DETERMINATION OF THE ANTIMICROBIAL EFFECTS OF MICRO- AND MACRO-ALGES ON THE PATHOGENIC MICRO-ORGANISMS IN AQUACULTURE
Project no. 1155 · Status: Kapanmış · 2017
Summary
ABSTRACT Pathogenic microorganisms are the causative agents of various diseases in humans, animals and plants. With the discovery of the use of antibiotics in the treatment of bacterial diseases in the early twentieth century, people's health conditions improved but drug-resistant strains developed. With the discovery of new bioactive compounds with potential antimicrobial value in the oceans, it has been found that sesquiterpenes, chlorotanenes, bromoditerpenes, halogenated furanones and lectins contained in various algae are new therapeutic agents that affect a wide range of pathogenic microorganisms. Many researchers extracted bioactive compounds from algae sources using different solvents such as acetone, ethyl alcohol, chloroform, ethyl, methanol, acetic acid and benzene. The selected extraction method and solvent type are the most important parameters that play a role in the difference in the degree of antimicrobial activity. Within the scope of this project, a) micro- and macroalgal extracts which have the potential to be used in the treatment of pathogenic microorganisms encountered in aquaculture were prepared, b) antimicrobial effects of algal extracts on pathogenic microorganisms were determined and c) bioactive compounds responsible for the effect of algal extracts were determined.
