“…amicalis strain DRM 190-07 was isolated from the soil contaminated with diesel oil collected near the REPLAN petroleum refinery in Campinas, São Paulo, Brazil. This strain was originally identified by morphological and biochemical analysis as Planococcus citreus strain CCT 4018 (Jacobucci et al 2001;Jacobucci et al 2009). The isolate has been subsequently reclassified as G. amicalis based on 16S rDNA sequence analysis.…”

“…Jacobucci et al (2009) describe a strain of P. agglomeras isolated from soil contaminated with oil able to grow and produce BS using kerosene as sole carbon source, what bioremediate proposed as candidate for hydrocarbon contaminated sites, it is possible that the strains isolated in this study are able to grow in hydrocarbons as sole carbon source for their ability also shown in emulsification. It described that the BS produced by Pantoea sp., Is of glycolipid type (Dewart et al, 2006, Gomes de Almeida et al, 2015, so presumably the BS produced by native strains are the glycolipids type.…”

“…Jacobucci et al (2009) describen una cepa de P. agglomeras aislada de suelos contaminado con aceite capaz de crecer y producir BS empleando keroseno como única fuente de carbono, lo que la proponen como candidata para biorremediar sitios contaminados con hidrocarburos, es posible que las cepas aisladas en este estudio sean capaces de crecer en hidrocarburos como única fuente de carbono también por su habilidad mostrada en la emulsificación. Se ha descrito que el BS producido por Pantoea sp., es de tipo glicolipido (Dewart et al, 2006;Gomes de Almeida et al, 2015), por lo que presumiblemente el BS producido por las cepas nativa sean del tipo glicolipidos.…”

Pantoea agglomerans es una bacteria benéfica en diversas plantas ya que promueve el crecimiento vegetal, aunado a esto solo algunas cepas pueden producir biosurfactantes, estos biosurfactantes son capaces de causar hemolisis en agar sangre, formar espuma, dispersar el aceite, disminuir la tensión superficial por el colapso de la gota, emulsificar compuestos hidrófobos entre otros, estas características los hacen interesantes dado que tienen diversas aplicaciones biotecnológicas, en las que destacan, la recuperación de crudo, en el área médica, en la industria de los alimentos y en agropecuarias, en esta última pueden ser usados para el control de hongos fitopatógenos, los biosurfactantes tienen diversas ventajas, son compatibles con el ambiente, toleran altas concentraciones de NaCl, pH, temperatura y son biodegradables, son producidos por hongos, levaduras y bacterias, es por ello que se aislaron e identificaron bacterias capaces de producir biosurfactantes en la rizosfera de los pastos Tanzania (Panicum maximun) y Llanero (Andropogon gaynus Kunth) en el rancho Tecomate en el estado de Guerrero, de las muestras se obtuvo una carga bacteriana en rizosfera y raíz en P. maximun de 1 x 103 a 10 x 104 y en A. gaynus Kunth de 5 x 103 a 21 x 104 UFC/g respectivamente, de estas solo 28 cepas fueron capaces de producir hemolisis, espuma en PPGAS y colapso de la gota, además de presentar capacidad de emulsificar diésel, gasolina, aceite vegetal y petróleo, solo cinco de las cepas de P. maximun y ocho de A. gaynus Kunth se identificaron a nivel microbiológico reportando la presencia por vez primera de Pantoea aglomerans en asociación a la rizosfera y en raíz de los pastos, estos datos sirven de base para generar estudios sobre su ecología y aplicación biológica para incrementar la producción económica de pastos en el estado de Guerrero.

“…At optimal concentration, both microbial metabolites showed simultaneous action on the availability/hydrolysis of fats, and the authors concluded that there is potential to treat wastewater from a poultry slaughterhouse and there will be no need for a flotation phase. Jacobucci et al (2009) observed, by COD reduction, the application of two bacterial species (Pantoea agglomerans and Planococcus citreus) that are biosurfactant producers and of a biosurfactant produced by them, in a greasy effluent that comes from a soap and margarine industry. The effluent presented 4,400 mg L -1 COD and 70 to 76% of removals that were obtained from COD with an application of bacterial strains and biosurfactants after 24-contact hours with the effluent.…”

The use of a biosurfactant surfactin produced by Bacillus subtilis LB5a in cassava growth medium (cassava wastewater) was evaluated to treat anaerobically, the effluent from a poultry slaughterhouse. During the effluent pretreatment, effects of surfactin concentration factors were evaluated, considering the ones which were superior and below its critical micelle concentration (CMC = 28 mg L -1 ): 6, 13, 27, 31, 48, 73 and 56 mg L -1 and temperature (25, 30, 42.5, 55 and 60°C) up to 6 h, using the rotational central composite design. During anaerobic treatment, flasks were filled with anaerobic sludge as inoculum and a pretreated effluent for 4.5 h in its different concentrations of surfactin. Reactors were connected to eudiometers under static system at 34°C. During the pretreatment phase, there was a direct ratio between temperature and surfactin concentrations according to the increase of organic matter solubilization, measured by soluble chemical oxygen demand (SCOD). These results have shown surfactin applicability produced by B. subtilis LB5a during the anaerobic treatment of effluent from a poultry slaughterhouse; as for all treatments, there was no inhibition of microbial consortium of the anaerobic sludge. SCOD removal was above 80%, while oil and greases removal was above 70%, plus a propitious specific methane yield.
