Vedclass · Answer

(D) Retting is a process that uses the action of microorganisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectin surrounding the bast-fiber bundles,and so facilitates the separation of the fiber from the stem. The retting of jute is primarily carried out by the action of $Butyric \ acid \ bacteria$ (e.g.,$Clostridium \ butyricum$). These bacteria decompose the pectin and other cementing materials,allowing the fibers to be easily extracted from the stem.
