A novel α‑l‑rhamnosidase with potential applications in citrus juice industry and in winemaking
(Springer, 2013-07)
The production of monoglycosylated flavonoids by α-l-rhamnosidases (EC 3.2.1.40) is an interesting development in biocatalysis. Applications of rhamnosidases in industry include removal of bitterness caused by naringin ...
Cold-active α-l-rhamnosidase from psychrotolerant bacteria isolated from a sub-Antarctic ecosystem
(Elsevier Science Inc, 2007-01-04)
Psychrotolerant bacteria obtained from sea water and alimentary tracts of benthonic organisms from the sub-Antarctic environment of Tierra del Fuego (Argentina) were screened for cold-active A-l-rhamnosidase production. ...
Dose-dependent significance of monosaccharides on intracellular α-L-rhamnosidase activity from Pseudoalteromonas sp.
(Springer, 2008-12)
Intracellular α-L-rhamnosidase (EC 3.2.1.40) from the psychrotolerant Pseudoalteromonas sp. 005NJ showed a dose-dependent inhibition for L-rhamnose (IC50 = 20 mM) and d-ribose (IC50 = 95 mM), whereas d-glucose and l-fucose ...
Synthesis of hesperetin 7-O-glucoside from flavonoids extracted from Citrus waste using both free and immobilized α-l-rhamnosidases
(Elsevier, 2015-06)
This work was aimed to design alternatives to semi-synthesize hesperetin 7-O-glucoside (HG), a low occurrence natural product, from the flavonoids hesperidin (HES) and neohesperidin (NEO) that can be extracted at large ...
Enhancement of the antioxidant activity of orange and lime juices by flavonoid enzymatic de-glycosylation
(Elsevier Science BvAmsterdamHolanda, 2013)
Production, partial purification and characterization of α-l-rhamnosidase from Penicillium ulaiense
(Springer, 2009-06)
Penicillium ulaiense is a post-harvest pathogenic fungus that attacks citrus fruits. The objective of this work was to study this microorganism as an α-l-rhamnosidase producer and to characterize it from P. ulaiense. The ...
Screening and quantification of the enzymatic deglycosylation of the plant flavonoid rutin by UV-visible spectrometry
(Elsevier, 2017-02)
Rutin is a plant flavonoid constituted by the flavonol quercetin 3-O-linked to the disaccharide rutinose (quercetin 3-O-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranoside)). The enzymatic deglycosylation of rutin is usually ...
