Since its establishment in 1992 as a corporate-affiliated research institute, the biotechnology lab of Cheil Bio Co., Ltd. has been
striving to develop market competitive products with the aim of improving the health of livestock.

Cheil Bio lab developed red yeast and mineral yeast that produce Astaxanthin with the start of the commercialization of “Saccharo culture”,
the first active yeast culture in Korea, in 1990, and succeeded in domestic sales and exports through self-development and
mass production of oxytetracycline and colistin among antibiotics that relied on all imports.

In recent livestock projects, regulations on antibiotics are being strengthened to meet the demand for safe food, and in addition,
environmental regulations such as the improvement of the livestock environment and a ban on marine dumping of
livestock waste are also increasing.In line with this trend, their laboratory is conducting extensive research on the theme
of three areas which are antibiotic substitutes, environmental improvements, and formulation improvement
