Title: Jute Retting: An Overview Author: Zakaria Ahmed and Firoza Akhter Subject: Journal of Biological Sciences Keywords: Jute, retting, bacteria, fungi Ribbon retting reduces time of normal retting … Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. The jute is taken from the stem and the skin of the stem, which is called the ribbon. Jute (Corchorus capsularis and C. olitorius), Kenaf (Hibiscus canabinus) and Roselle/Mesta (Hibiscus sabdariffa) constitute very important fibre and cash crops of the world (Ali, 1990 and 1992).Total global production, about 3 million tons, of jute/kenaf, are harvested per ha. subtilis, three strains ofB. Pectinolytic microorganisms are also responsible for retting, the central step in the textile production of vegetal fibres, such as flax, hemp, ramie and jute. The … Jute is the common name given to the fiber extracted from the stems of plants belonging to the genus Corchorus, family Tiliaceae. This study aims at focusing the effect of jute water-retting process on aquatic lives and hence developing a pilot-scale treatment process. However, another species of jute, called Corchorus capsularis (tossa jute) is considered to be superior even though it is harder to cultivate. The pH of the water after repeated retting had dropped to 6.0, but the quality and colour of the fibres was unaffected.

Abstract BBS.2008. ... and the bundles submerged in water for retting. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. This technique has been found easier and cost effective for jute retting by the jute growers in India. Jute is a natural fiber that is mainly grown across West Bengal in India and in Bangladesh with some also grown in Myanmar, Uzbekistan, Thailand and china. isolated fromretted jute are responsible for theprocess, as for instance, seven species of aerobic bacteria were isolated fromretted jute but only oneof them, B. poly-myxa, was capable of retting jute in laboratory tests. In Bangladesh, Jute is a vital sector from economical, agricultural, industrial, and commercial perspectives. BAST FIBRES • Bast fibres come from the stem of the plant. Jute fibre is the second most important fibre next to cotton. Retting If hemp or flax (linen) fibers are to be used in textiles and other high-quality applications, the bast fibers must be separated from the rest of the stalk. Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality.
