Effect of bacterial β-amylase and fungal α-amylase on the digestibility and structural characteristics of potato and arrowroot starches
(2016-01-01)
Retrograded and debranched starch, known as resistant starch type 3 (RS3), is resistant to digestive enzymes and exhibits a behavior similar to that of dietary fibers. In this study, the effect of β- and α-amylase on the ...
A critical assessment of a viscometric assay for measuring Saccharomycopsis fibuligera α-amylase activity on gelatinised cassava starch
(Elsevier Science Inc, 2002-02)
A viscometric technique for measuring Saccharomycopsis fibuligera DSM-70554 α-amylase on gelatinised cassava starch aqueous solutions was assessed. The selected conditions for working over a reliable viscosity measurement ...
Influence of molecular structure on the susceptibility of starch to α-amylase
(2019-06-01)
The effect of the molecular structure of sweet potato (SPS), cassava (CAS)and high amylose maize (HAS)starches on the susceptibility to fungal and maltogenic α-amylases was investigated. The logarithm of the slope (LOS)and ...
The dormancy-breaking stimuli "chilling, hypoxia and cyanamide exposure" up-regulate the expression of α-amylase genes in grapevine buds
(2014)
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
α-Amylase inhibitors : a review of raw material and isolated compounds from plant source
(Faculty of Pharmacy & Pharmaceutical Sciences, 2013)
Control of amylase production and growth characteristics of Aspergillus ochraceus
(2002-01-01)
The growth and the extracellular amylase production by Aspergillus ochraceus were studied in a stationary culture medium. Maximum growth rate of this fungus was found after 5 days of incubation at 30° C, but maximum amylase ...
α-Amylase Aspergillus oryzae Immobilized on Modified Expanded Perlite
(De Gruyter, 2014-10)
The α-amylase from Aspergillus oryzae was immobilized covalently onto expanded perlite (EP) and modified EP by treatment with TiO2 (EP-TiO2), dye HE3B (EP-HE3B) polyethylene terephthalate (PET)-hydrazide (EP-PET) and ...
Determination of amylase activity in cotyledons of Phaseolus vulgaris L. cv. carioca
(Brazilian Archives of Biology and Technology, 1998-06-01)
Determination of α- and β-amylase activity in the extracts of cotyledons of Phaseolus vulgaris L. cv. cariocawas done using selective inactivation of α-amylase by lowering the pH of the incubation medium or by the use of ...
Relationship between carbon source, production and pattern action of α-amilase from Rhizopus sp
(1997-12-01)
This paper discusses the inducer effect of corn soluble starch and the individual components (amylose and amylopectin) from corn and potatoes starch for α-amylase production by a strain of Rhizopus sp. The following ...
Modification and characterization of natural aluminosilicates, expanded perlite, and its application to immobilise α – amylase from A. oryzae
(Elsevier Science, 2016-05)
The aim of this study was to modify natural silicoaluminates as expanded perlite (EP) through simple and inexpensive treatments in order to get a greater reactivity of surface and immobilise α-amylase from A. oryzae by ...
