Recent Patents on the Industrial Application of Biosurfactants

Biosurfactants are natural bioactive compounds produced from fungi, bacteria and plants. These molecules have several properties that enable them to be involved in various industrial applications. The surface-active properties of biosurfactants allow their use in various sectors, such as agriculture, health, cosmetics, bioremediation/ petroleum, mining, and bioprocess.

The objective of this study was to analyze the patents deposited in intellectual property databases for applications of biosurfactants in the areas of agriculture, health, cosmetics, bioremediation/petroleum, mining, and bioprocesses, with the research period consisting of the last six years.

This study targeted the use of biosurfactants in various industrial sectors. The patent search was carried out using the Google Patents platform, a platform that is commonly used for this purpose and freely accessible.

During the search for patents related to applications of biosurfactants in industry filed in the last 6 years, results were found to be distributed in the following areas: agriculture (70), cosmetics (2311), bioremediation/petroleum (179), health (1794), mining (5), and bioprocess (133). Six patents were selected from each area, except for health and mining, for which the search resulted in only 5 and 4 patents, respectively, to be discussed and provide information on the biotechnological applications of biosurfactants in the industry.

The present study showed a wide area of application of biosurfactants in industry. The interest in the inclusion of biosurfactants in the industry is directly related to the need for more sustainable solutions to solve real market problems. The cosmetics sector presented the most patents that employ the use of biosurfactants.
