Cold-active enzymes, sourced from cold-adapted organisms, are characterized by high catalytic efficiencies at low temperatures compared with their mesophilic counterparts, which have poor activity.
Ce2Sn1 possessed a satisfied NO removal efficiency at low temperature (160 280 °C), while over 90% NO removal efficiency maintained in the temperature range of 280 400 °C at the gas hourly space velocity (GHSV) of 50,000 h−1.
Therefore, it might explain why additional chalcopyrite increased zinc leaching efficiency at low temperature while decreased it at high temperature.
They looked for genes that code for denser hair, thicker layers of fat and blood cells that transport oxygen with increased efficiency at low temperatures.
Some psychrophilic enzymes demonstrate a higher catalytic efficiency at low temperatures, compared to the efficiency demonstrated by their meso/thermophilic homologous.
The added efficiency at low temperatures would probably not have been sufficient to pay for the ground loop, but I would have been interested to get a quote.
He also showed that a glass cover with an air gap around the absorber would not improve the efficiency at low temperatures, but when reaching high temperatures (around 220 °C), thermal insulation would be necessary.
In contrast to previous demonstrations of solid-state optical cooling from anti-Stokes emission [37 43], cooling from cross-relaxation will not lose efficiency at low temperatures because the -641 cm-1 energy gap for the process is temperature independent.
In the fish Fundulus heteroclitus, clinal variation in lactate dehydrogenase (Ldh, EC1.1.1.27) allozyme allele frequency along the environmental gradient has been found, with the LdhBb allele type having greater catalytic efficiency at low temperatures and the LdhBa allele type having greater catalytic efficiency at high temperatures [25], [26].
This suggested enhanced translation efficiency at low temperatures, which was confirmed when we observed increased resistance to translation inhibitor paromomycin.
