“…The most used assay is the short-term lethality test on fish, but it is a time-consuming and costly assay and this has promoted the development of various short-term assays performed on bacteria, fungi, protozoa, or algae (Bellavere and Gorbi, 1981;Bitton, 1983;Blaise, 1991;Kupillas et al, 1991;Bragadin et al, 1992;Cascorbi et al, 1993;Belabed et al, 1994;Madoni et al, 1994;Schaefer et al, 1994). The response of the first bioassays was to provide a statement of the concentration of a substance which generated lethal effects (LD 50 ).…”

“…To date, toxicological experiments are oriented to the display of sublethal effects, obtained often with in vitro cultures of fish or mammalian cells, because it has been proven that these models correlate well with in vivo tests and that they can be used to predict the undesirable effects of various pollutants (Bitton, 1983;Knox et al, 1986;Borenfreund, 1986, 1991;Dierickx, 1993;Dierickx and De Vyver, 1991).…”

“…They have relatively short life-cycles, respond quickly to environmental change, are stable and inexpensive to maintain, require little space compared to benthic invertebrate and fish bioassays, and their rate of multiplication is such that a large number of cells are available for utilization in toxicity test procedures Ž . Bitton, 1983 . Although not developed specifically for the testing of freshwaters, a number of bioassays based on the inhibition by toxicants of bacterial growth have Ž been described previously Alsop et al, 1980;Trevors .…”

ResumenEl presente estudio se realizó con la finalidad de evaluar bajo condiciones de laboratorio, la influencia de tres parámetros físico-químicos sobre la actividad microbiana en un suelo agrícola medida por la cuantificación de la producción de CO 2 y actividad deshidrogenasa. Se realizaron por separado, tres ensayos para 4 porcentajes de humedad %(v/p): 5.0 %, 10.0 %, 15.0 % y 18.0 %; 4 temperaturas: 8.0 ºC, 21.0 ºC, 27.5 ºC y 37.0 ºC; y 4 valores de pH: 4.0, 6.1, 7.8 y 8.2. Cada ensayo de cuatro tratamientos y 4 repeticiones por tratamiento se condujo siguiendo los lineamientos del diseño completamente al azar (DCA). Los mayores valores de actividad microbiana [0.097 mg CO 2 ·g-1·h-1 y 173.09 µg formazán·g-1·(24h)-1] se obtuvieron a 18% de humedad, en condiciones estándares de temperatura y pH; se encontró que la temperatura de 27.5ºC era óptima para producción de CO 2 [0.140 mg CO 2 ·g-1·h-1] y 37.0 ºC para la actividad deshidrogenasa [156.78 µg formazán·g-1·(24h)-1], en condiciones estándares de humedad relativa y pH; y se estableció como pH óptimo aquel cercano a la neutralidad (7.8) [0.055 mg CO 2 ·g-1·h-1, 171.19 µg formazán·g-1·(24h)-1], en condiciones estándares de humedad relativa y temperatura. Palabras clave: Actividad microbiana, producción de CO 2 , actividad deshidrogenasa, humedad, temperatura, pH AbstractThe aim of this study was to evaluate the influence of three physical-chemical parameters on microbial activity of farm soils under controlled laboratory conditions (18% humidity, 27.5 ºC and pH 7.8). Microbial activities were quantified by carbon dioxide production and dehydrogenase activity. Three different essays for 4 moisture percentages (v/w): 5.0%, 10.0%, 15.0% and 18.0%, 4 temperatures: 8.0 °C, 21.0 ºC, 27.5 ºC and 37.0 ºC, and 4 pH values: 4.0, 6.1, 7.8 and 8.2 were evaluated. A Completely Randomized Design (CRD) was used for each essay consisting of four treatments and four replicates per treatment. The highest values on microbial activity [0.097 mg CO 2 ·g-1·h-1 and 173.09 µg formazán·g-1·(24h)-1] were obtained at 18% humidity. It was found out that a temperature of 27.5 ºC was optimum for carbon dioxide production [0.140 mg CO 2 ·g-1·h-1], and 37.0 ºC for dehydrogenase activity [156.78 µg formazán·g-1·(24h)-1]. A near to neutral pH (7.8) was established as optimum [0.055 mg CO 2 ·g-1·h-1and 171.19 µg formazán·g-1·(24h)-1]. Key words: Microbial activity, carbon dioxide production, dehydrogenase activity humidity, temperature, pH value IntroducciónExisten diversos parámetros considerados clave para determinar la calidad del suelo, aquellos de naturaleza física y físico-química (estabilidad de agregados, pH, conductividad eléctrica), química (parámetros nutricionales y fracciones de carbono), como del tipo microbiológico y bioquímico (carbono de biomasa microbiana, respiración microbiana o diversas actividades enzimáticas). El componente microbiológico puede servir como indicador del estado general del suelo, pues una buena actividad microbiana en suelo es reflejo de condiciones físi...
