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.

Consolidated bioprocessing of starchy substrates into ethanol by industrial Saccharomyces cerevisiae strains secreting fungal amylases [PDF]

, 2015
The development of a yeast strain that converts raw starch to ethanol in one step (called Consolidated Bioprocessing, CBP) could significantly reduce the commercial costs of starch-based bioethanol. An efficient amylolytic Saccharomyces cerevisiae strain

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 ...

The Amylases of Insects [PDF]

International Journal of Insect Science, 2018
Alpha-amylases are major digestive enzymes that act in the first step of maltopolysaccharide digestion. In insects, these enzymes have long been studied for applied as well as purely scientific purposes. In many species, amylases are produced by multiple gene copies. Rare species are devoid of Amy gene.

A thin layer chromatographic comparison of raw and soluble starch hydrolysis patterns of some α-amylases from Bacillus sp. isolated in Serbia [PDF]

Journal of the Serbian Chemical Society, 2014
Several natural isolates of Bacillus strains namely 5B, 12B, 16B, 18 and 24B were grown on two different temperatures in submerged fermentation for the raw-starch-digesting a-amylases production. All strains except Bacillus sp.

Utilisation of wheat bran as a substrate for bioethanol production using recombinant cellulases and amylolytic yeast [PDF]

, 2015
Wheat bran, generated from the milling of wheat, represents a promising feedstock for the production of bioethanol. This substrate consists of three main components: starch, hemicellulose and cellulose.

Production of bioethanol from multiple waste streams of rice milling [PDF]

, 2017
This work describes the feasibility of using rice milling by-products as feedstock for bioethanol. Starch-rich residues (rice bran, broken, unripe and discolored rice) were individually fermented (20% w/v) through Consolidated Bioprocessing by two ...

Non-linear correlation between amylase day 2 to day 1 ratio and incidence of severe acute pancreatitis

Frontiers in Cellular and Infection Microbiology, 2022
BackgroundThis study aimed to assess whether the amylase day 2/amylase day 1 ratio was associated with severe acute pancreatitis (SAP).MethodsWe retrospectively enrolled 464 patients with acute pancreatitis. Serum amylase was measured on admission (day 1)
