Antibacterial Activities of Red Colored Radish Types (Raphanus sativus L.)

Abstract

The root parts of red skin colored radish cultivars cv. Antep and cv. Cherry Belle which are belongs to Raphanus sativus L. were harvested from Erzurum region of Turkey and their methanol extracts were evaluated for antibacterial activity against 52 food borne bacteria by using disc diffusion assay. Extracts had a broad-spectrum antibacterial activity against food borne bacteria in broth micro dilution bioassays. Maximum antibacterial activity was observed against Arthrobacter ilicis, Corynebacterium ammoniagenes, Enterobacter hormaechei, Kocuria rosea, Neisseria subflava, Pantoea agglomerans, Proteus vulgaris, Psychrobacter immobilis and Shigella dysenteriae. However, cv. Antep showed antibacterial activity against Bacillus sphaericus and Corynebacterium flavescens and cv. Cherry Belle showed antibacterial activity against Arthrobacter atrocyaneus as well as. These inhibitory effects are interesting in relation to the prevention of microbial contamination in many foods.
