dc.description	It was intended to see growth of bacterial load of contaminated samples, based on adaptation to different concentrations of phenol. Were followed in the middle mineralized concentrations (200 to10000mg/L), and variations of inoculum. Demonstrated changes in bacterial growth, increased burden found in soil, with phase adjustment on the second day and growth phase on the third day, most clearly in 200 and 500mg/L, decreasing with increasing concentration. Comparing variations in the inoculums (directly adapted and pre-enrichment), the samples can be applied to direct high load (soil), the pre-enrichment is not practical for bacterial stress, can be used and adapted to 500mg/L with no problems. In ringing on agar (mineralized and nutritious), there was growth up to 1000mg/ L, making it clear toal low detailed study biochemical characterization. It is important to purify waste water from different sources to find bacteria that resist high concentrations of phenol and allow effective ness in bioprocesses, knowing preadaptation behaviors, such as study time and appropriate treatment for the preparation of inoculum.	en-US
dc.description	En el presente trabajo se determinó la carga bacteriana de muestras de agua y suelo contaminadas con diferentes concentraciones de fenol. Se hizo seguimiento en medio mineralizado con concentraciones de 200 a 10000mg/L y variaciones de inoculo. Se evidenciaron cambios en crecimiento bacteriano, encontrándose mayor carga en suelo con fase de adaptación al segundo día y fase de crecimiento en cuarto día. Comparando variaciones del inoculo (directa, adaptado y preenriquecimiento) el directo puede aplicarse para muestras de carga alta (suelo); el preenriquecimiento no es práctico por el estrés bacteriano y adaptado permite ser usado hasta 500mg/L sin problemas. En repiques sobre agares (mineralizados y nutritivo) hubo crecimiento hasta 1000mg/L. Es importante para depurar aguas residuales, encontrar bacterias de diferentes fuentes que resistan altas concentraciones de fenol y permitan efectividad en bioprocesos al estudiar comportamientos de pre adaptación, tiempos y tratamientos adecuados para la preparación del inóculo.	es-ES
