En junio de 1978, a propuesta del Dr. Masao Goto profesor de la Faculdad de Agricultura de la Universidad de Shizuoka y del Dr. Ralph E. Schwarz Jefe del proyecto argentino-alemán para el fomento de la citricultura en la provincia de Misiones-se realizó un viaje de documentación y estudio al Japón con el fin de interiorizarse de los progresos logrados en la investigación sobre la "cancrosis" de los citrus. El mismo se dividió en dos etapas. La primeira - que tuvo una duración de 14 dias - compredió una serie de visitas a todas las Estaciones Experimentales y Universidades relacionadas con la investigación de la "cancrosis" y enfermedades a virus que atacan los citrus. La segunda abarcó los 21 dias restantes y se desarrolló exclusivamente en los laboratorios a cargo del Dr. Goto en Shizuoka, donde se efectuaron trabajos experimentales con la bacteria Xanthomonas citri y sus bacteriófagos y se imtercambiaron ideas sobre los problemas básicas que habria que resolver en relación con esta enfermedad. |

The aim of this study was to analyse the effect of oil contamination and biostimulation (soil pH raise, and nitrogen, phosphate and sulphur addition) on the diversity of a bacterial community of an acidic Cambisol under Atlantic Forest. The experiment was based on the enumeration of bacterial populations and hydrocarbon degraders in microcosms through the use of conventional plating techniques and molecular fingerprinting of samples directly from the environment. PCR followed by denaturing gradient gel electrophoresis (DGGE) was used to generate microbial community fingerprints employing 16S rRNA gene as molecular marker. Biostimulation led to increases of soil pH (to 7.0) and of the levels of phosphorus and K, Ca, and Mg. Oil contamination caused an increase in soil organic carbon (170-190% higher than control soil). Total bacterial counts were stable throughout the experiment, while MPN counts of hydrocarbon degraders showed an increase in the biostimulated and oil-contaminated soil samples. Molecular fingerprinting performed with 16S rRNA gene PCR and DGGE analysis revealed stable patterns along the 360 days of experiment, showing little change in oil-contaminated microcosms after 90 days. The DGGE patterns of the biostimulated samples showed severe changes due to decreases in the number of bands as compared to the control samples as from 15 days after addition of nutrients to the soil. Results obtained in the present study indicate that the addition of inorganic compounds to soil in conjunction with oil contamination has a greater impact on the bacterial community than oil contamination only.
