“…In the meantime, mainly based on a high level of sequence conservation of the 16S rRNA genes, several additional environmental or host-associated B. petrii isolates were described. Most isolates were found in contaminated habitats such as soil containing chlorinated benzenes [59][60][61]. However, B. petrii isolates were also found in a grass root consortium and in marine sponges [62,63].…”

Bordetella pertussis, the etiological agent of whooping cough, belongs to the bacterial pathogens first described in the so-called golden era of microbiology more than 100 years ago. In the course of the following decades, several other closely related pathogens were described which are nowadays classified in the genus Bordetella together with B. pertussis. These are the human and animal pathogens B. parapertussis, B. bronchiseptica and B. avium which are of high medical or veterinary interest, and which, together with B. pertussis, are referred to as the "classical" Bordetella species. Only in the past 15 years, several additional species were classified in the genus, frequently isolated from patients with underlying disease, animals or from the environment. Very little is known about most of these bacteria. In the present review, the current knowledge about these "new" Bordetella species is briefly summarized.

“…Las bandas IC8 e IC9 persistieron durante el tratamiento IBE, la identificación de ambos microorganismos correspondió con géneros reportados previamente como degradadoras de hidrocarburos aromáticos policíclicos (Wang et al 2007, Meenakshisundaram y Bharathiraja 2014. Entre las bandas dominantes identificadas en los suelos recién contaminados, destacan también las correspondientes a la clase Actinobacteria, al registrarse en los perfiles de forma ocasional una banda (RC22) atribuida a Nocardioides.…”

Palabras clave: actividad enzimática, DGGE, restauración de suelos, secuenciación RESUMEN Se evaluó la actividad deshidrogenasa y la dinámica de poblaciones bacterianas nativas en suelo contaminado con hidrocarburos durante su biorremediación por bioestimulación y atenuación natural. Se realizaron ensayos a escala mesocosmos, en la que se compararon dos condiciones: 1) contaminación reciente (28 días) y 2) intemperización (entre 28 a 56 días), con suelo artificialmente contaminado (30 000 mg de hidrocarburos totales de petróleo /kg suelo). Se estimó la riqueza de las comunidades bacterianas con base en los perfiles genómicos generados mediante electroforesis en gel con gradiente de desnaturalizantes (DGGE, por sus siglas en inglés). Además, se identificaron las poblaciones por secuenciación de las bandas dominantes en los perfiles de DGGE. La evolución de la biodegradación se estimó a través de la actividad deshidrogenasa durante los ensayos. El análisis molecular de los extractos de ADN, reveló una riqueza de genotipos similar en ambos tratamientos recién contaminados y una disminución importante de este parámetro por efecto de intemperismo. Los niveles máximos de actividad de la enzima se presentaron en el suelo recién contaminado-bioestimulado (3146.84 mg de iodo-nitro-formazan (INF)/g) en comparación con el suelo recién contaminado bajo atenuación natural (1160.19 µg INF/g). Para los suelos intemperizados, la actividad deshidrogenasa disminuyó en comparación con los demás tratamientos. Se determinó una comunidad bacteriana estable a lo largo del tiempo en el suelo intemperizado, mientras que la adición de nutrientes favoreció el incremento de la riqueza de genotipos tanto en los suelos recién contaminados como en los intemperizados. Se identificó la presencia de bacterias hidrocarbonoclastas (Burkholderia, Pelobacter) en todos los tiempos de muestreo en ambos tratamientos.Key words: enzymatic activity, DGGE, soil restoration, sequencing ABSTRACT Dehydrogenase activity and composition of the native microbial community were evaluated in hydrocarbon-contaminated soil during its bioremediation by biostimulation Rev.

“…Chlorinated benzenes are one of the most important groups of POPs and are widely used as intermediates in the synthesis of, inter alia, dyes, agrochemicals, rubbers, plastics, electrical goods, pesticides, pharmaceuticals and disinfectants (Meharg et al 2000;Rapp 2001;Zhang et al 2005;Ge et al 2008). However, they are extremely hazardous, occurring in a variety of environmental compartments including air, surface waters, ground water, soils, sediments and biota mainly from the discharge of industrial effluent and leachate from landfill sites (Wang & Jones 1994;Zhang et al 2005;de Araujo et al 2006;Wang et al 2007;Ge et al *Corresponding author.

The growth and antioxidant defence responses in wheat (Triticum aestivum L.) seedlings grown hydroponically with 0 (control), 10, 20, 40 and 80 mg L(1 of 1, 2, 4-trichlorobenzene (TCB) were examined to better understand plant physiological and biochemical responses to chlorinated benzenes. Fresh and dry shoot weight, chlorophyll and soluble protein contents decreased significantly with increasing TCB concentration. In contrast, the rate of production of O 2 -in the roots increased at lower TCB concentrations but decreased at higher concentrations. In addition, foliar electrolyte leakage and antioxidant defence activities increased linearly with increasing TCB concentration but were suppressed at higher concentrations in the roots. Taken together, the results support the hypothesis that antioxidant defence responses are an important component of plant responses to TCB, and oxidative damage appears to be a major factor leading to growth suppression in wheat exposed to higher TCB concentrations.
