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.New M4 Smart Bracelet Waterproof Bluetooth Step Bracelet Information Call Reminder Heart Rate Bracelet Factory Direct Gift Watches Smart Watch, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Black Polyformaldehyde Rod POM Sheet/POM Sheet/POM Rod/Acetal Rod/Delrin Sheet/Delrin Rod/Blue Delrin Sheet/Color Delrin Sheet/Colored Delrin Rod, 1996;Vp-0500 Intelligent Electric Valve Actuator Rotary Valve Motorized Actuator Low Torque Actuator for Ball Valve Butterfly Valve Quarter Turn Electric Actuator., 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 (DIN 934 Fin Hex Nut Zp M10,1991).Beauty Equipment Skin Care Machine PDT-LED Light Therapy Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Guide IR510 N1 WiFi Handheld Infrared Thermal Imaging Monocular Night Vision Camera for Hunting, Outdoor, Patrol, Search and Rescue 400X300@17μ M, 50Hz,Camera Storage Digital Hygrometer Dry Cabinet 64L Providing Xeransis Environment,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,Industrial Air Cooled Screw Water Chiller 5HP for Thermoforming Machine(Factory Black Polyformaldehyde Rod POM Sheet/POM Sheet/POM Rod/Acetal Rod/Delrin Sheet/Delrin Rod/Blue Delrin Sheet/Color Delrin Sheet/Colored Delrin Rod, 1996). The soluble protein may have commercial use as gelatines,Hamsa Design Necklaces Turkish 925 Sterling Silver Hamsa Pendant Jewelry, peptides or amino acids production (1′′ 1.5′′ 2′′ 25mm 35mm 50mm Double J Latch Hook, 1991;Japanese Taiho Brand 4D95 Orignal Crank Main Bearing Excavator Engine Piston M408h Std Size, 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;Large Span Steel Structrure for Warehouse From China., 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.New Design Steel Prefab Layer Cage Chicken House Poultry Farm.

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%Water and Oil Repellent Singeing Cement Plant Use Nomex Dust Collector Filter Bag. 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.
