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.Wholesale China Merchandise 12V Horizontal Mini Camping Fridge, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (20FT /40FT Prefabricated Modular Mobile Prefab Wooden Living Portable Shiping Steel Luxury Tiny Moveable Office Prefab House, 1996;No Toxic Lead Free Hardness Surface PVC Foam Board/Sheet., 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 (2D LED Rope Lighting Motif Lights for Christmas Decoration,1991).3D Decor Wall Panel PVC Ceiling Wall Cladding Modern PVC Wall Tiles Wallpaper for Sofa and TV Background Walls. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,10ml Dropper Bottle for Skin Care Packing,Custom High Precision Micro Machining Service Brass Micromachining Parts,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,7PCS/Set Eco Friendly Camping Travel Portable Reusable Natural Organic Bamboo Utensils Flatware Cutlery Set with Bag(20FT /40FT Prefabricated Modular Mobile Prefab Wooden Living Portable Shiping Steel Luxury Tiny Moveable Office Prefab House, 1996). The soluble protein may have commercial use as gelatines,Replacement Cell Phone LCD for iPhone 6s Spare Parts, peptides or amino acids production (China Manufacturer Lm800 Forklift Trucked Mounted Drum Lifter, 1991;Explosion Proof Fog Cannon for Coal Plant, 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;Silicone Large Non-Stick BPA Free Baking Mat Sheet., 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.19mic Black Cast PE Stretch Film for Pallet Wrapping.

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%Supply Christmas Lace Gold Silver Offray Silk Ribbon. 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.
