Efektivitas Fraksi Metabolit Sekunder Jamur Endofit Lamun (Thalassia hemprichii) dari Kawasan Teluk Tomini Sebagai Antibakteri Jerawat

Abstract

Endophytic fungi live in their host tissues, so that endophytic fungi can produce secondary metabolites that are similar to their hosts as well. In this case, the use of endophytic fungi can reduce the exploitation of seagrass populations (Thalassia hemprichii) in Tomini Bay. This study aims to examine the effectiveness of the secondary metabolite fraction of the endophytic seagrass fungus (Thalassia hemprichii) from Tomini Bay against acne-causing bacteria. The test method used is disc diffusion method (Kirby Bauer), by measuring the inhibition zones of the ethanol fraction, ethyl acetate fraction, and the N-hexan fraction of the secondary metabolite fraction of endophytic fungi against acne-causing bacteria. The liquid-liquid partition results of the secondary metabolites of seagrass endophytic fungi from the Tomini Bay area were the N-Hexan fraction of 3.06 grams, the Chloroform fraction of 2.90 grams, and the Ethyl Acetate fraction of 1.53 grams. While the effectiveness test of the N-Hexan, Chloroform, and Ethyl Acetate fractions of secondary metabolites of endophytic seagrass microbes from the Tomini Bay area showed that the N-Hexan fraction at a concentration of 75% had greater inhibition on each of the acne-causing bacteria, namely Propionibacterium acne 17 .33 mm (strong category), Staphylococcus aureus 17.86 mm (strong category), and Staphylococcus epidermidis 16.01 mm (strong category).
