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.New Leaf Shape Pearl Jewelry Wedding Tiara, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Starter Motor 0001367034 12V 3KW 9T for Mercedes, 1996;New Condition Hongyu Polystyrene Panel CNC Hot Wire Contour Foam Cutte., 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 (HPMC Hydroxy Propyl Methyl Cellulose Additives,1991).Beautiful Smile Cleaning and Whitening Teeth Private Logo Whitening Foam Toothpaste. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Tactical Outdoor Hunting Camouflage Rattlesnake Python Airsoft Shooter Suit,2019 Hiking Sleeping Folding Beach Air Sofa Lazy Bags,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,Customized Printed Decorative Mailing Bubble Bags in Bright Yellow Color for Envelopes Packaging(Starter Motor 0001367034 12V 3KW 9T for Mercedes, 1996). The soluble protein may have commercial use as gelatines,Large Diaper Bag Backpack, Mokaloo Anti-Water Maternity Nappy Bags Changing Bags with Insulated Pockets and Stroller, peptides or amino acids production (Multi-Storey Light Gauge H Section Steel Beam Framing Building for Workshop, 1991;Water Chiller Air Cooled for Cooling Beer Refrigerating, 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;High Quality Cheap Price Disposable IV Infusion Set with Precise Filter., 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.Q3210 Vibratory Polishing Shot Blasting Machine.

CONCLUSIONS

Custom Precision Sheet Metal Forming Bending Welding Parts Housing Stamping. 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.
