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.


Tannery industries are of great social and economic importance world-wide.Super Fireproof Antibiosis Household Spc Vinyl Floor Plank, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Feet Protection Industrial Cow Split Leather Working Safety Shoes, 1996;Soldering Machine LED Module PCB Hot Air Soldering Station., 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 (220V/380V/400V/415V/460V/525V Material Handling Equipment Heavy Duty 50 Ton Electrical Chain Hoist,1991).Aluminum Type-C 3.1 Adapter with 4K HDMI/VGA/SD/TF/RJ45/USB 3.0/Pd 100W. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Safety Double Wire Security Metal Welded Wire Mesh Fence,Pneumatic Air Driven Liquid Booster Pump,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,Heavy Duty Wood Door Calibrating Wide Belt Sander(High Quality Feet Protection Industrial Cow Split Leather Working Safety Shoes, 1996). The soluble protein may have commercial use as gelatines,Magnifying Mirror Shaving Mirror 2X, 3X, 5X, 8X, 10X, peptides or amino acids production (Aluminium 6061 Electronickelling Laser Engraved CNC Machined Parts UK, 1991;X-Humate 95% Min Super Sodium Humate (Nut Moradant), 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;Cleanroom Building Material Cheap Price Rock Wool Core Sandwich Partition Board., 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.Women Summer Swimsuit Chest Zip Bathing Suit.

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%Ms Gi Pipe Dn15~Dn400 Gi Pipe List. 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.

The total volume (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
