Number1:540 million years of memories reminded in Chlorella's genes
 
Chlorella - a gift from nature in ancient time
Chlorella, which is attracting widespread popularity today as a basic health food, has an extremely long history. It is said that it is 4.6 billion years ago that earth came into existence, and 3.5-3.8 billion years ago that organisms first came into existence on earth. It was over 2 billion years ago during the pre-Cambrian period when eukaryotic cell, which belongs to the same kind as Chlorella first came into existence on earth. This is demonstrated by chlorella - like fossil excavated from a stratum from the pre-Cambrian period. From the latest gene analysis of Chlorella, it turned out that it was 540 million years ago that Chlorella and Chlamydomonas diverged from a common ancestor. Since then, chlorella has survived every convulsion of nature in the long history, and remained unchanged until today. Pre-Cambrian chlorella-like fossil

Why could chlorella in the long history survived every convulsion of nature and remain unchanged until today? The first reason is that chlorella is so small with 3 to 8 micrometers in diameter, and also covered by tough outer cell wall protecting in the internal organs from environmental changes outside. The second reason is that it has rapid reproductive ability. There are two ways in reproduction of creatures, one is sexual reproduction and other is asexual reproduction. Chlorella is asexual reproducible plant. It divides four times every 20-24 hours. One cell reproduces 4 new cells the next day, and 16 cells the day after... Chlorella has kept reproducing since over 2 billion years ago.

Chlorella widely watched as a savior of food shortages
 
The 1930s Chlorella researched worldwide as future food source It was only 100 years ago from now, the end of 19 century, when human beings discovered live chlorella. Chlorella was first discovered by a Dutch microbiologist, Dr. Bilink. At that time, chlorella was named after "chlor" which means green and "ella" which means a small thing. At the very end of the 1930s, Dr. Lidner in Germany reported that chlorella contains a volume of protein of good quality, and it caused a sensation in the world. Then many researches on chlorella were performed in the world under an idea that chlorella could be useful as future food source.
 
After World War2 Chlorella researched as space food Although the researches were interrupted during World War II, the studies were resumed after the war. In the U.S and the former U.S.S.R, they investigated Chlorella as a space food, and began to cultivate it. In Japan, in order to resolve the food insecurity after defeat in the war, the research on full-scale culture of chlorella was started suggested by Carnegie Research Laboratory. However, the interest in Chlorella had gradually vanished due to the low harvesting efficiency and high cost as well as bumper crop of rice.
 
The 1960s Chlorella growing as a synonym for health food Later on, being recognized its health effects, chlorella attracted attention again. In the middle of the 1960s, chlorella came into the world market as health food, and became popular in the 1970s. Since then, its market has been growing as a synonym of health food.
