ 8.00

The microalga Porphyridium sp. (Rhodophyta) is a potential source for several products like fatty acids, lipids, cell-wall polysaccharides and pigments. The polysaccharides of this species are sulphated and their structure gives rise to some unique properties that could lead to a broad range of industrial and pharmaceutical applications. Additionally, P. cruentum biomass contains carbohydrates of up to 57 % have been reported. Thus, the combined amount of carbohydrates in biomass and exopolysaccharides of this microalga could potentially provide the source for bio-fuel and pharmaceutical.

• Division: Rhodophyta (Red Algae)
• Water Type: Seawater
• Media: Use Algae Research Supply's Seawater Nutrient Media
• Commonly used for: aquarium feed, aquaculture, study photosynthesis, research, science fair projects
• This is one of the ONLY red microalgae. It is used by researchers to study the red protein based pigment phycoerythrine. Often used by the aquaculture community to bring RED color into filter feeders.
