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.
