Produção de biossurfactantes a partir de resíduos lignocelulósicos: um estudo de busca de anterioridade

Abstract

Biosurfactants molecules are synthesized from organisms such as bacteria, yeasts and fungi. The interest in these compounds has been growing in recent years due to the presentation of unique characteristics compared with chemical surfactants derived from petroleum. The biosurfactants can be employed in different sectors of the economy such as agriculture, construction, oil industry, food, pharmaceutical, among others. This paper aims to conduct a prior art search and study of biosurfactants using lignocellulosic residues as a carbon source for microorganisms producing these compounds, more specifically a search in patent filing records or even patents. For this, an analysis of patents filed in databases was carried out such as the National Institute for Industrial Property (INPI) and the World Intellectual Property Organization (WIPO). The data demonstrate a very promising area, but with little related research the use and application of lignocellulosic residues as well as demonstrating that studies are needed so that they can cover other databases and verify all patents that have arisen by chance during searches.
