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.Automatic Frozen Fried Food French Fries Potato Chips Packaging Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Water Chiller Air Cooled Chiller Industrial Chiller for Sale, 1996;Leather Swivel Task Chair Boss Modern Office Racing Gaming Chair., 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 (High Precision Tungsten Carbide Machine Customized Cutting Tool,1991).I7s Tws in Ear Stereo Bluetooth Earphone Headset with Battery Charging Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Maleic Anhydride CAS 108-31-6,2000mj Q Switched for Pigment Removal with Ce Certification,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,Fashion Home Decoration Paper 3D Wall Christmas Come From Manufactured(Water Chiller Air Cooled Chiller Industrial Chiller for Sale, 1996). The soluble protein may have commercial use as gelatines,Cow Dung Chicken Manure Organic Fertilizer Making Machine, peptides or amino acids production (marble Makeup Brush Set for Travel in 20PCS, 1991;Swimming Pool Water Disinfect Ozone Generator, 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;20kv 50kVA High Voltage Dry Type Power Supply Transformer., 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.Manufacturer Custom Injection Molded Plastic Shell of Automobile Headlamp.

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%PRO-Installer Fiber Optic Termination Kit Lk-6016. 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.
