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.Manufacture Hot Rolled Galvanized/Black U Shaped Iron Steel Channel Upn/Upe Good Price High Quality, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Arrival Educational Wooden Toddler Walking Toys for Push Along W16e115, 1996;China Sell Fixed TV Monitor Bracket LCD Wall Mount (CT-PLB-113VBX)., 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 (Stainless Steel Cross Recesed Flat Head Self Tapping Screw,1991).Our Perforated Aluminum & Solid Panel for New Office Wall Cladding. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 Mobile Phone Accessories Original Lightning to 3.5mm Audio Adapter for iPhone,Kids Trucker Hat, Kids Mesh Cap,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,Wd190V Handheld Full Body Scanner Hand Held Metal Detector(New Arrival Educational Wooden Toddler Walking Toys for Push Along W16e115, 1996). The soluble protein may have commercial use as gelatines,Dead Sea Mud /Aloe & Dead Sea Mud/Snail &Dead Sea Mud Black Mask Remove Blackhead Mask Box-Packed, peptides or amino acids production (Hydraulic Orbital Valve Power Steering, 1991;W11S-20X3200 Hydraulic Universal Three Rollers Sheet Plate Rolling Bending Machine, 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;AISI 410 Stainless Steel Galvanized Wire for Making Scourer., 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.CS1363 a Standard UK 3 Pin Power Plug.

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%Dual Working Solar Motion Wall LED Lamp Light From ISO9001 Factory. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
