Potensi Bacillus Spp. Dalam Menghasilkan Biosurfaktan Pada Substrat Minyak Pe…

ABSTRACT Biosurfactants are extracellular macromolecules produced by microorganisms. Biosurfactants are physically environmentally friendly, and have low toxicity. This study aims to determine the potential of Bacillus spp. in producing biosurfactant compounds on lubricating oil substrates. The methods used are: drop collapse test, oil spreading technique, emulsification activity, characteriza…
