The characterization and bioactive properties of carotenoid lutein produced by Gordonia rubripertincta GH-1 from Pixian Douban, a Chinese traditional condiment, were investigated. The carotenoid pigment was identified through various spectroscopic and analytical techniques, and it was found to have strong antioxidant capacity and a protective effect on zebrafish eye cells. The results suggest that carotenoid lutein from G. rubripertincta GH-1 could be used as a potential source of natural antioxidants or functional additives for the food and pharmaceutical industries.
The characterization and bioactive properties of carotenoid produced by Gordonia rubripertincta GH-1 originating from Pixian Douban (PXDB), the Chinese traditional condiment, was investigated. The produced and purified yellow pigment was characterized by ultraviolet-visible spectroscopy (UV-Vis), Fourier transformed infrared (FTIR), nuclear magnetic resonance (NMR), and high-resolution mass spectrometry (HRMS), and was identified as carotenoid lutein. Additionally, the bioactive activity of lutein from G. rubripertincta GH-1 was evaluated by measuring the free radical scavenging capacity in vitro and feeding zebrafish lutein through aqueous solution. The results showed that the carotenoid lutein had strong antioxidant capacity and a protective effect on zebrafish eye cells, which could inhibit the apoptosis of eye cells in a concentration dependent manner. The results suggested that carotenoid lutein from G. rubripertincta GH-1 could be utilized as a potential source of natural antioxidants or functional additives for food/pharmaceutical industries.
