Real Silk Degumming Wastewater Remediation: Simple Applicable Recovery of Sericin Micro and Nano powders

Effect of Strongly Alkaline Electrolyzed Water on Silk Degumming and the Physical Properties of the Fibroin Fiber

Strongly alkaline electrolyzed water (SAEW) was prepared by electrolysis of tap water in a laboratory-made water electrolyzer. The pH of stored SAEW was stable for more than one month. The hardness of the electrolyzed water was 30% lower and the Na(+) concentration was 18% higher than those of the tap water. Silkworm cocoon shells were boiled in pH 11.50 SAEW at a ratio of 1∶40∼80 (W/V) for 20 ...

Production of silk sericin/silk fibroin blend nanofibers

Silk sericin (SS)/silk fibroin (SF) blend nanofibers have been produced by electrospinning in a binary SS/SF trifluoroacetic acid (TFA) solution system, which was prepared by mixing 20 wt.% SS TFA solution and 10 wt.% SF TFA solution to give different compositions. The diameters of the SS/SF nanofibers ranged from 33 to 837 nm, and they showed a round cross section. The surface of the SS/SF nan...

Preparation of elastic silk sericin hydrogel.

This paper reports a preparation method for silk sericin hydrogel using the Sericin-hope silkworm, whose cocoons consist almost exclusively of sericin. Sericin solution, prepared from Sericin-hope cocoons, contains intact sericin and forms elastic hydrogels with the addition of ethanol. The sericin hydrogel can be prepared without crosslinking by chemicals or irradiation and might be usable as ...

Silk sericin and its applications: A review

Silk consists of two types of proteins, silk fibroin and sericin. Sericin contributes about 20-30 per cent of total cocoon weight. It is characterized by its high content of serine and 18 amino acids, including essential amino acids. There are different methods of isolation of sericin from silk thread. Solubility, molecular weight, and gelling properties of sericin depend on the method of isola...
