“…Therefore, both aliphatic chains (hydrophobic domain) and peptide moiety (hydrophilic domain) exist in the produced biosurfactant. These pattern and bands are well similar to reports for lipopeptide biosurfactant surfactin (Al-Wahaibi et al 2014). Figure 3 represents results of surface tension measurements for different concentration of biosurfactant produced by MJ01 strain.…”

“…To infer the overall nature of chemical bonds and structural groups in the extracted biosurfactant, Fourier transform infrared spectroscopy analysis was conducted with ABB Bomem MB 100. One hundred milligrams of KBr (Merck, Germany) and 1 mg of extracted biosurfactant were completely mixed and pressed to obtain translucent pellets (Al-Wahaibi et al 2014). FTIR spectral data with resolution of 2 cm −1 were collected between 400 and 4000 cm −1 .…”

“…Sustainability is another superiority of biosurfactants to chemical surfactants, since biosurfactants can be produced from renewable feed stocks (Marchant and Banat 2012). Additionally, biosurfactants stability in harsh conditions of temperature, pH and salinity has made them preferable (Al-Wahaibi et al 2014).…”

The bacterial strain MJ01 was isolated from stock tank water of one of the Iranian south oil field production facilities. The 16S rRNA gene of isolate, MJ01, showed 99% similarity to Bacillus subtilis. The results revealed that biosurfactant produced by this strain was lipopeptide-like surfactin based on FTIR analysis. Critical micelle concentration of produced surfactin in distilled water was 0.06 g/l. Wettability study showed that at zero salinity surfactin can change original oil-wet state to water-wet state, but in seawater salinity it cannot modify the wettability significantly. To utilize this biosurfactant in ex situ MEOR process, economical and reservoir engineering technical parameters were considered to introduce a new optimization strategy using the response surface methodology. Comparing the result of this optimization strategy with the previous optimization research works was shown that significant save in use of nutrients is possible by using this medium. Furthermore, using this method leads to less formation damage due to the incompatibility of injecting fluid and formation brine, and less formation damage due to the bioplugging.

PublisherFrontiers in Microbiology About FrontiersFrontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

(um espaço) RESUMO -Biossurfactantes são moléculas constituídas de regiões apolares e polares, característica que lhes dá a capacidade de interagir com fluidos de diferentes polaridades. Tal propriedade lhes garante vasta aplicação como emulsificante, detergente e dispersante. Apresentam vantagens em relação aos surfactantes sintéticos como maior eficiência, baixa toxicidade e biodegradabilidade. A utilização de biossurfactantes em biorremediação necessita da avaliação do nível de toxicidade e eficácia destas moléculas em remover poluentes, como hidrocarbonetos. Este trabalho visa analisar a toxicidade de um biossurfactante bacteriano, além da sua capacidade em remover hidrocarbonetos de solos contaminados e comparar sua eficiência frente à surfactantes sintéticos. Resultados mostraram a baixa toxicidade do biossurfactante em sementes de alface e micro crustáceo, bem como a remoção de 91% de petróleo em areia contaminada, valor superior aos observados pelos surfactantes sintéticos analisados (SDS e Triton).(um espaço) INTRODUÇÃOSurfactantes são compostos químicos que possuem ação tensoativa. Suas moléculas são compostas por porções hidrofílicas e hidrofóbicas, as quais se distribuem na interface de fases fluidas com diferentes polaridades. Surfactantes têm vasta aplicação industrial, contando como uma de suas maiores utilizações em processos relacionados a desastres ambientes, por serem capazes de dispersar, por exemplo, óleo derramado em águas oceânicas (Pacwa-Płociniczak et al. 2011).A utilização desses dispersantes (surfactantes sintéticos) proporciona o benefício de reduzir os impactos causados pelos compostos poluentes, porém acarretam uma série de outros problemas ambientais, principalmente devido à sua toxicidade e baixa biodegradabilidade . Os biossurfactantes são moléculas de ação similar, resultado do metabolismo de microrganismos, tais como bactérias, leveduras e fungos. Os biossurfactantes se contrapõem aos surfactantes quimicamente sintetizados por apresentarem diversas vantagens em relação a estes: aceitabilidade ambiental, baixa toxicidade, biodegradabilidade em ambientes terrestres e aquáticos, entre outros (Al-Wahaibi et al. 2013).Dentro deste contexto, o objetivo deste trabalho visa avaliar o potencial de aplicação de biossurfactante bacteriano do tipo lipopeptídeo produzido pela cepa ICA56 (isolada de manguezal cearense) em ambientes contaminados com hidrocarbonetos, bem como caracterizar suas propriedades toxicológicas, tendo em vista sua aplicabilidade ambiental.Área temática: Processos Biotecnológicos 1
