The Effects of Cellulose Particle Sizes on Bio􀅳lm from Longkong Peel

Abstract

The effects of longkong cellulose particle sizes on its biofilm were investigated. The particle sizes were divided into 355, 125 and 75 􀁷m. The X-ray diffraction patterns confirmed the cellulose phase with the secondary phase in some sample. The second phase did not affect biofilm preparation. The FTIR analysis suggested a strong presence of carboxyl and hydroxyl groups in carboxymethylcellulose (CMC) powder, which synthesized from the cellulose particle size 75 􀁷m. The SEM and EDS observations revealed that the cellulose particle size of 75 􀁷m produced a smooth surface and homogeneity of biofilm. The decrease in particle size induced significantly the high water solubility of CMC and high reaction surface area, leading to high quality of biofilm. The light absorption of all biofilms was not different significantly. Herein, the result suggested that a high quality of biofilm from longkong peel could be produced using the cellulose particle size 75 􀁷m, which may be alternative bioproduct in near future.
