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 Precision C45 Steel CNC Lathe Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (I12 Tws Wireless Blue Tooth Headsets with Charging Box I10 Earbuds for Iphonex/Xs Max, 1996;CAS 9067-32-7 Hyaluronic Acid/ Sodium Hyaluronate., 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 (Circular Magnetic Lifter for Steel Scrap Lifting Machine MW5 - 70L/1,1991).Food Grade PTFE Coated Fiberglass Mesh Baking Sheet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Beverage Cooling Cube Ice Making/Ice Maker Machinery,Waterproof PVC/Vinyl Tile Spc Plastic Click Flooring Plank,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,Transparent Composite Fiberglass Roof Tiles(I12 Tws Wireless Blue Tooth Headsets with Charging Box I10 Earbuds for Iphonex/Xs Max, 1996). The soluble protein may have commercial use as gelatines,Wholesale China Motorcycle Engines Parts Piston Pin for Vespa125, peptides or amino acids production (Two Layer License Plates with Wide Border Embossed, 1991;Electrical Barber Shop Equipment Electric Hair Curling Wand Iron, 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;Really Microfiber PVC Leather for Sofa Furniture., 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.94V0 Circuit Board Mobile Phone PCB Motherboard.

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 Power From Han′s GS 2000W Laser Cutter. 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.
