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.Pond Self Priming Booster suction  Water Pump with Pressure Switch, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Digtal Camera for Sewer Line Inspection System with Self Level and Meter Counter, 1996;Modern Furniture Brick Finishing Wood Fireplace Mantel Surround Electric Fireplace., 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 (for Wall Decoration Glass Silver Metal Aluminium Mosaic Tile,1991).100% Polyester Gabardine Shirting Fabric with Transfer PrintingTree. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,School Kid Sport Travel Backpack Fashion Casual Promotional Bag (GB#20056),Fuguang High Quality Fb1015-280 280ml Double Wall Glass Water Bottle,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,Lamella Clarifier for Industrial Wastewater Flocculation and Sedimentation(Digtal Camera for Sewer Line Inspection System with Self Level and Meter Counter, 1996). The soluble protein may have commercial use as gelatines,0.8ton 800kg Mini/Small Hydraulic Crawler Excavator Garden Digger Machine, peptides or amino acids production (125kHz RFID Hotel Key Card with T5577 Chip, 1991;USB Smart Power Strip Socket 1875W with Adhesive Board Socket 3 AC 3AC Outlets 2 USB Charging Ports for Home Office Plug, 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;Fashion Large Capacity Transparent PVC Leather Handbag Tote Shopping Bag., 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.Crop Fertilizer Agriculture Nh4cl Ammonium Chloride.

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%High Strength Rigid PVC Plastic Foam Board for FRP. 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.
