Penisilin adalah antibiotika yang pertama kali ditemukan dan digunakan untuk pengobatan infeksi bakteri. Sejak ditemukan penisilin sebagai antibiotika oleh Alexander Fleming pada tahun 1928, banyak usaha dilakukan untuk meningkatkan produktivitas Penicillium chrysogenum. Pemuliaan galur untuk meningkatkan produksi penisilin dapat menggunakan mutasi acak secara fisika dan kimia. Pada penelitian ini, radiasi sinar ultraviolet digunakan untuk mendapatkan mutan P. chrysogenum. Produksi penisilin ditentukan menggunakan HPLC dan produktivitas mutan dibandingkan dengan induk P. chrysogenum. Mutan M12 menghasilkan penisilin 1,23 kali lebih banyak dibandingkan dengan induk P. chrysogenum.Kata kunci: Penisilin, Penicillium chrysogenum, ultraviolet, mutan, radiasi ABSTRACTPenicillin is the first antibiotic discovered and used for treatment of bacterial infections. Since the discovery of penicillin as antibiotic by Alexander Fleming in 1928, much effort has been invested to improve productivity of Penicillium chrysogenum. Strain improvement to increase the penicillin production can be carried out by physical and chemical random mutation. In this research, ultraviolet irradiation was used to obtain P. chrysogenum mutant. Penicillin production was determined by using HPLC and productivity of P. chrysogenum mutants was compared to the wild type. Mutant M12 produced 1.23 fold higher penicillin than the wild type did.Keywords: Penicillin, Penicillium chrysogenum, ultraviolet, mutant, radiation

Isolation, identification, and evaluation of antimicrobial activity of active compound produced by marine actinomycetes isolate A32 has been conducted. Production of active compound using isolate A32 was conducted by glucose, yeast, peptone medium. The fermentation was carried out at 30ºC for 5 days. The broth of supernatant was extracted using ethyl acetate. Purification of active compound used column chromatography and eluted stepwise with the chloroform and methanol solvent. Antimicrobial activity was monitored by the agar diffusion, and microbial test used as followed Escherichia coli ATCC 25922, Staphylococcus aureus ATCC25923, Bacillus subtilis ATCC 66923, and Candida albican BIOMCC00122. Results of isolation and purification of active compound produced by isolate A32 showed that this compound has a molecular weight of 503.1 g/mol with molecular formula C26H37N3O7. Analysis of spectrum using 1HNMR and COSY, this compound was suspected as Madumycin II. The antibacterial activity assay showed that this active compound was able to inhibit to the growth of Staphylococcus aureus ATCC25923 and Candida albican BIOMCC00122.
