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.Security Shopping Trolley Baby Seat for Supermarket Cart, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Desktop & Walmount Workstation with Gas Lift Floorbase Double Monitor 10-24, 1996;Minimalism Small Portable Laser Engraver Fiber for Metal Plastic Key Gun Rubber PVC Glass Yeti Cup., 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 (Indoor Decorative 3D Vision Artistic Effect Wall/Ceiling Background LED Panel,1991).Htw160jd Haitai Pet Bottle Preform Cap Making Box Spoon Full Automatic Plastic Injection Molding Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customized Cheap Interlocking Rubber Paver or Flooring for Crossfit Gym Use,Manual Foot Pedal Hydraulic Pump,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,860~960MHz UHF RFID Adhesive Tag/Sticker/Wet Inlay/ Long Range Logistic Tag(Desktop & Walmount Workstation with Gas Lift Floorbase Double Monitor 10-24, 1996). The soluble protein may have commercial use as gelatines,Hot Sale High Quality Rimless New Italy Design Titanium Eyeglasses for Business Men and Women, peptides or amino acids production (CH Series Pid Intelligent Temperature Controller CH402, 1991;China Cast Steel Wafer Butterfly Valve Pn16 Dn150 Factory, 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;Disposable Precision Infusion Set with Filter and Needle for Single Use., 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.Low Price Sweep Frequency Response Analyzer for Power Transformer Test.

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%100%Polyester Burnout Velvet Sofa Fabric (pineapple grid). 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.
