Antimicrobial and quorum sensing inhibitory activity of epiphytic bacteria isolated from the red alga .

is a red alga that is commonly utilized in the Philippines as food and as a source of high-value natural products for industrial applications. However, there are no studies regarding the microbial community associated with and its potential applications. This study aimed to isolate and identify the epiphytic bacteria of and determine their antimicrobial and quorum sensing inhibitory (QSI) effects.

Seasonal Variation and Possible Biosynthetic Pathway of Ginsenosides in Korean Ginseng Meyer.

Whereas Korean ginseng, Meyer, is harvested in the fall, the variation of ginsenoside content in field-grown ginseng across seasonal development has never been investigated in Korea. Thus, ultra-high performance liquid chromatography (UHPLC) analysis of nine major ginsenosides, including ginsenoside Rg1, Re, Rf, Rg2, Rb1, Rc, Rb2, Rd, and Ro, in the roots of five-year-old cultivated in Bongwha, Korea in 2017 was performed. The total ginsenoside content changed as many as three times throughout the year, ranging from 1.
