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.Wood Veneer Peeling and Clipping Combined Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Original Smartphone for Huawei P20 Lite Global Firmware 4G Lte Mobile Phone Face ID 5.84 Screen Android 8.0 Front Camera 4GB 128GB ROM Cellphone, 1996;Wholesale High Quality Decoration Oil Painting, Home Decoration Painting, Art Painting (abstract sailing oil painting)., 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 (Si3n4 Full Ceramic  Bearing  608 Size 8X22X7,1991).32W Dimmable Interior Ceiling LED Recessed/Flush Can/Spot Down Lights for Office/Hotels/Shopping Mall. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Kara Two-Way Dual 8′′ Line Array PRO Audio System Powerful PA Speaker,Corrugated Board Production Line,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,Magnesium Sulphate/ Chemical Fertilizer Magnesium / Aquaculture Addtive(Wholesale Original Smartphone for Huawei P20 Lite Global Firmware 4G Lte Mobile Phone Face ID 5.84 Screen Android 8.0 Front Camera 4GB 128GB ROM Cellphone, 1996). The soluble protein may have commercial use as gelatines,Car Air Conditional Compressor Magetic Clutch 5pk, peptides or amino acids production (High Quality Engieered Veneer Faced Commericial Plywood, 1991;Hex Thin Head Nut, 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;Pharmaceutical Peptide Ghrp 2 Acetate CAS158861-67-7 Ghrp-2., 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.Big Capacity Crystal Clear Glass Wine Bottle with Screw 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%1220 Fork Length 3-Wheel Electric Forklift Truck. 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.
