The whole process is known as retting Retting, process employing the action of bacteria and moisture on plants to dissolve or rot away much of the cellular tissues and gummy substances surrounding bast-fibre bundles, thus facilitating separation of the fibre from the stem. • The microorganisms, mostly bacteria from retting water enter the plant tissues through the stomata, epidermis and cambium or the cut end, when immersed in retting tank, and through their enzymatic action loosens the fibre strands from the woody core. Enhanced retting was observed in stems sprayed with B. subtilis and consequently the stems produced finer fibres than fibres from E. carotovora-sprayed or control stems.
