Get PriceWashed starch was boiled in 500 μl of SDS loading buffer, centrifuged at 14 000 g for 15 min, and 45 μl of the supernatant was loaded onto 10% (w/v) discontinuous polyacrylamide gels. Up to 150 μg of bovine serum albumin (BSA) or the E. coli chaperone protein Cpn60 were used as control proteins in the glucan binding assays; none of these ...
Get Price2016-10-18 · Starch is a very abundant and renewable carbohydrate and is an important feedstock for industrial applications. The conventional starch liquefaction and saccharification processes are energy-intensive, complicated, and not environmentally friendly. Raw starch-digesting glucoamylases are capable of directly hydrolyzing raw starch to glucose at low temperatures, which significantly simplifies ...
Get Price2020-7-22 · The authors have fabricated novel flower-like Bi 24 O 31 Br 10 micro/nanospheres by a polyacrylamide gel method. The crystal structure, microstructure, bandgap, morphology, and optical property of the as-prepared Bi 24 O 31 Br 10 micro/nanospheres were investigated by multiple techniques. The Bi 24 O 31 Br 10 photocatalyst exhibits excellent photocatalytic performance for the …
