“…Sphingomonas utilize PAHs as a sole source of carbon and energy. Sphingomonas have catechol 2,3-dioxygenase activity for phenanthrene and anthracene [46]. These bacteria were presented in all four samples in this study.…”

“…The production of biosufactants solubilize and facilitate the penetration of hydrocarbons through the hydrophilic cell wall. Furthermore, this genus also contains hydrocarbon-degrading enzymes on the cytoplasmic membrane [46]. Mycobacterium has also been found in a PAH-contaminated soil from a natural gas plant, and pyrene was the only source of carbon and energy [47].…”

Pollution of freshwater ecosystems from polycyclic aromatic hydrocarbons (PAHs) is a global concern. The US Environmental Protection Agency (EPA) has included the PAHs pyrene, phenanthrene, and naphthalene among the 16 priority compounds of special concern for their toxicological effects. The aim of this study was to adapt and characterize a microbial consortium from ore waste with the potential to remove these three PAHs from water. This microbial consortium was exposed to the target PAHs at levels of 5, 10, 20, 50, and 100 mg L−1 for 14 days. PAH bioremoval was measured using the analytical technique of solid phase microextraction, followed by gas chromatography mass spectrometry (SPME-GC/MS). The results revealed that up to 90% of the target PAHs can be removed from water after 14 days at a concentration level of 100 mg L−1. The predominant group of microorganisms identified at the phylum taxonomic level were the Proteobacteria, while the Actinobacteria were the predominant subgroup. The removal of phenanthrene, naphthalene, and pyrene predominantly occurred in specimens of genera Stenotrophomonas, Williamsia, and Chitinophagaceae, respectively. This study demonstrates that the use of specific microorganisms is an alternative method of reducing PAH levels in water.

“…El aceite residual automotriz (ARA), una mezcla de hidrocarburos (HICO) alifáticos, aromáticos y trazas de metales pesados, 1,2 que de acuerdo con la Ley General de Equilibrio Ecológico y Protección Ambiental (LGEEPA) se considera residuo peligroso para el ambiente. 3 El ARA derramado en suelo forma una capa impermeable, bloqueando la difusión de O2 (oxigeno) y agua, 4 causando un desequilibrio en la relación C:N (carbono/nitrógeno), que inhibe la actividad de la microbiota heterotrófica aerobia autóctona (MHAA) que oxida la materia orgánica (MO), y como consecuencia reduce la productividad agricola. 5,6 Al respecto la NOM-138-SEMARNAT /SSA-2012, 7 establece un límite máximo permisible de 4400 ppm de HICO, fraccionada en: 200 fracción ligera, 1200 mediana 1200 y 3000 ppm pesada.…”

En suelo 75000 ppm de aceite residual automotriz (ARA), que es una mezcla de hidrocarburos (HICO) que acorde con la NOM-138-SEMARNAT/SSA1-2012 (NOM-138), sobrepasa el límite máximo permisible de 4400 ppm, que impide la mineralización de la materia orgánica y le causa perdida de fertilidad. Una alternativa de solución para este problema en suelo es la bioestimulación (BIS) con un detergente (DEGE) que emulsifique el ARA, en secuencia un solución mineral (SOMI) rica en nutrientes esenciales, seguida de Phaseolus vulgaris y Vicia sativa potenciados con Micromonospora echinospora y Penicillium chrysogenum como abono verde (AVE) y lombricomposta (LOCO) que asegura una efectiva y continua mineralización del ARA. El objetivo de esta investigación fue analizar la BIS de un suelo contaminado por 75000 ppm de ARA hasta un valor inferior al máximo permisible por la NOM-138. En ese sentido a la par de la BIS se cuantificó la microbiota de la mineralización del ARA y por cromatografía de gases se determinó ARA la concentración inicial y final en el suelo, los datos numéricos se analizaron por ANOVA/Tukey. Los resultados indicaron que la BIS del suelo impactado por 75000 ppm de ARA, lo disminuyó hasta 1532 ppm, lo que demostró que la compleja de HICO del ARA fue necesario un DEGE, una SOMI, P. vulgaris y LOCO que con compuestos orgánicos e inorgánicos de NH4 + , NO3-, PO4-3 y K2O, que indujeron a la microbiota a oxidar el ARA, avalado por el incremento de la población involucrada que causo cambios en el pH y la cromatografía de gases que probo la desaparición de los alifáticos y aromáticos a un valor de 1532 ppm, inferior al máximo aceptado por la NOM-138. Se concluye que la BIS fue útil para remediar el suelo impactado por una relativa alta concentración de ARA.

“…To date, several studies have treated a large amount and different kind of biotechnologically relevant molecules produced by bacteria isolated from abiotic and biotic matrices in cold polar environments [4,8]. The main Antarctic areas on which bioprospecting research was focused are represented by water, soil and marine sediments nearby the most active research stations, where several authors have detected a greater bacterial diversity, attributed to the influence of human activities [9][10][11]. Therefore, studies are mainly focused in the areas of King George Island (Arctowski Base), Livingston Island (Byers Peninsula) and Budd Shore (Casey Station) [12].…”

The application of an ever-increasing number of methodological approaches and tools is positively contributing to the development and yield of bioprospecting procedures. In this context, cold-adapted bacteria from polar environments are becoming more and more intriguing as valuable sources of novel biomolecules, with peculiar properties to be exploited in a number of biotechnological fields. This review aims at highlighting the biotechnological potentialities of bacteria from Arctic and Antarctic habitats, both biotic and abiotic. In addition to cold-enzymes, which have been intensively analysed, relevance is given to recent advances in the search for less investigated biomolecules, such as biosurfactants, exopolysaccharides and antibiotics.
