(57) Synthetic sugar sulfuric acid peptides of a new class with a glycan sulfate and tyrosine residues of one or more bound to the [summary] peptide a (GSP), glycans, including Lewis group or Lewis group The is preferred. GSP has a O- the glycans comprising the GalNAc 尾1,6 binding ...
Presently, an acid/sugar stream from sulfuric acid hydrolysis of cellulose is treated with lime to precipitate the acid as gypsum. This technique not only consumes acid and lime, but also generates waste gypsum that is sent to a landfill. An ion exclusion process to perform acid/sugar ...
The aqueous feed solution, usually containing 10 wt.% sucrose and 10 wt.% sulfuric acid, was generally introduced into the system at a rate of roughly 2 L/hr. Approximately 4 L/hr of water was used to elute materials through the separation system. After optimization, the separation system ...
Next, 100 μL of One-step Ultra TMB ELISA substrate (Thermo Fisher Scientific, 34028) was added to each well and incubated for 15 min at RT; 100 μL of 2 M sulfuric acid was then added to stop the reaction, and absorbance at 450 nm was detected using a plate reader ...
Disclosed is a process for manufacturing an sugar ester product of a sugar and a fatty acid. First, a fatty acid and methyl or ethyl alcohol is reacted in the presence of sulfuric acid catalyst to produce a fatty acid ester and water. The sulfuric acid catalyst is neutralized with a metal...
The paddy straw was pretreated with 1% (v/v) of sulfuric acid at 95 掳C for 60 minutes followed by enzymatic hydrolysis. Optimization of enzymatic hydrolysis is desirable to achieve high yield of sugar from solid residues with high cellulose content. The optimization has been carried out by ...
The first method is a colorimetric method for the determination of total carbohydrates with a phenol/sulfuric acid reagent in combination with paper chromatography (Dubois et al., 1956). The other method is based on the gas chromatography–mass spectrometry (GC–MS) analysis of derivatized sugar ...
Sulfuric acid immobilized on silica: An efficient reusable catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives. Tetrahedron Lett. 2006, 47, 6987-6991; (b) Roy, B.; Mukhopadhyay, B. Sulfuric acid immobilized on silica: An excellent catalyst for Fischer ...
The most effective means for removal of the acid, which was commonly known at that time, was lime precipitation; however, the cost associated with attendant sulfuric acid and calcium oxide consumption was found to be economically unattractive. Also, the additional cost of disposal of the ...
Combined sugar yields for dilute sulfuric acid pretreatment of corn stover followed by enzymatic hydrolysis of the remaining solids A number of previous studies determined dilute acid pretreatment conditions that maximize xylose yields from pretreatment or glucose yields from subsequent...
