Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality. Basic methods include dew retting and water retting. the case whether or not jute-retting bac-tera were added at the outset. BAST FIBRES • Bast fibres come from the stem of the plant. Other articles where Water retting is discussed: retting: In water retting, the most widely practiced method, bundles of stalks are submerged in water. The defoliated jute bundles are then transported to the nearby retting facilities, immersed in clean or stagnant water according to the availability in natural retting tank, road-side ditches, sometimes in … This study aims at focusing the effect of jute water-retting process on aquatic lives and hence developing a pilot-scale treatment process. Retting is a microbial process that breaks the chemical bonds that hold the stem together and allows separation of the bast fibers from the woody core. S ummary: A total of 1,438 colonies of aerobic and anaerobic bacteria has been isolated from samples of retted jute stems collected from 12 districts of East Pakistan. However, another species of jute, called Corchorus capsularis (tossa jute) is considered to be superior even though it is harder to cultivate. A total of 451 bacterial colonies have been isolate … Introduction. While there are a few different botanical varieties of jute, one of the main species used to make jute fabric is Corchorus olitorius (white jute). megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. polymyxa, five strains ofB.
