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.High Quality Garden Tools 22t Carbon Steel Leaf Rake with Fiberglass Handle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ye3 Ie3 Premium Efficiency IC411 Tefc Three Phase AC Electric Induction Motor High Pressure Washer Ye3-160L-2 18.5kw, 1996;Air Compressor Replacement Parts 1622379881 2901146500 Automatic Drain 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 (Polished Tzm Molybdenum Alloy Plate,1991).Iron Welded Gabion Basket Retaining Wall. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customizable Oxygen Concentrator 20 Lpm Pressure Swing Adsorption Plant,Manufacturer of Rice/Wheat Straw Sawdust Crushing Making Mill for Sale,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,Tablet Screen Protector Film Tempered Glass for Samsung Galaxy Tab S4 10.5 T830 T835(Ye3 Ie3 Premium Efficiency IC411 Tefc Three Phase AC Electric Induction Motor High Pressure Washer Ye3-160L-2 18.5kw, 1996). The soluble protein may have commercial use as gelatines,FTTX Solution Provider Fiber Optical 12cores MPO Cassette, peptides or amino acids production (Yidek 3 Phase 4 Wire Automatic Digital Power Analysis Testing Analyzer, 1991;Aluminum Height Adjustable Cane, 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;Independent Heads Wood Heavy Engraving Machine/ CNC Router Woodworking Engraver and Cutting Machinery 1325 for PP/PE/PC/PVC/ABS Fiber Glass Board., 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.Large Batches Equipoise Light Yellow Liquids.

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%Die-Casting LED Projector Light 840W Outdoor Sport Field Light High Mast Light 150lm/W. 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.
