Laguncularia racemosa (Combretaceae) y bacterias terrestres asociadas medio siglo después de la contaminación crónica por hidrocarburos

The evaluation of the impact of oil on the soil-root interaction of the white mangrove plant, Laguncularia racemosa is essential to identify changes in microbial activity and biotechnological potential for remediation contaminated histosols. The objective was to evaluate the spatial distribution of...

The objective was to evaluate the spatial distribution of total petroleum hydrocarbons (THP) in organic soil, the population density of plant growth promoting bacteria, also in microbial respiration in the rhizoplane (RI), in the rhizosphere (RZ) and in non-rhizospheric soil (NRS) of L. racemosa. An area of 8 000 m2 of an affected histosol was evaluated, during 1967 and 1968, by chronic oil spill and drilling mud from the La Venta 248 oil well. Fifteen trees of this species were selected to obtain samples of the RI, RZ and NRS. The TPH were extracted in soxhlet with dichloromethane for eight hours and quantified by gravimetry. The average amount extracted from TPH allowed the differentiation of four soils (S) from the evaluated area, the average values were for S1: 1 797 mg kg-1 (not contaminated for Mexican regulations) and three contaminated soils, the values are S2: 3 294, S3: 5 249, and S4: 10 389 mg kg-1. The results show statistical differences (Duncan, P ≤ 0.05) between means of the evaluated variables. The greatest accumulation of TPH was 22 962 mg kg-1, it was extracted from the NRS in S4. The highest densities of N-fixing bacteria, P solubilizers, Azospirillum and Azotobacter were biostimulated by the presence of high levels of THP in the soil, however microbial respiration was inhibited. The results suggest that L. racemosa is sustainable in soils with weathering oil, and is a biostimulator of microbial activity for natural attenuation.Universidad de Costa Rica2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdf0034-7744https://www.redalyc.org/articulo.oa?id=44965908008https://www.redalyc.org/journal/449/44965908008/https://www.redalyc.org/journal/449/44965908008/html/https://www.redalyc.org/journal/449/44965908008/44965908008.epubhttps://www.redalyc.org/journal/449/44965908008/movilDOI 10.15517/RBT.V67I6.35861Revista de Biología Tropical (Costa Rica) Num.6 Vol.67reponame:Redalyc-COLPOSinstname:Colegio de Postgraduadosinstacron:COLPOSeshttp://www.redalyc.org/revista.oa?id=449Revista de Biología Tropicalinfo:eu-repo/semantics/openAccessoai:redalyc.org:449659080082025-03-05T19:14:26Z
