Electric Properties of Carboxymethyl Cellulose
Carboxymethyl cellulose [C6H7O(OH)3x(OCH2COOH)x]n is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxy ethanoic acid) CH2(OH)COOH or sodium monochloroacetate ClCH2COONa. The CMC backbone consist of D-glucose residues linked by -1,4-linkage. The molecular mass of one glucose unit in CMC chain is mCMC = 146.14 + 75.04x, where x 3 is the degree of substitu...
متن کاملNitrification by Aspergillus flavus.
Marshall, K. C. (Cornell University, Ithaca, N. Y.) and M. Alexander. Nitrification by Aspergillus flavus. J. Bacteriol. 83:572-578. 1962.-Aspergillus flavus has been shown to produce bound hydroxylamine, nitrite, and nitrate when grown in peptone, amino acid, or buffered ammonium media. Free hydroxylamine was not detected in these cultures, but it was found in an unbuffered ammonium medium in ...
متن کاملDevelopment of Aspergillus Flavus Af36
Aflatoxins are highly toxic cancer causing fungal metabolites known to cause immune-system suppression, growth retardation, liver disease, and death in both humans and domestic animals. Human exposure to aflatoxins is limited by regulations that prohibit the use of crops containing excess quantities of aflatoxins for foods and feeds. Aflatoxins are regulated in part per billion (ppb) ranges wit...
متن کاملComposite Hydrogels of Bacterial Cellulose - carboxymethyl Cellulose for Drug Release
Bacterial cellulose (BC) is a suitable material for biomedical applications due to its remarkable proprieties, such us: biodegradability, biocompatibility and ready availability. In this paper the swelling and drug release profiles from bacterial cellulosecarboxymethyl cellulose (BC-CMC) composite hydrogels were investigated, in the aim to use such systems in controlled drug delivery field. Ibu...
متن کاملStructural Identification of Lentinus edodes Cellulose Derivative that Inhibits Aflatoxin Production by Aspergillus flavus
Purpose: To identify the structures of cellulose-extract derivative (CED) formed by heating Lentinus edodes cellulose in water surroundings that can efficiently inhibit aflatoxin production by Aspergillus flavus. Methods: CED was purified on Sepharose CL-6B columns, and then structurally characterized using amino acid analyzer, gas chromatography, Fourier transform infrared spectroscopy, and po...
