Afifa Nafisa Windiyana. 26040118140070. Potensi Kapang Asosiasi Gorgonian
Ellisella sp. sebagai Agen Antimikroba Infeksi Kulit dan Jaringan Lunak (Agus
Sabdono dan Mada Triandala Sibero)
Penyakit infeksi kulit dan jaringan lunak telah dialami 48 dari 100 orang per
tahun selama 2005-2010 berdasarkan HealthCore Integrated Research Database
(HIRD) di Amerika. Infeksi kulit dan jaringan lunak salah satunya disebabkan oleh
mikroorganime, seperti bakteri dan jamur. Infeksi oleh mikroorganisme tersebut
dapat diobati dengan cara yang sama, yaitu menggunakan antibiotik. Namun,
antibiotik dapat menyebabkan resistensi terhadap patogen pada penggunaan jangka
panjang. Oleh karena itu, kajian senyawa antibiotik baru untuk melawan
mikroorganisme patogen bersifat resisten penting untuk dilakukan, salah satunya
dengan senyawa antimikroba dari kapang asosiasi. Kapang asosiasi diketahui
memiliki metabolit sekunder menyerupai inangnya. Gorgonian jenis Ellisella sp
diketahui menghasilkan senyawa golongan quinone dan triterpenoids yang
memiliki aktivitas antimikroba. Kapang asosiasi gorgonian Ellisella sp. diduga
mampu menghasilkan senyawa antimikroba.
. Penelitian ini bertujuan untuk mengisolasi kapang asosiasi gorgonian yang
memiliki aktivitas antimikroba melawan C. acnes, C. albicans, dan M. furfur serta
mendeteksi keberadaan gen PKS I, PKS II, dan NRPS dari kapang asosiasi
gorgonian dengan pendekatan polifasik. Metode dalam penelitian ini meliputi
sampling, isolasi dan peremajaan, uji antimikroba metode agar plug, karakterisasi
morfologi, uji biokimia berupa uji enzim dan reduksi gula, uji salinitas, identifikasi
molekuler, Biosynthetic Gene Cluster serta uji antimikroba metode Disc Diffusion.
Hasil dari penelitian ini menunjukkan bahwa pada uji antimikroba metode
agar plug isolat kapang asosiasi gorgonian Ellisella sp. BU.19.1 memiliki aktivitas
antibakteri melawan C. acnes dan M. furfur. Hasil identifikasi molekuler pada
region ITS 1 menggunakan BLAST database menunjukkan bahwa isolat BU.19.1
memiliki homologi dengan P. album sebesar 99,64%. Hasil deteksi biosynthetic
gene cluster pada isolat P. album hanya terdapat pada gen PKS-II. Hasil uji Disc
Diffusion ekstrak isolat isolat kapang P. album hanya memiliki aktivitas antibakteri
melawan C. acnes.
Kata kunci: antimikroba, kapang, gorgonian, PKS, NRPS

SUMMARY

Afifa Nafisa Windiyana. 26040118140070. Potential of Gorgonian Ellisella sp.
Associated Mold as Antimicrobial Agent Against Skin and Soft Tissue Infections
Pathogens (Agus Sabdono and Mada Triandala Sibero)
Skin and soft tissue infections have been experienced by 48 out of 100
people per year during 2005-2010 based on HealthCore Integrated Research
Database (HIRD) in USA. The skin and soft tissue infections can be caused by
microorganisms, such as bacteria and fungi. These infections are generally
treated by antibiotics. However, antibiotics can cause resistance to pathogen in
long-term use. Therefore, it is important to study new antibiotic compounds
against resistant pathogenic microorganisms, such as antimicrobial compounds
from gorgonian associated molds. Gorgonian Ellisella sp. is known to be able to
produce quinone and triterpenoids group compounds that have antimicrobial
activity. The gorgonian associated molds from Ellisella sp. are hypothesized to be
able to produce antimicrobial compounds.
This study aims to isolat gorgonian associated molds with antimicrobial
activity against C. acnes, C. albicans, dan M. furfur and to detect the presence of
PKS I, PKS II, and NRPS genes from gorgonian associated molds using a
polyphasic approach. The methods in this study include sampling, isolation and
purification, antimicrobial test using agar plug method, morphological
characterization, biochemical test in the form of enzyme and sugar reduction
tests, salinity test, molecular identification, Biosynthetic Gene Cluster and
antimicrobial test with Disc Diffusion method.
The results of this study indicate that the antimicrobial test of gorgonian
Ellisella sp. associated mold BU.19.1 has antibacterial activity against C. acnes and
M. furfur. The results of molecular identification in the ITS 1 region using the
BLAST database showed that isolat BU.19.1 has homology with P. album by
99.64%. The results of the detection of biosynthetic gene clusters in the isolat P.
album were only showed in the PKS-II gene. The results of the Disc Diffusion
method showed that the crude extracts of P. album only had antibacterial activity
against C. acnes.
