Acerola's pectin methylesterase: studies of heat inactivation
(Elsevier B.V., 2000-12-01)
The effect of temperature on the activity of acerola's pectin methylesterase (PME) was studied to determine its heat-inactivation. The acerola's pectin methylesterase (PME; EC: 3.1.1.11) is very stable at 50 degrees C (10% ...
Evaluation of gene expression SAP5, LIP9, and PLB2 of candida albicans biofilms after photodynamic inactivation
(Springer, 2015-07-01)
With the increasing number of strains of Candida ssp. resistant to antifungal agents, the accomplishment of researches that evaluate the effects of new therapeutic methods, like photodynamic inactivation (PDI), becomes ...
2,2'azo-bis-amidinopropane as a radical source for lipid peroxidation and enzyme inactivation studies
(Informa Healthcare, 1991)
1. 2,2'Azo-bis-amidinopropane (ABAP) thermal decomposition produces free radicals that initiate the lipid peroxidation of erythrocyte ghost membranes. 2. Addition of 6-n-propyl-2-thiouracil decreases the rate of the process, ...
Inactivation kinetics of peroxidase and polyphenol oxidase in peach juice treated with gaseous ozone
(Wiley Blackwell Publishing, Inc, 2018-02)
The effectiveness of gaseous ozone for inactivating peroxidase (POD) and polyphenoloxidase (PPO) in peach juice was investigated. The suitability of first-order and Weibull models to describe inactivation kinetics was also ...
Production of xylo-oligosaccharides by immobilized-stabilized derivatives of endo-xylanase from Streptomyces halstedii
(2013-03-01)
An endoxylanase from Streptomyces halstedii was stabilized by multipoint covalent immobilization on glyoxyl-agarose supports. The immobilized enzyme derivatives preserved 65% of the catalytic activity corresponding to the ...
Inactivation of vesicular stomatitis virus through inhibition of membrane fusion by chemical modification of the viral glycoprotein
(2007-01-01)
Membrane fusion is an essential step in the entry of enveloped viruses into their host cells triggered by conformational changes in viral glycoproteins. We have demonstrated previously that modification of vesicular ...
Development of enzymic time-temperature integrators with rapid detection for evaluation of continuous HTST pasteurization processes
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The assessment of the thermal process impact in terms of food safety and quality is of great importance for process evaluation and design. This can be accomplished from the analysis of the residence time and temperature ...
Comparative Effects Of High Isostatic Pressure And Thermal Processing On The Inactivation Of Rhizomucor Miehei Protease
(ELSEVIER SCIENCE BVAMSTERDAM, 2016)
Influence Of High Pressure Homogenization On Commercial Protease From Rhizomucor Miehei: Effects On Proteolytic And Milk-clotting Activities
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
Influence of Different Substrates on the Production of a Mutant Thermostable Glucoamylase in Submerged Fermentation
(Humana Press Inc, 2011-01-01)
Three mutations, Ser54 -> Pro, Thr314 -> Ala, and His415 -> Tyr, were identified in Aspergillus awamori glucoamylase gene expressed by Saccharomyces cerevisiae. The mutant glucoamylase (GA) was substantially more thermostable ...
