  • Laboratory test system to measure microbial respiration rate

    This study reports a sensible, accurate and economic method for continuous measuring microbial respiration. The measuring principle is an open system, with a continuous air-flow through. Evolved CO2 is absorbed and precipitated as carbonate by a Ba(OH)2 solution, causing a stoichiometrical decrease in ionic strength of the solution and in electrical conductivity. ...

  • Lichens show that fungi can acclimate their respiration to seasonal changes in temperature

    Five species of lichens, the majority members of a soil-crust community (Cladonia convoluta, Diploschistes muscorum, Fulgensia fulgens, Lecanora muralis, Squamarina lentigera) showed seasonal changes of temperature sensitivity of their dark respiration (DR) to such an extent that several substantially met the definition of full acclimation, i.e. near identical DR under different nocturnal ...

  • Response of soil microbial activity to temperature, moisture, and litter leaching on a wetland transect during seasonal refilling

    In nutrient impoverished landscapes in southwest Australia, terrestrial litter appears to be important in phosphorus (P) turnover and in the gradual accumulation of P in wetland systems. Little is known about the fate of P leached from litter during the wet season and the associated effects of soil microclimate on microbial activity. The effects of temperature, moisture, and litter leaching on ...

  • Improving bioremediation

    Sustainability is becoming a benchmark for the quality of companies who offer remediation solutions, the technologies that they develop and offer commercially, as well as the entire projects where they are used. It is, in essence, not something that can be simply ignored in the months and years ahead if standards are to continue to improve, says Tom Hayes of Ecologia. The sustainability ...

  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...
