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.China Supplier AC DC E27 Emergency Rechargeable LED Bulb LED Bulb, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Gaint Inflatable Animal Slide, 1996;White 4*8FT 18mm PVC Foam Board for Cabinets Use., 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 (Dual Function Write Ball Pen Aluminum Stylus for iPhone Xs X Se,1991).Multi Purpose Microfiber Towel Car / Home / Gift / Sport Towel. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Power Plant Circulating Water Pump & Spare Part,LED Strip Light SMD 3528 /SMD 5050/SMD 2835/SMD 5630 Rope Strip,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,Carbon Steel Equal Tee for Connection of Pipe(Gaint Inflatable Animal Slide, 1996). The soluble protein may have commercial use as gelatines,Hexagonal Glass Mix Marble Interior Decorative Mosaic Tile, peptides or amino acids production (Pool Lounger Patio Furniture Hammock Dream Chaise Lounge Chair with Canopy, 1991;Steel Stacking Restaurant Wedding Chair, 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;Rutile Anatase Titanium Dioxide for Coating and Paints., 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.Laser Cutting Machine for Sale for Die Shops From Yitai Die Making.

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%Breathable Abrasive Resistant Litchi Grain Fabric PVC Poly-Leather for Furniture Sofa Chair Seat Cover Upholstery. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
