So, ribbon retting is a great promise to produce high quality jute fibre in one hand and a more eco-friendly measure on the other. In addition, the inoculation treatment with P. longanae significantly promoted the activities of CWDEs including pectinesterase, polygalacturonase, β-galactosidase, and cellulase. Jute is one of Bangladesh’s main cash crops. Agricultural practices and seed varieties used in Indian subcontinent is also widely different from those of Philippines. Samples were exposed to outdoor conditions to evaluate their resistance against biological deterioration. Retting and extraction processes have a profound effect on the quality of fiber and on the cost of fiber production. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. If ribbons are retted it is called ribbon retting. Retting Environment • Jute assimilates about 5.8 ton CO2 from the atmosphere in its lifetime (Rahman and Bala, 2009). residues every year (MNRE, 2016) which may either burnt in the field that produces green house gases ... For bacterial degumming, some researchers have studied the screening and community structure of degumming bacterial strains of jute (Banik et al. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. On the other hand, increased lumen diameter and a decreased cell wall thickness were observed with the decorticated and water retted bast fibers. Indian agriculture is producing very large quantity, approximately 500 million tonnes of crop i) Mechanical extraction of green ribbons through either power operated bast fibre extractor suitable for jute, mesta, sunnhemp and ramie or manually operated jute fibre extractor and. are mostly recommended in the jute growing countries. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. The mixed bacterial culture in combination with urea produced stronger, finer and brighter coloured jute and kenaf fibre in comparison to uninoculated control. The retting process consists of bundling jute stems together and immersing them in slow running water. Demerits of mechano-microbial retting 5.2. Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process. Jute retting process is one of the important responsible factors for quality of jute fiber. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials. Pectinolytic enzymes were found to ret green jute ribbons within 48 h, producing fairly good quality jute fibres (Majumdar et al., 1991). different agriculture based biowaste sources. Advantages of Ribbon Retting • Lesser amount of water is required for retting. Both over retting and under retting which are very difficult to control causes production of low grade jute fibre. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. The retting process consists of bundling jute Jute is a rain-fed crop and its cultivation is concentrated in Bangladesh, India, China, and Thailand. This improved retting technology can be adopted in industrial scale for the production of quality jute fibre in a controlled condition in reduced water quantity without polluting the environment. Composition of the lignin building blocks was found to alter and this alteration resulted in a pattern, different from other plants where the same genes were manipulated. Eventually resulting in development of disease development and fruit decay in harvested longans during storage at 28°C. Though they are very effective as far as their end application is concerned, the availability of those fibres in the near future may get reduced due to depletion of natural resource, i.e., petroleum oil. Jahan et al. Natural fibre based composites are under intensive study due to their eco-friendly nature and peculiar properties. Various reports are available regarding the effect of microbial inoculation on hemp, flax, ramie and kenaf fibre quality (Candilo et al., 2010;Tamburini et al., 2003;Basu et al., 2009;Yu and Yu, 2007). Indian Agriculturist 31 (I), 49 Á/52. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. Whole sterns were retted for 14 days and ribbons for 9 days. would be the product of extraction of all possible agriculture based bio-waste, crop residues, stalks, straw etc of Higher pectinolytic bacterial isolates were predominant in the later stage of jute retting. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. As jute made products are getting popular worldwide, steps are to be taken to comply with the demand of customers and conservationists. Enzymativ all volumes and issues. There are two types of retting: stem and ribbon. The ditches may be filled with clear water from tube well or from any other water sources. Throughout training sessions there were instances where technology was introduced without attention to its usefulness for farmers and fisher groups. The degummed and bleached fibres were then successfully converted into textile quality thread of 90 tex through suitable mechanical processing system. The retted fibres were then degummed and bleached for better processibility and aesthetic look. ... One percent alkali solubilities of jute fiber and jute stick in both retting processes were almost similar (31% for jute stick and 21% for jute fiber). This indicates that the piling microbes might play a significant role in remoling residual pectin from the fibre during piling of jute. Merits of in-situ 6. This crop residue are one of the biggest component of all agriculture bio waste which either left in field or its large amount, 140 million tones is burnt on the field primarily to clear the remaining straw and stubble after the harvest. Ribbon retting has the following advantages over conventional retting: (1) It requires lesser volume of water, (2) it is faster, (3) it produces lesser environmental pollution, and (4) it produces improved quality fibre. 16 s ribosomal gene sequencing analysis identified 2 phyla- Firmicutis (80.55%) and Proteobacteria (19.45%). Paul, N.B., Bhattacharyya, S.K., 1978. Improved method of upgrading barky jute at farmer's level with Penicillium corylophilum Dierckx. ultimately or left in the field unutilized. is ideal. 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. Although it is an integral part of the plant cell, presence of lignin considerably reduces the quality of the fiber of fiber-yielding plants. Microbial inoculation produced remarkable improvement in jute fibre strength (26.62–28.91 g/tex) and fineness (2.76–2.92 tex) over control. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Ribbon retting of jute—a prospective and eco-friendly method for improvement of fibre quality. Some jute was brought to Dundee, Scotland where eventually a process was designed to spin jute yarn in large volumes. either in a water solution or sprinkled directly in the layers of the jute bundle in jute jaks. 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. Jute became an important export from the countries that produced it. Transgenic generations, analyzed through Southern, RT-PCR and northern assays showed downregulation of the selected genes. Copyright © 2003 Published by Elsevier B.V. https://doi.org/10.1016/S0926-6690(02)00097-3. Therefore, Bangladesh Government has introduced ribbon retting method in different areas of the country to ease peeling of jute fiber. In contrast with the ribbon retting of jute, ... Due to this invention, retting microorganism gets more surface area of inner side of the bark with respect to conventional method (Banik et al., 2007). Jute is a rain-fed crop with little need for fertilizer and pesticides. : 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 The variation of papermaking properties of the produced pulp onretting process was insignificant. In the retting tank, use of pectinolytic microbial inoculums could be introduced to improve quality of fiber and reduce the time of retting, ... Additionally, polluted water containing chemicals as pesticides and fertilizers increases the risks. The presence of theses acids in retting water may lead to the reduction of pH, ... To get the average lignin value of a plant, only the mid-section (~16 cm) of the stem was used in this study. In addition, pineapple fiber is completely/partially biodegradable and recyclable, cheap to produce, and easy to make. A slight increase in fiber density was observed for NaOH and benzoate retted bast fibers indicating cell wall densification. Depending on samples, fibre strengths Stelometer are equal to or considerably greater than dew retted ‘cottonized flax or typical cotton fibres. You can request the full-text of this article directly from the authors on ResearchGate. Our results suggested that the bio-processing presented herein contributes to the possible development of a new means of bamboo bio-processing that can be regarded as a primary process to separate fibre bundles from non-cellulosic tissue in the culm. The microbial enzymes predominately pectinases are becoming popular for retting of fibers owing to the fact that it results in high quality fiber, save time and is also ecofriendly. Basic methods include dew retting and water retting. Some of this material labelled for pectin, often in association with tyloses, as did other opaque matter in paratracheal, Access scientific knowledge from anywhere. In contrast with the ribbon retting of jute (Banik et al. This treatment, Light and transmission electron microscope studies of naturally infected or inoculated staghorn sumac plants by Fusarium oxysporum f. sp. In ribbon retting, barks are removed from jute in the form of ribbon. Consideration is given to external loading and molecular characterization and crystallography of pineapple fiber to better understand its mechanical and thermal behavior. ... Ribbon retting reduces the requirement of water from 1:20 to 1:10 substrate liquor ratio, decreases the length of retting time and controls the level of environmental pollution to almost onefourth in comparison to that of whole plant retting. It is obtained from the bark of plant through microbial retting process. In this paper, effect of ribbon rettingon the chemical properties of jute fiber and jute stick was carried out. The retting experiment was carried out in artificial plastic retting tanks during 2009 and 2010. This technique involves the application of microorganisms and/or enzymes. The retting process consists of bundling jute stems together and immersing them in low, running water. L6 (GQ891097), Bacillus pumilus strain EK-17 (GQ891098), B. pumilus strain Geo-03-422 (GQ891103) and B. pumilus strain IK-MB12-518F (GQ891105). 2003), during jute degumming process of bacterial strain DCE-01, within 12 h, pH is kept acidic while ORP kept being greater than 0 namely under aerobic status, at 15 h, pH Retting may be defined as the separation of bast fibres from the core tissues of the stem. In contrast with the ribbon retting of jute (Banik et al. India is the highest producer of Okra in the world, but after okra harvesting, the stem mostly remains underutilized. Other thin elements, often enclosing opaque material, vesicular structures, or occasionally particles of riboso- mal appearance were also delineated by similar but frequently infolded bands. This study concludes that comanagement can facilitate local capacity but in order to realize the full potential of this approach we must address the issues of inappropriate technologies for training, the financial barriers to fishers with low cash income, and uneven power relationships among stakeholders, to create an enabling environment for effective modern governance of the fisheries commons. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. Similarly labelled opaque bodies occasionally occurred on vessel walls and lumina. Traditional processes are outdated which should be modified according to the technological advancement. The retting process consists of bundling jute stems together and immersing them in slow running water. Cultivation is dependent on the climate, season, and soil. In actual practice the fungal … Tables of content are generated automatically and are based on records of articles contained that are available in the TIB-Portal index. Synthetic hydrocarbon-based biostable polymeric fibres contribute about 60% of the global fibre production. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. In-situ retting of jute & mesta with microbial formulation 5.2.1. 5 Proofreading When you feel confident about your revisions, move on to the last writing process step: proofreading. The ribbons are coiled and then allowed for retting in water. A number of other alternative methods such as mechanical decortication, chemical, heat, and enzymatic treatments have been reported for this purpose with mixed findings. Data book on jute. The residual gum content and weight‐loss ratio obtained from experimental results were consistent with those given by the model, and the average errors between them were 2.15% and 4.3%, respectively. Effect of efficient pectinolytic bacterial isolates on retting and fibre quality of jute, A proposal of sustainable and integrated plant for jute fiber extraction in an eco-friendly manner, Chemical characteristics of ribbon retted jute and its effect on pulping and papermaking properties, Bio-degumming technology of jute bast by Pectobacterium sp. The bacterial isolates are mostly Gram-positive rods of the genus Bacillus and fungi mainly of the genera Aspergillus and occasionally Penicillium. The fibers are first extracted by retting. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water.
