Antioxidant Activity of Germicidin A and B Isolated from the Marine-Derived Streptomyces sp. SCS525
Author(s): Grace Choi,Min-Ji Ryu, Yun Gyeong Park and Sang-Jip Nam
Oxidation of lipid compounds in foods reduces their shelf-life, and oxidation in living cells causes damage through the release of free radicals. Synthetic antioxidants for food preservation are phenolic in nature, and thus their use is tightly regulated. On the other hand, naturally occurring antioxidants that have been successfully isolated are limited by low efficacy and high cost. Therefore, the development of safe and low-cost natural antioxidants for use in food production and preservation is needed. Here, we investigated antioxidant activity in extracts from isolated marine bacteria derived from marine sediments. Among them, Streptomyces sp. SCS525 showed strong antioxidant activity as measured by free radical scavenging assays. Bioassay-guided fractionation and spectroscopic dat... view more»
