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.2019 Panfeng Color Painting Three Flavor Soft Ice Cream Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Alu 2319 Slimline 12mm Wide Recessed Profile, 1996;High Quality Garden Green House/Glass Green House/ Conservatory/Sun Room/Gazebo., 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 (Custom Size Christmas Gift Personalized Watch Boxes for Men,1991).12 Strands UHMWPE Braide Rope Synthetic Winch Rope Mooring Rope. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,8p8c Mini RJ45 Female Jack Module Connector RJ45 Connector,Manufacture Hot Rolled Galvanized/Black U Shaped Iron Steel Channel Upn/Upe Good Price High Quality,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,New Arrival Educational Wooden Toddler Walking Toys for Push Along W16e115(Alu 2319 Slimline 12mm Wide Recessed Profile, 1996). The soluble protein may have commercial use as gelatines,China Sell Fixed TV Monitor Bracket LCD Wall Mount (CT-PLB-113VBX), peptides or amino acids production (Stainless Steel Cross Recesed Flat Head Self Tapping Screw, 1991;Our Perforated Aluminum & Solid Panel for New Office Wall Cladding, 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;2019 Mobile Phone Accessories Original Lightning to 3.5mm Audio Adapter for iPhone., 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.Kids Trucker Hat, Kids Mesh Cap.

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%0.5 Gallons Cool Mist Ultrasonic Humidifier. 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.
