Influence of Different Substrates on the Production of a Mutant Thermostable Glucoamylase in Submerged Fermentation
(Humana Press Inc, 2011-01-01)
Three mutations, Ser54 -> Pro, Thr314 -> Ala, and His415 -> Tyr, were identified in Aspergillus awamori glucoamylase gene expressed by Saccharomyces cerevisiae. The mutant glucoamylase (GA) was substantially more thermostable ...
Gelatinization properties of native starches and their Naegeli dextrins
(Springer, 2011-12-01)
Cassava, potato, sweet potato, and Peruvian carrot starches were hydrolyzed with 15% v/v sulfuric acid solution for up to 30 days. Naegeli dextrins obtained from 1, 3, 6, 12, and 30 days were evaluated using differential ...

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 ...
Microstructural changes of potato cells and starch granules heated in oil
(ELSEVIER SCIENCE BV, 2001)
A method that mimics the frying operation was implemented to observe microstructural changes in potato cells and starch. Isolated cells were obtained by successive treatments of potato tissue with acid and alkali solutions. ...
Effect of photocatalytic pretreatment of potato starch for bioethanol production using Saccharomyces cerevisiae during simultaneous saccharification-fermentation (SSF)
(DYNA, 2019-02-19)
In this study, the effect of photocatalytic (PC) pretreatment of potato starch with TiO2 during the gelatinization (GE) stage of a simultaneous saccharification-fermentation (SSF) process for bioethanol production was ...
Production of cyclodextrins by CGTase from Bacillus clausii using different starches as substrates
(Humana Press Inc, 2014)
Preparation and properties of phosphate starches from tuberous roots
(2021-07-31)
The diversification of raw materials in the starch industries is a current strategy. However, the production of native starches does not meet market demand, and it is essential to expand the knowledge about chemical ...
Influence of nitrogen fertilization on the characteristics of potato starch
(2018-03-01)
This study evaluated the effect of nitrogen fertilization rates on the characteristics of potato starch. The experimental design was randomized block with four replications. The treatments were composed of four rates of N ...
In vitro Digestibility and Glycemic Response of Potato Starch is Related to Granule Size and Degree of Gelatinization
(WILEY, 2009)
Starch granule microstructure affects the digestion of starch and its nutritional impact; however, the exact relationship between both factors is not clear. This study reports quantitative relationships between granule ...
