The capacity of the strains to grow at high temperature (trial 4) was tested in duplicate in 4-day long experiments, in batch regime using 40 mL, 20 mm in diameter glass tubes.
Even at 50 °C enzyme shows 90% of its optimum activity at 40 °C but enzyme inactivation takes place abruptly at higher temperatures tested which infers it as mildly thermostable in nature.
This method was developed using crude ore and liquid samples obtained from the GeoBiotics temperature controlled mesophilic heap operation at the Agnes Gold Mine in Barberton, South Africa, and the high temperature test columns at SGS Lakefield Research, Johannesburg, South Africa.
Lastly, a full-field measurement technique (Digital Image Correlation) has been used at high temperature to test the model's ability to qualitatively and quantitatively predict the surface strains distribution of TP composites in high gradient structures.
The capacity of the selected strains to grow at high temperature was tested.
Some dispersants may decompose at high temperatures, therefore, tests under reservoir conditions such as SDS and filtration methods can be considered as promising tools for choosing the best dispersant before injecting into a well.
Orientation controlled Cu bicrystals with dispersed B2O3 particles, where B2O3 behaves liquid-like at high temperature, were tensile tested at elevated temperatures.
Scratch tests are performed at run at room temperature, due to the risk of degradation of the indenter diamond tip at high temperature and added test complexity.
It is difficult to predict RDT high temperature stability since evaluations of similar immunochromatographic assays, based on detection of Ag and Ab using precoated proteins and migration on nitrocellulose, have given variable results from robustness at high temperature to complete test failure.
In this study, a significant negative impact on survival was detected at the highest temperature tested of 32.6 °C, but not at any other temperature tested, though there appeared to be reduced survival at 29.4 °C.
