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.Cnm Single Strand Anchor Coupler, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wisdom LED Floor Lamp, Head Lamp Fabia Mining Lamp, 1996;18X16mesh Fiberglass Window Screen Insect Screen., 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 (Newest Ultra-Long Standby Waterproof Waistband Smart Bracelet with Blood Pressure Heart Rate Monitor and Sport Supervise for for Men and Woman Watch,1991).Sterile Dsiposable Syringe for Dental 12ml. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Foldable Bed Military Cot for Camping,P5 960*960mm LED Display Screen SMD Indoor /Outdoor,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,2019 New Advertising Inflatables Air Walking Backpack Ball(Wisdom LED Floor Lamp, Head Lamp Fabia Mining Lamp, 1996). The soluble protein may have commercial use as gelatines,Side Pack Manual Gas Engine Power Brush Cutter, peptides or amino acids production (Punching Bending Welding Steel Work Fabrication, 1991;Black and White Cat Mobile/Cell Phone Cover/Case for iPhone 6/7/6plus/7plus, 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;Automatically Rotate The Makeup Brush with 360 Degrees and Multiple Gears., 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.1 Ton Chain Pulley Block with Geared Trolley.

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%Printed Wristband Cotton Wristband RFID Woven Wristband. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
