“…Así como por los metales pesados (cadmio, cobre, hierro, zinc y plomo) presentes en el petróleo (Khan et al 2013). Se ha demostrado que la fracción soluble en agua y los lixiviados de los hidrocarburos del petróleo, reducen el metabolismo y desarrollo fisiológico de las plantas tras un derrame, al inhibir la madurez fisiológica de las raíces y propiciar la reducción en la biomasa foliar (Blankenship y Larson 1978, Sadunishvili et al 2009, Hawrot-Paw y Bąkowska 2014.…”

Palabras clave: hidrocarburos, toxicidad, bioindicador, bioensayo RESUMEN Se evaluaron los efectos tóxicos que produce un suelo contaminado con petróleo fresco sobre plantas de Phaseolus vulgaris. Para ello se generó un índice absoluto de fitotoxicidad que integra siete parámetros, medidos a través de índices relativos de fitotoxicidad para las variables: altura, longitud radical, número de nódulos y biomasa seca (foliar, radical, del fruto y total). Asimismo, se calcularon los coeficientes de determinación (R 2 ). El bioensayo se realizó bajo condiciones de túnel de plástico y se evaluó los efectos tóxicos del petróleo en plantas de frijol negro (P. vulgaris L.) al cabo de 100 días. Se estableció un diseño experimental de bloques al azar en condiciones semicontroladas, con seis tratamientos con tres repeticiones por tratamiento. Las concentraciones de hidrocarburos fueron: 1500, 3000, 4500, 6000, 7500 y 9000 mg/kg de hidrocarburos totales del petróleo (HTP) y un tratamiento testigo (0 mg/kg). Al día 100, el detrimento fisiológico [emergencia (R 2 = 0.89; b = -3.427); altura (R 2 = 0.84; b = -0.0029); longitud radical (R 2 = 0.62; b = -0.001); número de nódulos (R 2 = 0.68; b = -0.0092) y biomasa total (R 2 = 0.77; b = -0.0014)] de las plantas mostró una correlación negativa con la concentración de los HTP en el suelo, con diferencias entre los tratamientos (Tukey p≤ 0.05). Al día 68 del ensayo se observó marchitez de las plantas a concentraciones mayores de 3000 mg/kg HTP.Key words: hydrocarbons, toxicity, bioindicator, bioassay ABSTRACTThe toxic effects produced by soil contaminated with fresh crude oil on Phaseolus vulgaris plants was assessed. An absolute phytotoxicity index was generated, which includes seven parameters measured by a relative phytotoxicity index for the variables: height, radicular length, number of nodules, dry mass (foliar, radical, fruit and total). Likewise, the coefficients of determination (R 2 ) were calculated. The bioassay carried out under plastic tunnel conditions and the toxic effects of crude oil in plants P. vulgaris was assessed at 100 days. A randomized complete block design was used in the bioassays under semi controlled conditions, with six treatments and three Rev. Int. Contam. Ambie.

Abstractl-Asparaginase is a therapeutically and industrially-competent enzyme, acting predominantly as an anti-neoplastic and anti-cancerous agent. The existing formulations of prokaryotic l-asparaginase are often toxic and contain l-glutaminase and urease residues, thereby increasing the purification steps. Production of l-glutaminase and urease free l-asparaginase is thus desired. In this research, bioprospecting of isolates from the less explored class Agaricomycetes was undertaken for l-asparaginase production. Plate assay (using phenol red and bromothymol blue dyes) was performed followed by estimation of l-asparaginase, l-glutaminase and urease activities by Nesslerization reaction for all the isolates. The isolate displaying the desired enzyme production was subjected to morphological, molecular identification, and phylogenetic analysis with statistical validation using Jukes-Cantor by Neighbour-joining tree of Maximum Likelihood statistical method. Among the isolates, Ganoderma australe GPC191 with significantly high zone index value (5.581 ± 0.045 at 120 h) and enzyme activity (1.57 ± 0.006 U/mL), devoid of l-glutaminase and urease activity was selected. The present study for the first-time reported G. australe as the potential source of l-glutaminase and urease-free l-asparaginase and also is one of the few studies contributing to the literature of G. australe in India. Hence, it can be postulated that it may find its future application in pharmaceutical and food industries.

“…As far as the regeneration status is concerned, the maximum tree species (64%) have been found in good regeneration category. Khan et al (2013) conducted experiments to assess the physico-chemical properties, heavy metal enrichment and fungal isolation and characterization of the top soil samples collected in-situ from aged refined kerosene contaminated as well as uncontaminated garden soil sites in Anand, Gujarat, India. In this study, it was recorded that the aged refined kerosene soil is highly contaminated with petroleum hydrocarbons which affected soil physicochemical properties, fungal population and heavy metal enrichment which are important indicators for assessing soil quality, fertility and productivity.…”
