20.500.12556/DKUM-27208 Stability of proteinase from Carica papaya latex in dense gases Proteinase from Carica papaya latex was tested on its thermal stability at atmospheric pressure and in supercritical carbon dioxide, near-critical propane and dimethyl-ether. In supercritical carbon dioxide at 300 bar thermalactivation of the examined proteinase was improved in the comparison toatmospheric pressure. In propane and dimethyl-ether (300 bar) activity of the examined proteinase decreased. Influence of compressionžexpansion cycles on residual activity of the same proteinase in supercritical carbon dioxide (300 bar and 50 °C) was studied, as well. Different ways of transition from supercritical to low-pressure-state were used which affected residual activityof the proteinase.Addition of water in the system increased activity of proteinase from C. papaya, which was incubated in supercritical carbon dioxide for 24 h. Optimum amount of water was found to be between 0.5 and 0.7 g/L. chemical processing high pressure technology supercritical CO2 proteinase thermal stability pressure stability enzyme activity water content dense gases kemijska procesna tehnika visokotlačna tehnologija superkritični CO2 proteinaze termična stabilnost tlak aktivnost enzimov vsebnost vode plini visoke gostote true false false Angleški jezik Angleški jezik Neznano 2012-06-01 10:05:14 2012-06-01 10:05:14 2022-04-15 03:43:39 2019-07-10 12:12:58 2005 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 66.09-987 9162518 0896-8446 URN:SI:UM:DK:GURSR0OF http://dx.doi.org/10.1016/j.supflu.2004.05.005 1 https://dk.um.si/Dokument.php?lang=slv&id=36463 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
