Chemo-enzymatic saccharification strategy of microalgae chlorella sorokiniana [PDF]

, 2020
Biofuel production using microalgae attracted much attention because it can be cultured using CO2 and sunlight. With high carbohydrate content, microalgae have the potential to be used as a fermentation feedstock for bioethanol production.

Coupling of fermentation and microfiltration for α-amylase production fromBacillus amyloliquefaciens [PDF]

FEMS Microbiology Reviews, 1994
Abstract A strain of Bacillus amyloliquefaciens secreting α-amylase was cultivated continuously in a fermentor coupled to a filtration unit. Under the tested operating conditions, the maximum flux was 91 m -2 h -1 during the first day and 61 m -2 h -1 during the 2nd day. The α-amylase retention was around 30%.

Expression ofAspergillus oryzaeα-amylase gene inSaccharomyces cerevisiae [PDF]

FEMS Microbiology Letters, 1993
Abstract A fragment containing the full length cDNA from Aspergillus oryzae α-amylase has been amplified by PCR using specific synthetic oligonucleotides. The amplified cDNA was designed to favour its expression in yeast by modifying its upstream untranslated region.

Isolation and purification of α-amylase inhibitors and their in vitro and in vivo effects on Tribolium castaneum (Herbst) and Callosobruchus maculatus (F.)

Journal of Plant Protection Research, 2020
Plant derived α-amylase inhibitors are proteinaceous molecules that regulate the enzyme activity in plants and also protect plants from insect attack. In the current study, 28 accessions of 19 plant species were screened for their α-amylase inhibitory ...

Synthesis and bioactivities evaluation of oleanolic acid oxime ester derivatives as α-glucosidase and α-amylase inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry, 2022
Different oleanolic acid (OA) oxime ester derivatives (3a-3t) were designed and synthesised to develop inhibitors against α-glucosidase and α-amylase. All the synthesised OA derivatives were evaluated against α-glucosidase and α-amylase in vitro.

Impact of calcium on salivary α-amylase activity, starch paste apparent viscosity and thickness perception [PDF]

, 2011
Thickness perception of starch-thickened products during eating has been linked to starch viscosity and salivary amylase activity. Calcium is an essential cofactor for α-amylase and there is anecdotal evidence that adding extra calcium affects ...

Expression of theStreptomyces griseusα-amylase gene inEscherichia coli [PDF]

FEMS Microbiology Letters, 1994
The amy gene of Streptomyces griseus was not expressed in Escherichia coli cells due to the lack of recognition of the amy promoter by the E. coli RNA polymerase, as confirmed by using promoter-probe vectors. The expression of the amy gene in E. coli was detected only when the promoter-less gene was placed under the control of the lacZ promoter and was

Molecular, Biochemical, and Dietary Regulation Features of α-Amylase in a Carnivorous Crustacean, the Spiny Lobster Panulirus argus. [PDF]

PLoS ONE, 2016
Alpha-amylases are ubiquitously distributed throughout microbials, plants and animals. It is widely accepted that omnivorous crustaceans have higher α-amylase activity and number of isoforms than carnivorous, but contradictory results have been obtained ...

Synthesis and Molecular Docking Studies of Alkoxy- and Imidazole-Substituted Xanthones as α-Amylase and α-Glucosidase Inhibitors

Molecules, 2023
Current antidiabetic drugs have severe side effects, which may be minimized by new selective molecules that strongly inhibit α-glucosidase and weakly inhibit α-amylase.
