Penyakit infeksi masih menjadi masalah yang utama diderita oleh masyarakat Indonesia. Di samping itu, banyak bakteri patogen ya ng ditemukan resisten terhadap beberapa antibiotika. Oleh karena itu, upaya-upaya untuk mendapatkan antibiotika baru perlu dilakukan secara terus-menerus. Suatu galur lokal baru Bacillus subtilis BAC4 teridentifikasi memproduksi senyawa antibiotika yang menghambat pertumbuhan Serratia marcescens ATCC27117 . Untuk memberdayakan galur tersebut, terhadap Bacillus subtilis BAC4 dilakukan mutasi dengan larutan akridin oranye dan diperoleh mutan Bacillus subtilis M10 yang memproduksi antibiotika berlebihan. Namun, kinetika produksi antibiotika oleh Bacillus subtilis M10 belum pernah dilaporkan. Penelitian ini bertujuan untuk mempelajari kinetika produksi antibiotika oleh mutan Bacillus subtilis M10 . Bacillus subtilis M10 difermentasikan ke dalam media urea-sorbitol dan diamati kemampuan produksi antibiotikanya menggunakan Serratia marcescens ATCC 2711 sebagai bakteri uji. Hasil penelitian menunjukkan bahwa mutan Bacillus subtilis M10 memproduksi antibiotika sejak jam ke 8, dan produksi optimumnya terjadi pada jam ke 14 setelah inokulasi. }, issn = {2407-5973}, pages = {185--193} doi = {10.14710/reaktor.13.3.185-193}, url = {https://ejournal.undip.ac.id/index.php/reaktor/article/view/3182} }
