Abstract
The experiment in a biotechnology laboratory of the Department of Food Science / College of Agriculture / University of Baghdad, in 2012 to study some of the important properties of cellulose produced from bacteria A. xylinum. SA1, a thickness of membrane cellulose, and ability to water holding, and study its porosity, and tensile strength, and measuring the degree of crystallization by examining (X-ray) and compared with cellulose plant and analyzing infrared spectroscopy (IR) to confirm his identity. Where the results showed that the thickness of the membrane was 3.3 mm, and its ability to water holding was high comparison with plant origin, and porosity of 49%, and the power intensity of 1.2 Mikabascal, as well as became clear that cellulose bacterial is more elaborate than cellulose plant and a factor of crystallization rate of more than 60 %, and when analyzing the infrared spectrum (IR) of bacterial cellulose to confirm his identity was found matching the shape of the infrared spectrum of Cellulose taken from the Encyclopedia of infrared spectra of chemical compounds. Also studied The effect of different agricultural media on the amount of Cellulose and the dry weight of the cells and the porosity and thickness of the Cellulose membranes were studied. In addition, the vaccine volume, incubation periods and alkali concentration used in the purification of the Cellulose membrane, and drying method on a porous membrane of Cellulose were highlighted. and influenced by different factors.
