5-AminoLevulinic Acid (ALA) is a kind of amino acid found naturally in organisms. |
|
It is a constituent in both chlorophyll and heme (blood), and is critical for living organisms. |
|
ALA and derivatives are involved in a wide range of biological activity, with diverse applications reported. |
 |
Increase leaf greenness |
|
Potos leaves treated with appropriate concentration of ALA become greenery and color lasted longer. |

COSMO OIL company produce ALA
by the fermentation method ! |
| COSMO OIL found the bacteria which produce 5-aminolevulinic acid. |
ABSTRACT
Generally, photosynthetic bacteria, especially purple-nonsulfur bacteria, accumulates ALA under light illumination in the presence of levulinic acid. However, the use of light illumination on an industrial scale is not economical, particularly in the case of high cell density cultivation. COSMO OIL tried to find out strains which can produce ALA in the absence of light. Finally, after we had tested more than 100,000 mutants, COSMO OIL found the high efficient strain in an industrial scale. |
