Abstract

Sea cucumber is well known as medicinal food that has antimicrobial property. The purpose of the study was to determine the potency of symbiotic bacteria from the sea cucumber gut as an antibacterial against MDR pathogens, and its application as hand sanitizer products. In this study, two species of sea cucumber, namely Holothuria atra and Holothuria leucospilota, were examined. Through bacterial isolation, 42 bacteria were obtained from the sea cucumber’s gut. The isolate were screened in order to get the ability against the anti-multi-drug resistant (MDR) i.e. MRSA and ESBL bacteria. Among all isolates, 11 candidates exhibited significant activity against MDR microbe from the MethicillinResistant Staphylococcus aureus (MRSA) while 15 isolates showed significant activity against ExtendedSpectrum β Lactamase (ESBL) MDR microbe. The chosen isolate were identified biochemically and molecularly by DNA extraction, amplification, and sequencing. The antiseptic gel was prepared and then challenged by MRSA and ESBL bacteria at 100, 250, 500, and 1000 µg per disk. Five microbe samples (TB-7, TB-18, TB12, TH-20 and TH-15) showed synergic interaction to each other, which means it can be a bacterial consortium. Anti-microbial activity in ethyl acetate fraction against MRSA was found with 1.7±0.60 mm and 2.8±0.49 mm inhibitory zone diameter at concentration of 500 µg per disk and 1,000 µg g per disk, respectively. The study concluded that symbiotic bacteria found in the gut of sea cucumbers were from genus Bacillus. These bacteria produce anti-microbial substances against MDR strain microbes potentially as hand sanitizer products.
