Abstract
Biosurfactants are surface-active molecules produced by various microorganisms, such as bacteria, which allow them to exhibit a variety of biological functions. The production of these secondary metabolites requires the use of substrates such as glycerol or hydrocarbons. The objective of this study is the valorization of biomolecules extracted from a bacterial strain Aeromonas salminicida isolated from the lagoon of Marchika in Nador. The production of biosurfactants was identified by screening with standard methods. The crude product was characterized by TLC, IFTIR and GC-MS. Antibacterial activity was evaluated and antioxidant activity assessment was carried out by using in vitro DPPH scavenging capacity and reducing power test. Biosurfactant screening tests revealed a reduction in surface tension and a change in emulsification index of 57%, preliminary characterization indicates that it was probably a lipopeptide biosurfactant. It has been shown that they are capable of exhibiting antimicrobial activity as well as an antioxidant effect.
