Abstract
Acrylic fibers contain nano-silver and Nano-TiO2, are made of co-monomer of acrylonitrile .These fibers can be used in many different bases such as loom. Soil is one of the most important habitats of microorganisms which have vital role in different nutrient cycling. Some of these important microorganisms are Rhizobia which play an important role in cycle of nitrogen fixation and some bacilli which have cellulose enzymes and are essential in carbon cycle. In this study, R. cicil and Bacillus sp. were exposed to the acrylic fibers that contain nano-silver and Nano-TiO2, to investigate the effect of these fibers on these bacteria. Shake flask was the method used in this process and in different periods of time (0, 6, 24 hours) the colonies of bacteria were counted by drop plate method. The results showed that after 24 hours acrylic fibers which consist of nano-silver and nano-TiO2, have antibacterial effect on R. cicil and Bacillus sp. and decreased the growth of these bacteria to 72.61% and 78.09% respectively.
