How to judge the quality of chlorella concentrate?

A The culture water of Chlorella should not contain diseases, otherwise the concentrated solution will cause diseases in the water used;

B The cultivation of chlorella should not contain cyanobacteria and other weedy algae bacteria. The blooms brought by these cyanobacteria to healthy waters will poison the cultivated species, reduce the fertilizers in the waters, inhibit the growth of healthy plankton, and deteriorate the water ecology.

C The counting method should be scientific. The highest concentration of chlorella in natural water culture is 10 million cells per milliliter. If it is concentrated, it will be up to 1 billion cells. The tens of billions are said to contain bacteria and virus cells. The concentrated solution itself spreads diseases and cyanobacteria.

D Microscopic examination can see intact chlorella cells, and those that cannot see chlorella cells are just nutrient solutions. Living chlorella cells determine whether the population advantage can overcome other cyanobacteria and viruses to obtain water nutrition So as to inhibit the growth of other harmful algae bacteria! The other is that the cells must be intact. If you see a lot of broken cells, it is centrifuged. The effect of this kind of chlorella is greatly reduced.
