Inactivation of Enzymes in an Aqueous Solution by Micro Dioxide - bubbles of Supercritical Carbon

Enzyme solutiens of glucoamylase, acid protease, alkaline protease and lipase were treated with micro-bubbles otsupercritical carbon dioxide (SC CO,) fed from a cylindrical filter nozzle. The microbllbbles of SC C02 could increase the CO, concentration in the sample solution from O.4 to O.92molfl at 25 MPa and 350C, and hence could improye the eMciency of inactiyation by about 3 times compared ...

SupercriticalCarbon Dioxide Micro-Bubble

Advances in the apptication of supercritical (SC), gaseous (G), and ]iquid (LQ) C02 hayc been made regarding the interaction with biological materials or organisms. There are sevcral reports dealing with the influences of SC, G, and LQ C02 on proteins,i'2) amino acids,i) enzymes,3'S) and microbial eells.b'7) Kamihara et aL have described that wet cells (water content of 70-90g,h) of baker's yea...

Reactions in supercritical carbon dioxide

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...
