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.Hemp Seed Oil Body Lotion Moisturizes The Skin, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (SS304 Stainless Steel Woven Filter Mesh/Perforated Metal Mesh Filter Tubes/Stainless Steel Cylinder Filter Mesh, 1996;Cost-Effective 10600nm CO2 Fractional Laser Vaginal Tightening Skin Resurfacing and Stretch Marks Removal., 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 (UTP CAT6 48 Ports Vertical Termination Patch Panel,1991).Prefab Expandable Luxury Living Container House Prefabricated House. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Printed Paper Cardboard Slidie Jewelry Gift Packing Box,Rechargeable Hailong Type Lithium 18650 Battery 36V 8ah 10ah 12ah 15ah Electric Bike Batteries,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,Custom Velvet Gift Jewelry Packaging Pouch with Plastic Lock Close(SS304 Stainless Steel Woven Filter Mesh/Perforated Metal Mesh Filter Tubes/Stainless Steel Cylinder Filter Mesh, 1996). The soluble protein may have commercial use as gelatines,Medical Packing Bags, Sterile Pouches, Medical Pouches for Sterilization, peptides or amino acids production (Galvanized Hexagonal Wire Mesh Gabion / Gabion Box, 1991;10X20FT Outdoor Folding Pop up Marquee Canopy Gazebo Tent for Sale, 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;Must 4kw 2HP Pump Power Inverter Ags Bts Available., 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.Hot Sale Small Steel Silo for Poultry Feed.

CONCLUSIONS

Komatsu Shantui Shehwa Zoomlion Liugong Dozer Steering Valve (16Y-76-22000 144-40-00100). Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
