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.Gauge 30 Tile Red Durable Roofing Profiles PPGL Steel, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Horizontal Directional Deep Hole CNC Drilling Machine for Sale Metal Plates, 1996;Colorful  Reflective Sticker Reflective Tape., 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 (Concrete Spare Part Electrical System Central Distribution Box,1991).Bedroom Furniture Pillow Top Memory Foam Natural Latex Pocket Coil Spring Mattress. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,50Hz to 60Hz Frequency Inverter for Water Pump,Metal Universal Vertical Turret Milling Machine (X6323 X6325 X6325D X6330),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,High Quality Horizontal and Vertical Metal Universal Turret Milling Machine (X6325)(Horizontal Directional Deep Hole CNC Drilling Machine for Sale Metal Plates, 1996). The soluble protein may have commercial use as gelatines,4X8 Waterproof PVC Marble Sheet Wall Panels Decorative Bathroom Wall Panels, peptides or amino acids production (Vvvf Golden Mirror Sightseeing Passenger House Panoramic Home Observation Elevator, 1991;PVC Cabinet Construction Board, White 18mm PVC Foam Board, 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;2019 New Portable Mini Dental X-ray Machine., 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.Ss Reduced Port 2000wog 1PC Screwed Ball Valve.
