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.Building Material Quick Install Types of Scaffolding Couplers, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Latest New Upgraded High Security and Regular Keys Cutting Machine Sec-E9 for Automobile Industury, 1996;Hearing Aid Accessories Silicon Straight Tube Curved Tube for Rec and Mic., 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 (Strong N35 Neodymium Magnets Rare Earth Round Disc Fridge Craft,1991).Wholesale Dry Fit Plain Sport Suit Top and Pants Man′s Club T Shirt Team Shirt. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,PTFE Teflon Coated Fiberglass Fabric and Clothptfe Fiberglass Cloth,OEM High Quality Stainless Steel Ladies Anolog Wrist Watch Jewelry Diamond Watch 71092,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,Mini Succulent Planters, Cactus Pots with Wooden Cement Pot(Latest New Upgraded High Security and Regular Keys Cutting Machine Sec-E9 for Automobile Industury, 1996). The soluble protein may have commercial use as gelatines,Folded Kitchen Towel Paper Wrapping Packaging Machine, peptides or amino acids production (Cheap Topmac Brand Mobile Concrete Mixing Plant, 1991;Color Stretch Film for Pallet Wrap Use, 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;Wholesale Virgin Mink Brazilian Bundle Hair Vendor, Remy Virgin Brazilian Hair Bundle, Virgin Raw Brazilian Cuticle Aligned Hair., 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.Hemp Recycle Polyester Blenched Jersey Knit Fabric.

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%Professional High Precision SLS/SLS 3D Printing Action Figure Parts Rapid Prototyping Service. 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.
