Investigation on Cyclodextrin Production with Cyclodextrin Glucanotransferase from Bacillus megaterium
The process of producing cyclodextrins from starch with cyclodextrin glucanotransferase from Bacillus megaterium has been studied. The effect of starch and enzyme concentrations was evaluated using optimal composite designs and the response surface methodology. Mathematical models describing the process in two overlapping areas of variation of the independent variables were developed. The model...
متن کاملGenetic and rat toxicity studies of cyclodextrin glucanotransferase
INTRODUCTION Microbiologically derived cyclodextrin glucanotransferase (CGTase) is used commercially as a processing agent in manufacture of food, pharmaceuticals, and cosmetics. Its toxic potential was evaluated in anticipation of use in the production of alpha-glycosyl isoquercitrin, a water-soluble form of quercetin. METHODS Following OECD guidelines, CGTase, produced by Bacillus pseudalca...
متن کاملMicrowave Accelerated Transglycosylation of Rutin by Cyclodextrin Glucanotransferase from Bacillus sp. SK13.002
Rutin was subjected to intermolecular transglycosylation assisted with microwave irradiation using cyclodextrin glucanotransferase (CGTase) produced from Bacillus sp. SK13.002. Compared with the conventional enzymatic method for rutin transglycosylation (without microwave irradiation), microwave-assisted reaction (MAR) was much faster and thus more efficient. While the conventional reaction too...
متن کاملCrystallization and preliminary X-ray diffraction studies of Tyr167His mutant α-cyclodextrin glucanotransferase from Bacillus macerans.
Improving the specificity of α-cyclodextrin glucanotransferase is a significant issue in the field of α-cyclodextrin production. In this study, a constructed Y167H mutant α-cyclodextrin glucanotransferase with enhanced α-cyclodextrin specificity was successfully expressed and purified. Single crystals were grown using PEG 4000 as a precipitating agent by the hanging-drop vapour-diffusion method...
متن کاملBrevibacterium marinum sp. nov., isolated from seawater.
A novel yellow-pigmented actinobacterium was isolated from seawater collected from Hwasun Beach in Jeju, Republic of Korea. A comparative analysis of the 16S rRNA gene sequence indicated that the organism, designated HFW-26(T), was closely related to members of the genus Brevibacterium. As found for other species of the genus Brevibacterium, strain HFW-26(T) possessed meso-diaminopimelic acid a...
