RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.


INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Wholesale Professional High Quality Cheap Women Girls Camisole Sports Top Yoga Bra, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ductile Grey Iron Casting Sand Casting, 1996;OEM Packaging Custom Luxury Vape Pen Cases for Electronic Cigarette., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (PVC Hdo Construction Formworks,1991).Screw Dosing Feeder Used for Chicken Feed Plant. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,5.5 to 7.5kw AC Frequency Inverter for Motor AC Drive,Factory Direct Disposable Delivery Surgical Drape Set/Pack with Eo Sterile,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Automatic Waste Paper Stripper(Ductile Grey Iron Casting Sand Casting, 1996). The soluble protein may have commercial use as gelatines,Halogen Operating Lamp Medical Light Surgical Lamp (L734 Mobile type), peptides or amino acids production (Mesh Stainless Steel Scourer Iron Sponge Used of Galvanised, 1991;Top Quality Sarms Yk11 Yk-11 Yk 11 Powder with CAS 1370003-76-1, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;U Truck for Partition Wall System75*50*0.5mm/Partition Drywall Steel Frame Stud., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Korea Glittery Heat Transfer Film /Vinyl for Clothes/T-Shirt Printing Cdg-16 Light Multi.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Galvanized Bar Grating. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V0) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
