“…The microbial biosurfactants can enhance bioavailability and biodegradability of low solubility compounds through reducing surface and interfacial tension at gas-liquid-solid interfaces, also have emulsifying and foaming properties [7]. In comparison with synthetic surfactants, BS are more biodegradable and less toxics, for this reason they have been applied in bioremediation processes of polluted environmental sites with heavy metals, organophosphate pesticides (lubricants, surfactant aided bioremediation) and hydrocarbon total petroleum (enhanced oil recovery, crude oil drilling) [8].…”

“…O biodiesel é um combustível derivado de óleos vegetais ou animais, normalmente composto de ésteres metílicos e ácidos graxos de cadeia longa e sua composição química e bastante variável (SCOTT et al, 2010). No processo de biodegradação, os ácidos graxos são convertidos diretamente até acetilCOA pela beta-oxidação para posterior conversão a CO2 por meio do ciclo de Krebs (BERG; TYMOCZKO;STRYER, 2006). Em comparação, os hidrocarbonetos de cadeia linear (alcanos, alcenos) primeiramente precisam ser convertidos a álcoois, aldeídos e posteriormente a ácidos graxos, para então serem convertidos pela beta-oxidação (FRITSCHE; HOFRICHTER, 2005).…”

“…Para a degradação do biodiesel pelos microorganismos deste solo, o biossurfactante microalgal fez-se necessário, a fim de dispersar as moléculas do contaminante, tornando-as biodisponíveis para o processo de degradação, o que foi observado nos ensaios adicionados de biossurfactante, que independente do contaminante apresentaram percentuais de biodegradação semelhantes. Chrzanowski et al (2012) utilizaram bactérias produtoras de ramnolipídio para biodegradação de diesel e biodiesel B20 (20% de biodiesel e 80% diesel v/v). Os resultados obtidos confirmaram que o biodiesel é o combustível de preferência biodegradado em comparação com diesel, no entanto neste estudo obteve-se uma porcentagem de degradação semelhante para os dois contaminantes.…”

“…FAME i powodują jego degradację do kwasu octowego i kwasów tłuszczowych, które rozkładane są do ditlenku węgla i wody przez enzymy w ciągu reakcji. Mikroorganizmy mają potencjalny wpływ na procesy degradacji, następującej szybciej w przypadku FAME niż paliw węglowodorowych (zawierają one węglowodory aromatyczne oraz cykliczne węglowodory alifatyczne, które nie są dobrą pożywką dla mikroorganizmów) [1,2,5,6,7,11]. Higroskopijność FAME zwiększa podatność na rozkład mikrobiologiczny.…”
