Evaluation of Biosurfactant Production by Bacillus subtilis Using Glycerol

Abstract

There is a constant concern about the environmental impacts due to the increase in industrial activity. The leading causes of these impacts come from chemicals, especially organic compounds such as hydrocarbons and their derivatives, which companies often use. In search of long-term solutions, biosurfactants have gained significant prominence regarding their cost-benefit. It is favorable when compared to surfactants of petroleum origin. In order to lower costs and reduce the impacts on the environment caused by industries, this work aims to evaluate the production of biosurfactants by Bacillus subtilis using glycerol in different concentrations.
