Chlorella Library
Chlorella is now regarded as a synonym for health food. However, do you really know about chlorella? Here in "Chlorella Library" provides you basic knowledge and related information about chlorella in detail.
Number6:C.G.F. (Chlorella Growth Factor)
[C.G.F.] - a component contained only in chlorella
It is known from a long time ago that certain parts of plants at certain times contain active substance that promotes differentiation and proliferation (physiological phenomena) of organismic plants. The cell of chlorella, which is a kind of plants also includes unique growth accelerator factor called "C.G.F. (Chlorella Growth Factor)." While animals including human beings and plants multiply their cell by binary fission, chlorella divides its cell into four every 20 to 24 hours, and has tremendous life force. It is said that this involves the C.G.F. deeply. The C.G.F. is identified only in chlorella, and a rare substance. Unfortunately, the research has not entirely shown what kind of structures C.G.F. has or what kind of constituents work, however the following constituents the C.G.F. has are revealed.
Structurally it is a complex of nucleic acid including sulfur and amino acid. The sugar part of nucleic acid is formed by glucose mainly and others such as mannose, rhamnose, arabinose, galactose, xylose, and also amino acid composition of peptide is formed by glutamic acid, asparagine acid, alanin, serine, glycine, proline. These constituents are considered to work synergistically. Structure of C.G.F.(Chlorella Growth Factor)

C.G.F. content depends on species of chlorella
PT. Sun Chlorella Indonesia ManufacturingThere are many species of chlorella, and the C.G.F. content entirely varies depends on species and culture method. Chlorella pyrenoidosa has the largest amount of C.G.F. than other species, and chlorella cultured outside under full exposure to sunlight has larger amount of C.G.F. than one cultured in tank from the aspect of culture method.

Certainly the tank culture has the advantage of being able to control temperature of culture solution and nutrients, prevent contamination, and increase the concentration of chlorella in culture solution. However, chlorella cannot photosynthesize, and the chlorella harvested differs from chlorella cultured outside from the standpoint of its constituent because it is tank-cultured in a dark place. This is similar to the way vegetables under garden farming differ from in greenhouse in taste and nutrients.

Difference between chlorella and spirulina
Chlorella significantly draws a line between other green foods such as spirulina because chlorella contains C.G.F.. It would not be an exaggeration to say that C.G.F. that promotes growth of cell and maintains health of organism is the most valuable ingredient in other active substances in chlorella.
