“…In particular, dyeing process of silk industry is necessary to increase the value of the silk fabrics. During this process, dye waste water is released as unwanted pollution source (Fabiani et al, 1996, Kim et al, 2001. According to the needs, several silkworm breeding scientists have studied to breed silkworm races, which is to cocoon with natural beautiful color.…”

A newly developed silkworm variety, GoldenSilk makes bright yellow cocoon. In this article, the basic characteristics of GoldenSilk cocoon were examined through color analysis, degumming characteristics and UV spectrophotometer. The colorant of GoldenSilk cocoon was not distributed evenly throughout the cocoon layer but existed in the outer layer of the cocoon. The colorant has not good resistance against sunlight. The degumming loss percentage of GoldenSilk cocoon was 29.2%, which is relatively higher than that of the authorized one. UV spectrophotometer showed specific absorption band around 400 to 500 nm, which is the specific yellow colorant of the GoldenSilk cocoon extracted to the degumming solution during the degumming process.

-The use of biodegradable polymers for controlled release drug delivery systems are being widely studied, because the therapeutic benefits that can be achieved. Studies have shown that exposure of diclofenac sodium (DS) in acid medium, such as occurring after oral ingestion of the drug, decreases the antiinflammatory activity. Thus, the incorporation of the drug into biopolymer particles becomes an alternative and the therapeutic effect is maintained due to the protection offered by the biomaterials. The objective of this study is to evaluate the incorporation of diclofenac sodium in particles formed from the blend of sericin and alginate subjected to gelation process with CaCl 2 . Incorporation efficiency measurement, interaction and morphology of the drug with mixtures of biopolymers were made. Also, the particle characterization was carried out to analyze the physical-chemical parameters, such as the determination of the property pH ZPC.

“…Sericin can be recovered with different techniques such as precipitation in alcohol, enzymatic hydrolysis, freeze-and tray-drying and membrane filtration (2,13,15,18,19 In literature, there seems to exist very few studies on the characterization of sericin recovered from wastewaters. To this end, this study aims to characterize the sericin protein recovered from silk wastewaters generated in cocoon cooking process of textile industry.…”
