Many contaminants, such as phosphatides, mucins, free fatty acids, dyes, and compounds that impact the color odor, are present in crude fats oils variable concentrations. The standard chemical refining process removes these contaminants at numerous stages, including activation, carbonization, filtration, absorption, degumming, neutralization, bleaching. While degumming is done to remove phospha...

In this study, Marseille soap and Na2CO3 are used for self-dyed silk degumming evaluated the influence of technological parameters on efficiency color intensity silk. Self-dyed results from a new dyeing method; is green without-water dye. Its mechanism based feeding silkworms with mulberry leaves supplemented by Rhodamine B dyestuff; colored was then treated at different concentrations time tre...

Alkaline polygalacturonate lyase (PGL, EC 4.2.2.2) is an enzyme used in many industries. We developed a fed-batch fermentation process that combines the enzymatic pretreatment of the carbon source with controlling the pH of the fermentative broth to enhance the PGL production from Bacillus subtilis 7-3-3 to decrease the production cost. Maintaining the fermentation broth at pH 6.5 prior to feed...

We present a silk biomaterial platform with highly tunable mechanical and degradation properties for engineering and regeneration of soft tissues such as, skin, adipose, and neural tissue, with elasticity properties in the kilopascal range. Lyophilized silk sponges were prepared under different process conditions and the effect of silk molecular weight, concentration and crystallinity on 3D sca...

Out of various no edible oil resources, jatropha curcas oil is considered as a promising alternate fuel for CI engines. The present study describes the process used for production of degummed jatropha oil (DGJO) and jatropha methyl ester (JBD) The important fuel properties of DGJO and JBD were determined and compared with fossil diesel and jatropha oil. The degumming and trans esterification pr...

The paper presents the synthesis and performance of an immobilized phospholipase A1 with practical application for oil degumming. The polyvinyl alcohol (PVA) had a number of properties indicating this polymer as a good enzyme carrier. The combination with alginate made a macro-porous structure, evidenced by SEM analyses. When the process time in boric acid solution was 30 minutes, the results r...
