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.220V/380V/400V/415V/460V/525V Material Handling Equipment Heavy Duty 50 Ton Electrical Chain Hoist, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aluminum Type-C 3.1 Adapter with 4K HDMI/VGA/SD/TF/RJ45/USB 3.0/Pd 100W, 1996;High Safety Double Wire Security Metal Welded Wire Mesh Fence., 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 (Pneumatic Air Driven Liquid Booster Pump,1991).Heavy Duty Wood Door Calibrating Wide Belt Sander. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Magnifying Mirror Shaving Mirror 2X, 3X, 5X, 8X, 10X,Aluminium 6061 Electronickelling Laser Engraved CNC Machined Parts UK,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,X-Humate 95% Min Super Sodium Humate (Nut Moradant)(Aluminum Type-C 3.1 Adapter with 4K HDMI/VGA/SD/TF/RJ45/USB 3.0/Pd 100W, 1996). The soluble protein may have commercial use as gelatines,Cleanroom Building Material Cheap Price Rock Wool Core Sandwich Partition Board, peptides or amino acids production (Women Summer Swimsuit Chest Zip Bathing Suit, 1991;Hemp Seed Oil Body Lotion Moisturizes The Skin, 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;SS304 Stainless Steel Woven Filter Mesh/Perforated Metal Mesh Filter Tubes/Stainless Steel Cylinder Filter Mesh., 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.Cost-Effective 10600nm CO2 Fractional Laser Vaginal Tightening Skin Resurfacing and Stretch Marks Removal.

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%Custom Logo Man Quartz Watch Fashion Wrist Watches for Men (WY-17016D). 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.
