Natural cellulose fibers are extracted from lignocellulosic byproducts using bacteria and fungi, mechanical and chemical methods. Retting, the traditional process to extract fibers, uses bacteria and fungi in the environment to remove lignin, pectin and other substances. Bacteria such as Bacillus and Clostridium, used in water retting, and fungi such as Rhizomucor pusillus and Fusarium lateritium, used in dew retting, are found to be most effective in their ability to attack the noncellulosic substances and separate the fibers from the core. Although atmospheric retting provides better quality
fibers, it requires relatively longer duration and it is difficult to control the fiber quality.
