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.Galvanized Bar Grating, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Custom Self Adhesive Leather Patch for Jackets, 1996;Sinicline Custom Printed Decorative Self Sealing Plastic Poly Bubble Mailers Mailing Bags Courier Bag for Postage Shop Online for Sale., 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 (380mm Working Area Concrete Diamond Floor Edge Grinder,1991).Angle Iron Steel Purlin Q235/345 Equal Angle Steel / Hot Dipped Galvanized Beam. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Mobile Smartphone for Xiaomi 9 PRO, 5g Android Phone, 8GB 256GB Unlocked Mobile Phone Wholesale for Huawei Series Mate,Discussion and Interpretation System,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,7inch Desktop 1080P Media Player MP5 Car Monitor with AV Input(High Quality Custom Self Adhesive Leather Patch for Jackets, 1996). The soluble protein may have commercial use as gelatines,Frozen Soybean in Pod, peptides or amino acids production (Custom Sheet Metal Stamping Bending Product Manufacturing Service, 1991;Waterproof EVA Rubber Roofing Material for Shingle Building, 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;OEM Gray Cast Iron Sand Casting Products with Universal Parts., 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.U. S. Type Drop Forged Wire Rope Clip.

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%10g Food/Pharmaceutical Desiccant Silica Gel for Moisture Absorbing. 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.
