It is there. In different Finnish waters, this tiny little thing. Hegewald, Padisák, and Friedl (2007) found that this little thing differed markedly from other look-a-like algae and give a firm description of the differences in their article. A new family - Loboceae E. Hegewald - and a new genus - Pseudoteraëdriella Hegewald - was established in the Class Eustigmatophyceae Hibberd - and look: Pseudotetraëdriella kamillae Hegewald & Padisák had found it's place in the taxonomic tree. One might easily overlook it. Or mix it with Tetraëdron minimum or Tetraëdriella jovetii, but it is different....

An Indian company NUALGI NANOBIOTECH makes the product "Nualgi" to solve a wide range of problems: * to boost the growth of prawns and fishes in aquaculture ponds * to treat sewagewater, polluted and effluent waters and to reduce COD, BOD, color and bad odour in them* to prevent growth of toxic algal species called 'red tides' in the seaand even * to absorb global carbon dioxide and reduce greenhouse gases thereby solving global warming problem.All this is done by our little friends, the algae. In this case specifically the diatom algae. The idea is to stimulate the growth of the diatoms, ...
