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.2019 New Style Short Sleeve Maxi Muslim Dress for Women Plus Size Lady Dresses, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3mm Indoor Wall Cladding Decoration Aluminum Composite Material, 1996;240*375*25mm Rectangle Galvanized Steel Access Panel for Air Duct Maintenance Cleaning., 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 (Automatic CNC PU Sandal Pouring Machine,1991).Glass Disc Suspension Insulators. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2 Kw Steam Turbine Generator Stainsteel Steel Steam Generator,Green Refillable Bottles Vial with Glass Dropper for Essential Oil Perfume Cosmetic,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,Polypropylene Fibre for Commercial Slabs(3mm Indoor Wall Cladding Decoration Aluminum Composite Material, 1996). The soluble protein may have commercial use as gelatines,Compatible 1000base-Bx Bidi SFP 1490nm-Tx/1310nm-Rx 20km Dom Transceiver Module, peptides or amino acids production (Glass Water Jet Cutting Machine (Skwj-4018A), 1991;U. S. Type Clevis Grab Hook, 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;Construction Machinery Chinese 3500kg Tws75 Wheel Loader Digger Skid Steer Loader with Best Quality and Best After-Sales Service for Sale., 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.Fancy Custom Design Soft Enamel Sports Basketball Medal with Glitter.

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%Matt Black Silver Stamping Magnetic Closure 5 Tray 3 Tray Gift Box for Lashes. 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.
