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.ETL cETL Dlc 150 Watt LED Street Light for Parking Lot Lighting, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Performance Alcohol Pad Making Machine, 1996;Ss304 Sanitary Welded Butterfly Valve., 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 (2019 New Design Flat Panel Print 3D Microfiber Cartoon Bedding Set,1991).Anti-Abrasion PVC Artificial Leather for Car Seat (128#). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Digital Control with LED Display DC Solar Small Deep Freezer Fridge,Automatic Economical Check Weigher with High Speed,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,Small Lovely Girls′ Backpack Plush Backpacks with Stitching Pocket(High Performance Alcohol Pad Making Machine, 1996). The soluble protein may have commercial use as gelatines,Steel Handle Rake Flat Rake Garden Rake Agricultural Rake, peptides or amino acids production (High Quality Small Tea Bag Packing Machine Price, 1991;Carbon Dioxide Gas with 50L Seamless Cylinder, 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;UV8d Wouxun High Gain Antenna Dual Band Antenna., 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.Fiberglass Covered Insulated Flat/Square Aluminum Magnet Wire.

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%Bag Accessories 10mm Metal Dog Swivel Snap Hook, Wholesale Antique Brass Trigger Snap Hook for Bags. 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.
