“…Biosurfactants are a natural class of surface active molecules with diverse structures that are produced by different microorganisms, including bacteria, yeasts and filamentous fungi (SOUZA et al, 2017). In literature consulted (BICCA et al, 1999;NITSCHKE and PASTORE, 2003;BARROS et al, 2008;ABDEL-MAWGOUD et al, 2008;GASPARIN et al, 2012;DOS SANTOS and JÚNIOR, 2011;DECESARO et al, 2013;AL-WAHAIBI et al, 2014;DE FRANÇA et al, 2014;ALMEIDA et al, 2015;MORAIS et al, 2015;AGUIAR et al, 2015, ZHANG, 2016 a high incidence of studies reporting the production of microbial biosurfactants of bacterial origin was found, and the pathogenic nature of some producers restricts the wide application of these compounds.…”
