In addition, the inoculation treatment with P. longanae significantly promoted the activities of CWDEs including pectinesterase, polygalacturonase, β-galactosidase, and cellulase. ... For bacterial degumming, some researchers have studied the screening and community structure of degumming bacterial strains of jute (Banik et al. 5th and 6th February 1998, Calcutta, A NIRJAFT publication. Pulp yield of conventional retted jute fiber and jutestick was higher at any kappa number.

The fibres are first extracted by retting. introduced ribbon retting in Bangladesh for jute-retting process. either in a water solution or sprinkled directly in the layers of the jute bundle in jute jaks. Retting may be defined as the separation of bast fibres from the core tissues of the stem. The main purpose of this study was provided information about the status of present jute retting process as well as mentioned the advantages and disadvantages of different jute retting processes. After the retting process… Microbial inoculation produced remarkable improvement in jute fibre strength (26.62–28.91 g/tex) and fineness (2.76–2.92 tex) over control. Kena fbast fibers were extracted using different methods (crude, decorticated, water retted, 5% sodium hydroxide retted and 5% benzoate retted) and their physicochemical characteristics were investigated. Haque et al. Ribbon retting requires lesser volume of water, lesser time, creates lesser environmental pollution, and produces improved quality fibre. The microorganisms in dif-ferent combinations of consortia showed synergistic effect resulting in increased PG (35.52–46.61 IU/g cell wet weight), PNL (39.79–72.12 U/ml), xylanase (0.705–0.840 mol/ml/min) and little cellulase (0–0.153 mol/ml/min) activities. Enzymatic retting has apparent advantages over other retting processes by having significantly shorter retting time and acceptable quality fibres, but it is quite expensive. ii) Retting of green ribbons with microbial consortium. Almost 85% of the world's jute cultivation is concentrated in the Ganges Delta. Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process.From the present study it is understood that inoculation of a specific mixed bacterial culture in combination with 0.5% urea as N-supplement caused faster ribbon retting of jute and kenaf. Many fungal elements were bound by only a thin or defective lucent wall layer, practically unlabelled for chitin, or by a locally thick- ened, labelled one; labelling for this substrate was also frequently associated with the fungal cell outer opaque wall layer or with some outer extracellular matter. All the isolated bacteria as well as fungi possess pectinolytic activity. This study presents a post-facto evaluation of the local capacity development processes used under co-management of fisheries and other resources of southern Bangladesh. Moreover the wash water arising due to rinsing of retted fibre was recycled, thereby achieving a zero discharge concept. A detailed study of chemical, physical and mechanical properties will bring out a logical and reasonable utilization of PALF for various applications. Different aspects of retting, right from quality and quantity of retting water, microorganisms with balanced pectinolytic and xylanase activities with minimal or low cellulase activities, largely determine fiber quality. In this review, author covered the basic information of PALF and compared the chemical, physical, and mechanical properties with other natural fibres. Jute retting process is one of the important responsible factors for quality of jute fiber. The fibres are then covered by Ca(OH)2 nodules after immersion in a lime solution. A special type of machine with metal knife scrapper roller and serrated roller has been developed and used to scrap out the waxy layer and at the same time macerating and breaking the leaf surface for ease of retting to extract the pineapple leaf fibres. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. Results indicated that storage modulus was decreased for all composites with increases the temperature and pattern of slopes for all composites had almost the same values of E' at glass transition temperature (Tg). The mechanical, physical strength and chemical compositions of natural fibers strongly depend on harvesting, climate, location, soil characteristics and weather circumstances. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography etc. Direct penetration of host cell secondary walls by the pathogen occurred, but these were degraded to any extent only following intramural invasion. It indicates that retting of corn leaves for longer periods leads to degradation of fiber, maybe because of microbial action, ... Extracted fibres are dried in hanging place by air. This treatment, Light and transmission electron microscope studies of naturally infected or inoculated staghorn sumac plants by Fusarium oxysporum f. sp. As the retting period increased the fineness of the fibre improved; however based on the tenacity (0.468 N/tex) and modulus (50.23 N/tex) a 25-day retting period was found to be optimum in this present study. The jute fibre comes from the stem and ribbon (outer skin) of the jute plant. : Retting of green jute ribbons (Corchorus capsularjs var ribbons An 7 days, rrjchoderma and Qurvujana took longer period of time (11 days) and other fungi showed insignificant progress of retting (Table IL Fiber strength of After bundles of jute are. As the current method of retting operation was carried out under aerobic condition, the emission of green house gas doesn't arise. rice, wheat, maize, sunflower and mach more. 2003;Munshi and Chattoo 2008). Jute Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. The lining itself generally did not label for cellulose or chitin. After the retting process, stripping begins. Among the two transgenic plant types one exhibited an increase in cellulose content and concomitant improvement of glucose release. Mostly, raw materials are being sourced carefully in terms of its decomposition after use but its cultivation and processing stages should be controlled as a manner to ensure that environment is being taken care of. Basic methods include dew retting and water retting. Ribbon retting … On the other hand, increased lumen diameter and a decreased cell wall thickness were observed with the decorticated and water retted bast fibers.
