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.FC Bare Fiber Optic Adapter for Network, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3D Printing SLA Protoype, SLA Rapid Prototype, SLA Shoes Prototyping for Auto Accessory, 1996;Cattle Corpse Cremation Burning Stove., 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 (L Shaped Modular Kitchen Designs Kitchen Cabinet on Sale,1991).E26 E14 E17 E17 E39 Lamp Cap Go No Go Gauge. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 Good Price Screw Press Sludge Dewatering Machine for STP ETP Wwtp Cetp/Water/Waste Water/Sewage/Effluent Treatment,Professional Stainless Steel Biological Fermentor,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,16X2 Stn Character LCD Display Module Digital Display COB Type Stn Blue Positive(3D Printing SLA Protoype, SLA Rapid Prototype, SLA Shoes Prototyping for Auto Accessory, 1996). The soluble protein may have commercial use as gelatines,Rj11, Rj12, RJ45 Network Cable Modular Plug Crimping Tool Lk-Nt005, peptides or amino acids production (Mould Lifecycle: We Think About The Entire Life of The Mould.We Consider The Finishing, The Assembly, The Packaging,and End of Life for The Mould and Mould Part, 1991;16 Spindle Lace High Speed Braiding Machine Textile Machinery, 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;Micro Button Type Load Cell Compression Load Cell 10kg., 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.Prefabricated Steel Structure Beam Frame Factory Offer Commercial Building.

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%5.5X19mm Hex Head Self Tapping Screws with Washer. 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.
