retting of jute is caused by which bacteria

Appl. 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. 1 decade ago. Jute is associated with the process of Retting. subtilis, three strains ofB. Retting operation was carried out for varying time period namely 10, 15, 20, 25, 30 and 35 days respectively. Angewandte mikrobiologische Untersuchungen über die Wasserröste der Faserpflanzen. Fibers of jute are held together in close association and they are separated by the action of butyric acid bacteria e.g. They were classified in 3 genera, Bacillus, Micrococcus, and Pseudomonas and 13 species. However, bacterial communities associated with the retting of jute are not well characterized. Bacteria and fungi act upon the soft tissues of the stem, which on dissolution makes it easy to separate the fibre from the core (stick). Abstract BBS.2008.

It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. For retting of jute the fermenting microbe used is. Retting of jute is done by Clostridium butyricum. Water retting and dew retting apply anaerobic bacteria fermentation and the fungi colonisation method, respectively, on fibre bundles, to produce enzymes that hydrolyse fibre-binding components. It is traditionally carried out in water bodies and basically a microbiological process. A.
