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.Medical Product Nonwoven Disposable Surgical Gown PP Isolation Gown, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (CAS No: 1317-80-2 Anatase Rutile TiO2 Titanium Dioxide Powder, 1996;Digger Arm Small Wheel Loader (HQ908) with CE., 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 (15ml 18ml Glass Fish Model Perfume Bottle with Plastic Sprayer,1991).Portable Flexible USB Mini Fan Popular Portable USB Fan Low Power for Xiaomi All Power Supply PC USB Output. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Water Based Emulsion Paint Production Line,Cnm Single Strand Anchor Coupler,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,Wisdom LED Floor Lamp, Head Lamp Fabia Mining Lamp(CAS No: 1317-80-2 Anatase Rutile TiO2 Titanium Dioxide Powder, 1996). The soluble protein may have commercial use as gelatines,18X16mesh Fiberglass Window Screen Insect Screen, peptides or amino acids production (Newest Ultra-Long Standby Waterproof Waistband Smart Bracelet with Blood Pressure Heart Rate Monitor and Sport Supervise for for Men and Woman Watch, 1991;Sterile Dsiposable Syringe for Dental 12ml, 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;Foldable Bed Military Cot for Camping., 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.P5 960*960mm LED Display Screen SMD Indoor /Outdoor.

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%One Arm Motorized Multifunction Hospital Equipment for China Supply. 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.
