Genome sequencing also confirms that retting bacteria degrades pectin, hemicellulose and other non-cellulosic materials, non-harmful for fibre. polymyxa, five strains ofB. Aerobic Bacteria Involved in the Retting of Jute MOHAMMAD MYSER ALIL Departmtlent of Botany, University ofDacca, Dacca, East Pakistan Received for publication Juine 15, 1957 Jute, Corchorus capsularis, is the most important cash crop of Pakistan. Pectinolytic microorganisms are also responsible for retting, the central step in the textile production of vegetal fibres, such as flax, hemp, ramie and jute. Clostridium butyricum is used in the process and these bacteria hydrolyze the middle lamella of these plant fibres. 1. Besides In Biogas plants, the bacterium called Methanobecterium is used for production of Methane. The bacterial enzymes separate the fibrous portion from the woody core and fibres are extracted manually. The bacterial strains are also non-toxic and thus the retting water with microbial strains can successfully be used for irrigation purpose. mdfarooq78 mdfarooq78 16.09.2018 In our study, a mixed bacterial retting culture, developed in our institute, was inoculated during ribbon retting of jute. Jute fibre, the second most common natural cellulosic fibre in the world, is currently attracting more attention than the petroleum-based fibres (Liu et al., 2010).The retting process is the major limitation to an efficient and high quality fibre production, thus being the key feature in any future expansion of this industrial crop. Introduction. A highlighted synergetic effect of combining microorganisms resulted in better PG (35.52–46.61 IU/g), pectin lyase (39.79–72.12 U/ml), and xylanase (0.705–0.840 µ mol/ml/min) activities. Answer: Jute plants are cut at the flowering stage when plants are 8-10 feet high. What is retting? 1976), resulting in the reduction of growth of retting bacteria compared to higher growth observed at initial and middle stage of retting. Four bacterial strains from Bacillus strains with high PG, PAL, and xylanase activities with minimal cellulase tracks were used in jute fibre retting . megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. 1. cereus, one strain ofB. luteus were isolated and their action on jute stems studied. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. subtilis, three strains ofB. Eleven jute fibre extraction machines have been distributed among 11 farmers free of cost in the district. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. Three strains ofBacillus macerans, four strains ofB. 2. Explain how fibres are obtained from the jute plants. Retting is a process in which the tight bundles of jute stalks are taken to the tank by which the fibres get separated from the wooden stalk. Microbial retting consortium can be used for efficient retting either for ribbon retting or whole plant retting during water scarcity situation utilizing minimum amount of ground water. The cut plants are grouped at different places in the field for few days when most of the leaves dry … Bacteria are useful in the Fibre ratting in which the fibres of Jute, hemp and Flax are prepared. Jute fibre is chemically ligno-cellulose in nature. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. Historically used in textile and paper industry, hemp fibres have started to find new applications in composite materials with important economic and ecological advantages. However, their applications are limited since manufacturers have some difficulties to standardise fabrication processes. There are two improved techniques of microbial retting developed by CRIJAF are a) Mechano-microbial retting and b) In-situretting of whole plant jute.
