Abstract
Penelitian pembentukan biosurfaktan yang dihasilkan oleh bakteri Pseudomonas aeruginosa telah dilakukan. Kemampuan bakteri dalam menghasilkan biosurfaktan diukur dengan cara mengendapkan biosurfaktan yang dihasilkan. Variasi sumber karbon dan nitrogen dilakukan untuk mendapatkan kondisi optimal dalam pembentukan biosurfaktan oleh bakteri yang digunakan. Biosurfaktan yang telah diperoleh ditentukan aktivitasnya dengan uji emulsifikasi. Hasil uji aktivitas pada variasi sumber karbon dan nitrogen menunjukkan kondisi optimum pembentukan biosurfaktan pada substrat minyak zaitun dan sumber nitrogen (NH4)2SO4 dengan menghasilkan pembentukan berupa biosurfaktan sebesar 0,026 gram per liter per jam.

Biosurfactant produced by Pseudomonas aeruginosa had been studied. The ability of bacteria to produce biosurfactant was measured by precipitating biosurfactant. Variation of carbon and nitrogen sources was performed to obtain the optimal conditions in the production of biosurfactant. Biosurfactant was determined by emulsification method. The result indicated optimum conditions on production of biosurfactant were the substrate olive oil and a source of nitrogen ((NH4)2SO4 with yield 0.026 grams per liter per hour.
