Biosurfactants Production by Fermentation Process Using Waste as Substrate – A Patent Search Report

Biosurfactants are active compounds capable of reducing surface tensions produced by microorganisms, having low toxicity and high biodegradability with possible production from renewable sources. This work aims at presenting a patents search on the biosurfactants production through fermentation, using waste as substrate. The methodology consisted of searching keywords and their blending, using the database of Derwent innovation. The search returned 15 patent registrations filed in the last 8 years. Of the 15, 10 orders are active. After analysis, 3 of the 10 selected patents showed strong adherence to the subject, describing the use of waste as substrates to produce more economical biosurfactants.
