1. A procura de bactérias degradadoras de metamidofós. / Searching for methamidofos degrading bacteria.
Methamidophos is a strong acetylcholinesterase inhibitor and, therefore, a very toxic organophosphorus insecticide. This product has been widely employed for pest control in a variety of cultures, but little information is available about its biodegradation. 12 bacteria were isolated and characterized, from water and soil samples obtained from a site contami

2. Kinetics of Nitrate Utilization by Mixed Populations of Denitrifying Bacteria †
Kinetics of nitrate utilization by mixed bacterial populations from two agricultural soils and a pond sediment in Kentucky were measured by using progress curves of nitrous oxide production. Nitrous oxide production from anaerobic soil and sediment slurries containing added nitrate and acetylene exhibited first-order kinetics. Nitrate affinity (Km) for mixed

3. Kinetics of Acetate Utilization by Two Thermophilic Acetotrophic Methanogens: Methanosarcina sp. Strain CALS-1 and Methanothrix sp. Strain CALS-1
The kinetics of acetate utilization were examined for washed concentrated cell suspensions of two thermophilic acetotrophic methanogens isolated from a 58°C anaerobic digestor. Progress curves for acetate utilization by cells of Methanosarcina sp. strain CALS-1 showed that the utilization rate was concentration independent (zero order) above concentrations

4. Kinetics of Butyrate, Acetate, and Hydrogen Metabolism in a Thermophilic, Anaerobic, Butyrate-Degrading Triculture
Kinetics of butyrate, acetate, and hydrogen metabolism were determined with butyrate-limited, chemostat-grown tricultures of a thermophilic butyrate-utilizing bacterium together with Methanobacterium thermoautotrophicum and the TAM organism, a thermophilic acetate-utilizing methanogenic rod. Kinetic parameters were determined from progress curves fitted to t

5. Kinetics of Hydrogen Consumption by Rumen Fluid, Anaerobic Digestor Sludge, and Sediment †
Michaelis-Menten kinetic parameters for H2 consumption by three methanogenic habitats were determined from progress curve and initial velocity experiments. The influences of mass transfer resistance, endogenous H2 production, and growth on apparent parameter estimates were also investigated. Kinetic parameters could not be determined for undiluted rumen flui

6. Influence of pH on microbial hydrogen metabolism in diverse sedimentary ecosystems.
Hydrogen transformation kinetic parameters were measured in sediments from anaerobic systems covering a wide range of environmental pH values to assess the influence of pH on hydrogen metabolism. The concentrations of dissolved hydrogen were measured and hydrogen transformation kinetics of the sediments were monitored in the laboratory by monitoring hydrogen

7. Evidence for anaerobic syntrophic benzoate degradation threshold and isolation of the syntrophic benzoate degrader.
An anaerobic, motile, gram-negative, rod-shaped, syntrophic, benzoate-degrading bacterium, strain SB, was isolated in pure culture with crotonate as the energy source. Benzoate was degraded only in association with an H2-using bacterium. The kinetics of benzoate degradation by cell suspensions of strain SB in coculture with Desulfovibrio strain G-11 was stud
