Antibacterial Activity of Sea Cucumbers Harvested from Karimunjawa
Abstract: This research was
conducted to discover bioactive compounds in sea cucumbers collected from
Karimunjawa as anti-microbial agents against several pathogenic bacteria. Five sea cucumbers species used in this study
were Teripang Gamat (Stichopus variegatus), Teripang Nanas (Stichopus
chloronotus), Teripang Getah (Bohadschia mamorata), Teripang Emas (Stichopus
herrmanni) and Teripang Babi (Bohadschia argus). Sea cucumbers extract were
subjected to a series of anti-microbial tests using Staphylococcus aureus,
Escherichia coli, Vibrio anguila, Vibrio voinivica, Bacillus subtilis, and
Pseudomonas sp. Results showed that in the preliminary study, tissue extract of
Bohadschia mamorata and Bohadschia argus were able to suppress the growth of
all tested bacteria. Further study used these two sea cucumber extracts, and
the results show that Bohadschia mamorata extract at 10 mg/ml showed the
largest antibacterial (2.18 mm) towards the pathogenic bacterium Pseudomonas
sp., while the smallest antibacterial zone (0.63 mm) was against the growth of
Bacillus subtilis. At the concentration level of 20 mg/ml Bohadschia argus
extract showed the highest antibacterial zone of 3.68 mm against Staphylococcus
aureus and the lowest inhibition zone (1.75 mm) against Pseudomonas sp.
