Evaluation of Antioxidant Activity in Kocuria Asb107 Extraction

Article excerpt

Background: Carotenoid pigment as extinguisher com- pounds of reactive oxygen species, are considered one ad- vantage ecological bacterial species under oxidative condi- tions. Bacterial colonies of Kocuria ASB107 strains have or- ange carotenoid pigments that can be used in industries. The purpose of this study was measurement and comparison of the antioxidant power of the bacterial extracts under different culture conditions.

Methods: In this study, content of carotenoids and plenolic compounds were assayed, then antioxidant activity of Ko- curia bacterial extracts were studied using three methods of antioxidant power assay (metal chelating ability, reduced power assay and deterrence of beta carotene whiteness method). The experiments were done in a statistical random- ized complete block design and then data analyzed using one- way ANOVA test.

Results: In all three methods, there are a close correlation between antioxidant activity of the methanolic extracts and their carotenoids and phenolic compounds contents. …
