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.Cheapest 250ml 300ml 400ml 500ml 800ml Voss Glass Water Bottles, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Casting PE Film with Ash for Adult Diaper Back Sheet, 1996;Supra Brand Laundry Liquid Baby Formula., 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 (Customized Aluminum CNC Machinery Die Casting Aluminum Housing Car Interchanger,1991).Cleaning Products Sponge Vacuumized Pack 65mm. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mineral Water Bottle Mould Plastic Blowing Mold,High Quality Acrylic/PVC/Kt Foam Board, Outdoor Advertising Sign Boards,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,6000PCS/H Automatically Paper Recycling Egg Tray Moulding Machine(Casting PE Film with Ash for Adult Diaper Back Sheet, 1996). The soluble protein may have commercial use as gelatines,Class 1/Class 2 Birch Plywood for Automotive and Boatbuilding Applications, peptides or amino acids production (Cookies Cake Automatic Rotary Packing Machine, 1991;Building Material Quick Install Types of Scaffolding Couplers, 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;Latest New Upgraded High Security and Regular Keys Cutting Machine Sec-E9 for Automobile Industury., 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.Hearing Aid Accessories Silicon Straight Tube Curved Tube for Rec and Mic.

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%86 Inch All-in-One Android System Interactive Touch LCD Kiosk for Education/Meeting. 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.
