Jarman, C. G. The retting of Jute. To investigate the presence of microorganisms during the process of jute retting, full-cycle rRNA approach was followed, and two 16S rRNA gene libraries, from jute-retting locations of Krishnanagar and Barrackpore, were constructed. It is a gram-positive butyric acid producing bacteria. 1996;21:71–80. The repeated retting of jute and mesta in the stagnant water of same natural retting tank lead to the production of inferior quality fibre unless the tank is recharged with fresh water after each retting. Ali MH, Samad MA, Sarker NN. -. The water, penetrating to the central stalk portion, swells the inner cells, bursting the outermost layer, thus increasing absorption of both moisture and decay-producing bacteria. Decorticated kenaf stalks were retted by bacterial and chemical processes. 2003;6:686–687. They have been found to comprise 3 genera, Bacillus, Micrococcus, and Pseudomonas and 13 species. Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Jute and kenaf are among the annually renewable fibre crops mainly grown over tropical and subtropical Asian countries. Djemiel C, Goulas E, Badalato N, Chabbert B, Hawkins S, Grec S. Front Genet.

Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. Higher pectinolytic bacterial isolates were predominant in the later stage of jute retting. An in situ microbial retting process with direct involvement of the bacterium on the ramie fibre as a carbon source, rather than treating fibre bundles with enzymes secreted by bacteria, was highlighted. Jute fiber is being dehydrated in sunlight after natural or microbial retting Retting is the process of extracting fibers from the long lasting life stem or bast of the bast fiber plants. Retting microbes present in plant and water continue to build up their population by utilizing these soluble compounds.
