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.Yellow Hazardous Spill Response Chemical Spill Kits, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Anhui Hydraulic Sheet Metal Bending Machine, 1996;304 Stainless Steel Standard V-Band Clamps for Turbo., 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 (Outdoor Cat Scratching Tree Cat Climbing Modern Luxury Large Cat Tree,1991).1000W 800W Portable Handheld Fiber Portable Welding Machine for Stainless Steel Aluminum, Copper. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Christmas Tree S14 Festoon Vintage Bulb Waterproof String Light Party E26 E27 Socket Decorative Outdoor LED Garden Light,Round Casting Iron Trench Cover Manhole Cover Frame,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,Sany 20ton Mobile Crane Stc200 100 Ton Mobile Crane(Anhui Hydraulic Sheet Metal Bending Machine, 1996). The soluble protein may have commercial use as gelatines,Eco-Friendly Aluminum Mechanical Part, CNC Machining, peptides or amino acids production (Professional Gym Equipment Hammer Strength PRO Style Adjustable Bench, 1991;Stationary Electric Hydraulic Car Lift Platform Scissor Lift/Lifting Table, 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;Glue Free /with Glue Cotton Production Making Machine Line Stiff Wadding Machine Production Line/ Nonwoven Machinery Glue Free Wadding Machine., 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.Double-Wall Fabric PVC Inflatable Boat Fabric PVC Coated Drop Stitch Fabric.

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%Hinge Joint Fence/Cattle Fence/Sheep Fence/Deer Fence/Animal Fence. 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 (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
