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.
