Probiotic and antioxidant properties of C₃₀ carotenoid-producing Lactiplantibacillus plantarum isolated from kimchi.

ABSTRACT: This study focuses on the development of functional probiotics using caroteonid-producing lactic acid bacteria (LAB) with antioxidant properties. Thirty LAB strains were evaluated for their probiotic properties. Carotenoid biosynthesis gene cluster (crtMN operon) was detected using polymer chain reaction (PCR). The carotenoid identified as 4,4'-diaponeurosporene was analyzed via UV visible absorption spectra and HPLC. Five carotenoid-producing strains showed antioxidant activities. Lactiplantibacillus plantarum MGB0112, which showed the highest carotenoid production measuring at 470 nm of absorbance per ml of culture broth (0.014 A_470nm/ml), showed low pH (56.5%) and bile salt (97.8%) tolerance with high adhesion properties (55.1% for toluene). Furthermore, this st
