Effect of Sterilization by Dry Heat or Autoclaving on Bacterial Penetration through Berea Sandstone.
A study was undertaken to determine why bacteria could penetrate lengths of consolidated sandstone (Berea) faster when the sandstone was sterilized by autoclaving than when dry heat (150 degrees C, 3 h) was used. Changes in permeability, porosity, and pore entrance size of the rock as a result of autoclaving were not sufficient to explain the differences in penetration times observed, but elect...
متن کاملSterilization by dry heat.
The advantages and disadvantages of three forms of dry heat sterilization are discussed. In addition a fourth method, consisting of heating by infrared rays in vacuo, is described. This method is particularly suitable for instruments used in the operating theatre, since it can replace an autoclave where a supply of steam is not available. Recommended times and temperatures for dry heat steriliz...
متن کاملSeismoelectric measurements on artifical porous media and Berea sandstone
Seismic to electromagnetic wave conversion has been proposed as a possible exploration method. We present laboratory measurements of the conversion of an acoustic wave into electric potential, which occurs at a fluid/porous-medium interface. The conversion is measured for artificial porous media and Berea sandstone. Recorded electric potentials are smaller for largegrain samples. We also show v...

15 صفحه اولThe effect of glucose and heat sterilization on bacterial assimilation of cystine.
The various permutations of the Maillard aminosugar "browning" reaction (Maillard, 1912) have attracted the attention of microbiologists only within recent years, although food technologists have long been concerned with this class of reactions (Kline, 1950). Although Lewis (1930) warned of the effects of such reactions in bacteriologic culture media, their potential significance in many types ...
