Susceptibility of linseed, soybean, and olive biodiesel to growth of the deteriogenic fungus Pseudallescheria boydii

Growth of Paecilomyces variotii in B0 (diesel), B100 (biodiesel) and B7 (blend), degradation and molecular detection

“…The diesel from petrol is composed by aliphatic hydrocarbons like alkanes (normal, alicyclic and cyclic), naphthenic and aromatic that can be more recalcitrant (Bücker et al, 2011;Cazarolli et al, 2014;Passman, 2013). However, some studies consider a synergic effect of biodiesel in biodegradation of diesel and biodiesel/blends due to co-metabolism (Pasqualino et al, 2006;Schleicher et al, 2009;Sorensen et al, 2011).…”

“…Many factors, such as the presence of water in the bottom of the tanks during storage, have been cited as increasing microbial growth in the systems and can lead to blocking of pipelines and filters, affecting the final quality of the fuel and corrosion of the tanks (Bento and Gaylarde, 2001;Bento et al, 2004;Bücker et al, 2011;White et al, 2011;Cazarolli et al, 2012Cazarolli et al, , 2014Zimmer et al, 2013;Passman, 2013). A concentration of only 1% water in a storage system is sufficient for the growth of aerobic and anaerobic bacteria and yeasts, as well as for the development of fungal biomass at the oil/water interface (Gaylarde et al, 1999;Chesneau, 2000;Bento and Gaylarde, 2001;Bento et al, 2004;Bücker et al, 2011;Sørensen et al, 2011;Cazarolli et al, 2012Cazarolli et al, , 2014Zimmer et al, 2013;Passman, 2013).…”

Numerous microorganisms have been isolated from fuels (Atlas, 1981;Gaylarde et al, 1999;Bento and Gaylarde, 2001;Bento et al, 2004;Bücker et al, 2011;White et al, 2011).…”

“…Biodegradability of biodiesel compared to mineral diesel it is a problem specially when occurs microbial contamination during storage which may lead to blocking of pipelines and filters, affecting the final quality of the fuel and corrosion of the tanks (Bento and Gaylarde, 2001;Bento et al, 2004Bento et al, , 2006Passman and Dobranick, 2005;Bücker et al, 2011;White et al, 2011;Cazarolli et al, 2012Cazarolli et al, , 2014Zimmer et al, 2013;Passman, 2013).…”

Discriminative potential of some PCR-based and biochemical methods at Scedosporium strains

“…Scedosporium boydii extracellular metallopeptidases can be considered even as virulence factors able to cleavage different proteinaceous sources like human serum albumin, casein, hemoglobin and IgG, but not gelatin (Da Silva et al 2006). Scedosporium boydii succeeded to growth in various biodiesels and to degrade biofuel components (Cazarolli et al 2014). Another experiments confirmed the fungus had been able to utilize tributyrin (Janda-Ulfig et al 2008).…”
