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.Men′s Black and Grey Stripe Bamboo Dress Sock, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (CNC Brass Parts Manufacturing Nickel Plated Finish Brass Machining Part, 1996;China Customized High Quality Stainless Steel Precision Motorcycle Parts /Accessory Sample., 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 (Hot Sale Mobile Phone Shop Display Furniture Interior Design,1991).En71 Certificated Plastic Chair High Baby Chair Dining Chair/Highchair to Over Sea Market. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pet Dryer Machine /Pet Dryer Box/ Pet Hair Dryer,Rubber Seal for Crank Box of Hks Warp Knitting Machine,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,OSD Language Wireless Smart LED TV 32 Inch Android OS 4.4 System RJ45(CNC Brass Parts Manufacturing Nickel Plated Finish Brass Machining Part, 1996). The soluble protein may have commercial use as gelatines,Industrial High  Temperature  Resistant Smooth Flat Wire Power Cable, peptides or amino acids production (New Fashion TPU Mobile Cover Case for Huawei, Leather Phone Case for Huawei Mate 20, 1991;Customized HSS M100*3.0 Large Thread Cutting Tools Cutter Used for CNC Milling Machine, 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;Extruded Polystyrene Foam Board Custom Edges S/L., 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.Hite 200tc Capsule Hotel Motel Bedding Plain Bed Sheet Sets.

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%Europe Style Wholesale Custom PVC Double Bathroom Cabinet Vanity Mirror Cabinet. 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.
