Enzymatic bioelectrocatalysis relies on immobilizing oxidoreductases electrode surfaces, leading to different applications, such as biosensors [...]

objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...

background & aim: when the level of free radicals is increased and also when both the enzymatic systems and low molecular antioxidants are not sufficient to protect the organism, it seems necessary to get antioxidants from external sources. this study aimed to evaluate the antioxidant potential of different parts of catharantus roseus experimental: the antioxidant potential of ethanol extra...

crude enzyme (beta-galactosidase) extract (cee) was produced by lactobacillus ssp. bulgaricus chr hansen lb-12 and was applied in sterile milk which had been processed through ultra high temperature method (uht milk), for hydrolyzing lactose. lactosehydrolyzed milk was also produced by a pure and commercially available betagalactosidase (maxilact). optimum quantities of cee and maxilact enz...

the effect of enzymatic treatment time of microbial transglutaminase (mtgase) on the characteristics of whey protein isolate (wpi) films was investigated. results shown that the properties of mtgase-treated films were affected by increasing the enzymatic treatment time. enzymatic treatment at lower incubation time, i.e. for 1 h, significantly resulted in higher values of tensile strength (ts) a...

objective(s):hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. in the present study, we evaluated the effect of ethanolic extract of ensete superbum seeds (esse) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. materials and methods:glucose, hba1c, total protein, albumin, renal function mark...

enzymatic deinking of xerox printed papers by commercial cellulase from aspergillus niger fungi was investigated. enzymatic treatment was done under constant condition of 0.1 percent enzyme based on oven-dried weight of pulp (102 unit per 100 gram oven-dried pulp), 15 min. treatment time, in four ph levels as 4, 5.7, 8 and 9. then, the effect of ph variation on the appearance and strength prope...
