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.One Step HBV 5 in 1 Rapid Test, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Insulating Glass Rubber Assembly Table (Insulating Glass Machine) Rubber Assembly Tool, 1996;2019 Summer Fresh Landscaping Turf Lawn., 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 (Pipe Sheet Laser Cutter with Tube Cutting,1991).Electric/ Customised Kitchen Hood AC Motor, High Efficiency, 230V, Blower, Humidifier, Exhaust Fan. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Construction Material Prepainted Aluminum Steel Coils, Color Coated Aluminum Coils,Supply Christmas Lace Gold Silver Offray Silk Ribbon,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,Products Genuine Leather En345-1 Steel Toe Cap Leather Safety Boots(Insulating Glass Rubber Assembly Table (Insulating Glass Machine) Rubber Assembly Tool, 1996). The soluble protein may have commercial use as gelatines,Toast Stamp Loaf Bread Tin Pan (ZMA), peptides or amino acids production (Cheap Price 30 50 80 100 150 200 Watt SMD Motion Sensor Outdoor Solar LED Street Light, 1991;ISO9001 & Ce Certificated Superfine Cocoa Cake Powder Grinder Mill, 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;Wiskind Hot-Rolled Low Cost Commercial Steel Structure Greenhouse., 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.Baking Soda 99.8% Min Sodium Bicarbonate.

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%150mm Interior Decorative WPC Ceiling Tiles PVC Wall Panels. 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.
