CO2 in Planted Aquaria

CO2 is beyond comparison the most important of all plant nutrients. Without sufficient CO2, plants cannot photosynthesize and convert into energy-rich sugars, starch and all the other carbon-containing molecules that constitute a plant. It may seem odd to look at CO2 as a plant nutrient. When growing terrestrial plants, we are used to providing light, water and nutrients, but never CO2. is art...

Isolation of Pure Cultures of Algae from Contaminated Cultures.

Algal cultures have been freed of bacterial contamination by a procedure involving treatment with a detergent and phenol, followed by plating on an agar medium for selection of pure cultures.
