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.150*100mm Rearview Mirror Anti Fog Film Rain Proof Oval Film for SUV Car Mirror, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Germany Wool Felt Fedora Trilby Mountain Alpine Hat with Rope and Feather, 1996;Cleaning Lint Free Microfiber Mop., 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 (L2.072.324 Pm74 Sm74 XL75 Hdm Bellows Feeder Dust Cover Length 80mm,1991).Herbs and Spices Solar Drier Mobile Solar Flower Vegetable Fruit Drying Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,LED Emergency Exit Light Rechargeable 220V,Ss 5 Micron Sinter Powder Liquid Cartridge Filter Stainless Steel Metal Water Filter with M20 M30 M40 Thread Connector,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,Firefighting Equipment Aluminum Rescue Tripod with Winch 30m(Germany Wool Felt Fedora Trilby Mountain Alpine Hat with Rope and Feather, 1996). The soluble protein may have commercial use as gelatines,Rotor Disc Brake Pad Repair Kit for Wva 29087/29202/29253/29279, peptides or amino acids production (Non-Deformation Kitchen Cleaning Sponge Mesh Sponge Scourer, 1991;Automatic Controller Carbon Steel Sheet Pipe China CNC Plasma Cutter, 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;Cjx2-F (LC1-F) AC Magnetic Contactor., 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.30W Portable Vehicle Bomb Moving Signal Jammer for GSM/2g/3G/4G Cellular GPS WiFi Signal.

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%Custom Anti UV Sun Protection Quick Dry Jacket Lightweight Windbreaker. 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.
