Three enzymes with ribonuclease activity, one of which also had deoxyribonuclease activity, have been isolated and partially purified from corn seeds and seedlings. The purification of Ribonuclease I from mature seed was previously reported. This enzyme has a pH optimum near 5.0, is loosely adsorbed to carboxymethyl-cellulose, and has a molecular weight of 23,000, determined by gel filtration.R...

Amylases and cellulases are important enzymes that can be utilized for various biological activities. Ten different wild Nigerian mushrooms (Agaricus blazei, Agaricus sp., Corilopsis occidentalis, Coriolus versicolor, Termitomyces clypeatus, Termitomyces globulus, Pleurotus tuber-regium, Podoscypha bolleana, Pogonomyces hydnoides, and Nothopanus hygrophanus) were assayed for production of these...

This work reports tests performed to evaluate the stability of aqueous dispersions of inorganic oxide pigments with different specific surface areas, with the use of anionic and non-ionic surfactants and concentrators. Color mixtures of oxide compounds of blue, green, olive and brown with the unit cell spinel structure were used as pigments. The sodium salt of sulfosuccinic acid monoester, oxye...

Human erythrocyte glucose 6-phosphate dehydrogenase (o-glucose 6-phosphate :nicotinamide adenine dinucleotide phosphate oxidoreductase, EC 1.1.1.49) was purified by column chromatography with diethylaminoethyl cellulose, calcium phosphate gel, carboxymethyl cellulose, diethylaminoethyl Sephadex, and carboxymethyl Sephadex. A homogeneous preparation was obtained in over-all yield of about 50%. T...

The complete computational study of the methyldopa drug and its derivatives prodrug 1-4(methyldopa-cellulose (Ce), methyldopa-carboxymethyl cellulose(CMC), methyldopa-maleic anhydride cellulose (MAC)and methyldopa-hydroxypropyl cellulose(HPC)) was performed by Density Function theory method with Becker’s three parameter hybrid functional (B3LYP) 6-31G++ (d, p) basis set using Gaussian 09 progra...

Vi khuẩn và nấm phân giải cellulose càng trở nên quan trọng hơn do có nhiều ứng dụng trong đời sống, đặc biệt hủy chất thải giàu sản xuất hữu cơ. Từ 6 tổ mối thu nhận ở huyện Bình Tân, tỉnh Vĩnh Long đã lập được 28 chủng vi 7 đều khả năng CMC (carboxymethyl cellulose), đó các đạt hiệu quả cao gồm 1BTL6 (61,7%), 3BTT6 (65,8%), 2BTNT5 (61,5%) 1BTNT3 (60,4%). Thêm vào đó, từ rơm tạo đường glucose ...

In this study, a bioadhesive dosage form of clotrimazole was designed using a combination of bioadhesive polymers Carbopol 934P, sodium carboxymethyl cellulose and sodium alginate in different ratios. The bioadhesive strength was evaluated by measuring the force required to detach the tablets from porcine vaginal mucosal membrane. The strong interaction between polymer and mucus lining of the t...
