Aims The current study aimed to investigate the ability of lactic acid bacteria (LABs) in removing four polycyclic aromatic hydrocarbons (PAHs) namely, benzo(a)pyrene (BaP), benz(a)anthracene (BaA), chrysene (Chr) and benzo(b)fluoranthene (BbF) from contaminated phosphate buffer saline (PBS). Method and Results The effect of initial PAH concentrations (5, 10, 15, 20 μg ml−1), bacterial population (107, 108, 109, 1010 CFU per ml) and pH (3, 5, 7) was studied to evaluate bacterial binding ability. All the tested bacteria could remove BaA, Chr, BbF and BaP from phosphate buffer solution and in almost all assays, removing of PAHs was as follows: BaP>Chr>BaA>BaF. Bifidobacterium lactis BB‐12 had the lowest binding rate for all four PAHs, while the highest binding ability was related to Lactobacillus acidophilus LA‐5. Moreover, cell viability was not required for the binding ability and even acid‐treated, heat‐treated and ultrasonic‐treated bacterial cells showed more binding ability. The results showed that the bacteria–PAH complex was irreversible after washing with PBS. Conclusions The removal of PAHs was significantly related to pH of media, strains of bacteria, type and concentration of PAHs Significance and Impact of the Study This study has been focused on the reduction of polycyclic aromatic hydrocarbons using LABs and probiotics. Our results showed that not only live strains but also inactivated tested strains are able to remove PAHs from aqueous media, presenting new methods to diminish the amount of these contaminants in foods. Furthermore, the results of this study can be used in future research on evaluating the effects of oral administration of probiotic supplements and even dead probiotic strains on reducing PAHs in humans.

“…Los microorganismos que intervienen en este proceso son principalmente bacterias y en menor proporción, hongos nativos y algas. La tasa de degradación microbiana está condicionada por la capacidad de adaptación de los microorganismos nativos a las nuevas condiciones edáficas, la disponibilidad de nutrientes, el contenido de oxígeno, la temperatura, la conductividad eléctrica (CE) y el pH (Abed et al 2015, Bansal y Kim 2015, Gupta et al 2015. La bioestimulación por otro lado, consiste en la incorporación de nutrientes y aceptores de electrones para incrementar la actividad microbiana, con el objeto de acelerar la tasa de biodegradación si las condiciones ambientales son favorables (Tyagi et al 2011, Wu et al 2016.…”

Palabras clave: biodegradación, antraceno, fenantreno, microorganismos, suelos, HAP RESUMENLos hidrocarburos aromáticos policíclicos (HAP) son compuestos orgánicos que pueden persistir en el ambiente debido a su hidrofobicidad y a su baja solubilidad en agua, lo que representa un riesgo de ingresar a la cadena trófica. Ciertos microorganismos edáficos son potencialmente capaces de degradarlos. La incorporación de nutrientes puede acelerar la tasa de biodegradación si las condiciones del suelo son favorables. Los objetivos del presente trabajo fueron estudiar el efecto disipador de los microorganismos edáficos nativos en un suelo contaminado artificialmente con dos HAP (antraceno o fenantreno), además de evaluar el efecto en la disponibilidad de macro y micro nutrientes. Adicionalmente, se estudió la influencia de la estructura química del contaminante en el proceso de biorremediación. Se realizó un ensayo de incubación con un suelo hapludol típico contaminado artificialmente con antraceno o con fenantreno. La actividad microbiana se estimó en forma indirecta través de la producción de CO2. La presencia de antraceno o de fenantreno no afectó la actividad microbiana edáfica inicial. Se observó un incremento en la emisión total de CO2 en los suelos contaminados comparado con los suelos sin contaminar debido a la degradación de los contaminantes. Al término de 60 días se analizaron los suelos por cromatografía gaseosa con detector de espectrometría de masas. Según los tratamientos, la concentración de antraceno y de fenantreno disminuyó un 75 -77 % o un 89 -91 %, respectivamente. Lo que indica la capacidad de los microorganismos nativos edáficos para degradar rápidamente ambos contaminantes. La disipación del fenantreno fue mayor que la correspondiente al antraceno, lo que fue atribuido a su diferente biodisponibilidad en el suelo. No se observaron diferencias significativas entre tratamientos con y sin nutrientes, por lo que se concluye que la disponibilidad de éstos no fue limitante para la actividad catabólica de los microorganismos edáficos.

“…Some PAHs are listed on the U.S. Environmental Protection Agency (EPA) priority pollutant list due to their toxic and mutagenic effects [5]. Probable human health effects of PAHs include, but are not limited to, skin damage, DNA damage, birth defects, and cancer development [6,7].…”

Leaching behavior of organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) can be altered in the presence of organic amendments through enhanced sorption of PAHs to the amended soil. The aim of the present study was to investigate the influence of biochar in two forms (i.e., crushed and pulverized), and granular activated carbon on immobilization and leaching behavior of selected PAHs from contaminated soil into water using the column leaching test. The influence of biochar particle size on leaching behavior of PAHs in biochar-amended soil was also evaluated for the first time in this study. Results showed relatively high initial concentrations of naphthalene, fluorene, and pyrene for unamended column (B1). Strong sorption of all PAHs to soil was observed in this study. At the end of the experiment less than one percent of the solid phase content of the sum of PAHs was released into water in columns B3 and B4. Change in pH due to the application of organic amendments did not affect PAH leaching results. The addition of pulverized biochar and granular activated carbon to soil remarkably reduced mobilization and leaching of the studied PAHs in most cases; however, higher molecular weight PAHs (i.e., pyrene, benzo(b)fluoranthene, and indeno(1,2,3-cd)) were mobilized in the presence of crushed biochar in soil. The controlling role of biochar particle size on mobilization and release of PAHs in soil was observed. The application of pulverized biochar and activated carbon increased colloid content of the column effluents while reducing their dissolved organic carbon (DOC) content, suggesting a more significant role of colloid-facilitated transport than DOC-associated transport of PAHs in their leaching from carbon-amended soils, particularly for higher molecular weight PAHs. Based on the obtained results, pulverized biochar and granular activated carbon demonstrated promising and comparable performance in immobilizing PAHs in soil and reducing their leaching from soil into water through enhanced sorption of PAH compounds, which is markedly favorable in terms of soil remediation.
