Optimization of production, purification and lyophilisation of cellobiose dehydrogenase by Sclerotium rolfsii
BACKGROUND The enzyme cellobiose dehydrogenase (CDH) can be used to oxidize lactose to lactobionic acid. As Sclerotium rolfsii is known to be a good producer of CDH, the aim of this paper was to simplify its production and secondly to systematically study its purification aiming for a high yield. Two preservation methods (freezing and freeze-drying) and the influence of several protectants were...
متن کاملPhylogenetic Placement and Morphological Characterization of Sclerotium rolfsii (Teleomorph: Athelia rolfsii) Associated with Blight Disease of Ipomoea batatas in Korea
In this study, we aimed to characterize fungal samples from necrotic lesions on collar regions observed in different sweetpotato growing regions during 2015 and 2016 in Korea. Sclerotia appeared on the root zone soil surface, and white dense mycelia were observed. At the later stages of infection, mother roots quickly rotted, and large areas of the plants were destroyed. The disease occurrence ...
متن کاملIsolation and characterization of glyoxylate dehydrogenase from the fungus Sclerotium rolfsii.
Glyoxylate dehydrogenase (glyoxylate:NAD+ oxidoreductase) was purified 600-fold in three steps from crude extracts of the fungus Sclerotium rolfsii (Corticium rolfsii Curzi). Two of the purification steps involved dye-affinity chromatography. The enzyme is a tetramer of Mr 250 000, with identical subunits of Mr 57 000. Inhibition studies suggest that there is one essential thiol group per activ...
متن کاملHost Infection beyond the Traditional Range of Sclerotium (Athelia) rolfsii with Physalis minima
Physalis minima is an herbaceous plant and inhabitant of the porous and organic matter containing soil of bunds in crop fields, wastelands, around the houses, and on the roadsides. S. rolfsii is soil borne and it can infect over 500 plant species of different families. It is of interest to study the pathogenesis of S. rolfsii on P. minima. The S. rolfsii isolated from P. minima (physr1) was cha...
متن کاملPartial Purification and Characterization of the Recombinant Benzaldehyde Dehydrogenase from Rhodococcus ruber UKMP-5M
Background: Benzaldehyde dehydrogenase (BZDH) is encoded by the xylC that catalyzes the conversion of benzaldehyde into benzoate in many pathways such as toluene degradation. Objectives: In this study, the xylC gene from Rhodococcus ruber UKMP-5M was expressed in Escherichia coli, purified, and characterized.Materials and Methods: The xylC was amplified and cloned in E. coli. The re...
