Answer: Process of retting helps in separation of pulpy material of the stem from the jute fibres. Several soil quality parameters influence fiber quality. L.), the golden fibre, is an important cash crop of Eastern India, and India earns about 2050 crores rupees annually by exporting diversified jute products. â¦. Not all bacteria 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. All these results indicates that jute-retting is may not be the one and only factor to deteriorate the water quality of ponds. 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. Harvesting, Retting, and Fiber Separation Harvesting and fiber processing differ depending on whether the crop is grown for high-quality textile fiber, for seed, or for fiber and seed. For 10,000kg of jute, approximately 432m3 of water is used in water-retting process (Huda et al., 2012). These findings reveal important bacterial groups involved in fiber retting, and suggest mechanisms for the manipulation of the community and retting efficiency by modifying nutrient availability. It is a gram-positive butyric acid producing bacteria. Enzymatic pretreatment of natural fibers for composite applications was reviewed in the light of existing literature. Biol. (Ahmed, 1963;Ali and Alam, 1983;) The different researches so far done are aimed at the major objectives concerned with: 1) Chemical composition of Jute plants, 2) Chemical and microbial composition of retting water , 3) Mechanisms of retting, 4) Retting microorganisms and their use in retting practices, 5) Acceleration of retting speed, 6) Reduction of fibre cuttings, 7) Improvement of fibre strength, 8) Improvement of fibre colour, Lustre and texture 9) Retting methods for water scarce areas, 10) Jute ribbon retting, 11) Retting of seed plants, 12) Production of Bio-gas from jute retting effluent, 13) Effect of jute retting on fish farming, 14) Relationship between lignin and pectin content with plant maturity and fibre quality of jute, 15) Comparative retting properties and fibre quality of Corchorus capsularis and Corchorus olitorius jute, Hibiscus cannabinus (Kenaf) and Hibiscus sabdariffa (Mesta), 16) Provision of retting water facilities, 17) Retting technique in rice field and finally 18) Up-gradation of Special Mora Islam and Rahman 21 Rejection SMR and low grade barky jute fibre through the application of fungi. The role of microorganisms obtained from jute (Corchorus spp.) Both these organisms were non-pectolytic and unable to ret flax. Three strains ofBacillus macerans, four strains ofB. The Oregon study, Feasibility of Industrial Hemp Production in the United States Pacific Northwest, summarizes current information and research on hemp harvesting, retting, the hard bottom parts of the fibre. Studies on Some Strains of Butyric-Acid-Producing Plectridia Isolated from Hemp, Jute and Flax. Active retting strains have been found to lose their retting activity, and it has been concluded that this loss may follow either from loss of adaptive enzymes or from mutations. Ich habe aus 27 Fällen von inficierten Wurzelkanälen zuerst aerobe und anaerobe Bakterien differentiert, und dann jede mikroskopische und biologische Beschaffenheit von beiden Bakterien eingehend, Based on the results of the authors' own investigations and the reported data it is shown that primary (extrahospital) acute pneumonia (AP) is of pneumococcal etiology in the overwhelming majority of patients. To find out specific way(s) to minimize or eradicate this transitory pollution further research is required. jute fibre and the demand for quality fibre by jute mills is getting momentum. butyricum, were the major sporulating organisms found on English flax. Natural fibres are a gift from nature that we still underutilise. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. ... felsineum are considered as the major retting agents (Hellinger, 1953; Vonzyakovskaya et al., 1974); Bacillus, Pseudomonas and Micrococcus spp. Bacillus polymyxa, which attacks pectin and is a moderately active retting agent in aerobic and anaerobic rets, was occasionally found. At the same time in 2/3 of cases, AP is associated with influenza and other acute respiratory virus infections. Und zum Ende habe ich mit diesen Bekterien mehrfache Tierexperiment gemacht. These findings encompass a strong foundation for fundamental and evolutionary studies on this unique microbial degradation of decaying plant material with immense industrial significance. How much thermal energ Natural fiber substrates for enzymatic action were presented. sible for the retting of Brazilian flax. This organism was remarkably pectolytic and an active retting agent. These bacteria appear to be naturally associated with the plant material, although slight variations between source materials were found. National Institute of Research on Jute and Allied Fibre Technology, Kolkata has evolved a cost effective retting technique by which the quality of jute bre has been possible to be up-graded at least by one grade.
