0000074343 00000 n Retting of jute is done by Clostridium butyricum. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. 0000000016 00000 n Retting of jute is done by Clostridium butyricum. 2008;56:270–282. Breakthrough in Jute Retting by ICAR – CRIJAF through Genome Sequencing of Microbes of Microbial Retting Consortium India is the largest producer of raw jute and jute goods in the world, contributing about 60% of the global production and providing livelihood support to about 5 million people in farming, trade and industry. %PDF-1.5 %���� Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality. Retting time reduced from 18-22 days to 12-14 days with about 10% higher fibre recovery. Abstract BBS.2008. 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. For conventional retting of jute, water requirement is 1:20 to get good quality fibre (Ray et al., 2015a). Linen most useful: perspectives on structure, chemistry, and enzymes for retting flax. Bacterial retting was done in troughs at a temperature of 30 ± 2°C. FAO Agriculture Organization of the United Nations, Rome, Italy, pp 1–5 (1985). It is obtained from the bark of plant through microbial retting process. The water, penetrating to the central stalk portion, swells the inner cells, bursting the outermost layer, thus increasing absorption of both moisture and decay-producing bacteria. It is one of the largest sources of lignocellulosic bast fiber which is extracted from plants by a natural microbial process known as retting. subtilis, three strains ofB. The genome sizes of these strains are ~3.8 Mb with 3729 to 4002 protein-coding … Please enable it to take advantage of the complete set of features! USA.gov. Jute fibre is the second most important fibre next to cotton. The in-depth genomic analysis significantly revealed three different species of Bacillus constitute the consortium strains. iii. Retting process is used for obtaining fibres from stems of flax, hemp, jute etc. The repeated retting of jute and mesta in the stagnant water of same natural retting tank lead to the production of inferior quality fibre unless the tank is recharged with fresh water after each retting. As the conventional whole plant retting does not suit the farmers in the water crisis situation, mechano-microbial retting technology has been developed which needs some more studies for commercialization.  |  Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Jarman, C. G. The retting of Jute. Retting operation was carried out for varying time period namely 10, 15, 20, 25, 30 and 35 days respectively. 0000003171 00000 n 2012 Dec 30;2013:186534. doi: 10.5402/2013/186534. This article focusses on the microbial retting of jute bast fibres under aerobic condition using sequencing batch reactor. Jute fibre is the second most important fibre next to cotton. 0000005741 00000 n 0000004681 00000 n However, under the mechano-microbial method, green bark containing the fiber bundles is extracted from jute stems by a mechanical device. doi: 10.3923/pjbs.2003.686.687. Dew Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Among them, 144 isolates have been selected on the basis of extra cellular enzyme activity of these three enzymes. trailer Majumder A, Bairagya MD, Basu B, Gupta PC, Sarkar S. Sci Total Environ.

Biochemical Prospects of Various Microbial Pectinase and Pectin: An Approachable Concept in Pharmaceutical Bioprocessing. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. Basic methods include dew retting and water retting. For this reason jute is popularly called the "golden fiber" of Pakistan. 193 0 obj <>stream 16 s ribosomal gene sequencing analysis identified 2 phyla- Firmicutis (80.55%) and Proteobacteria (19.45%). 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 ii) Retting of green ribbons with microbial consortium. megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. -, Das B, et al. 1. <<603741E513CD7A43A3C047EABF18AC1C>]/Prev 610941>> The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. Retting is facilitated by anaerobic butyric acid bacteria such as Clostridium botulinum, Clostridium tetani and Clostridium perfringens. Anaerobic bacteria and aerobic microorganisms mostly mediate conventional retting of jute. Ali MH, Samad MA, Sarker NN. doi: 10.1007/s00248-007-9345-8.

To check the synergistic and antagonistic effect 10 selected isolates were tested in 167 different combinations. The ‘Jute ICARE’ interventions have resulted in enhancing the quality and productivity of raw jute and increasing income of jute farmers by Rs 10,000 per hectare, it added. Comparison of mean pectinase, xylanase and cellulose activities of 10 representative individual isolates with 3 selected bacterial consortia. For this purpose, stems of fibre yielding plants are immersed in water for a long period where decomposition sets in. To investigate the presence of microorganisms during the process of jute retting, full-cycle rRNA approach was followed, and two 16S rRNA gene libraries, from jute-retting locations of Krishnanagar and Barrackpore, were constructed. on the environmental quality of water: a case study. xref Nearly 80,000 farmers are engaged in jute cultivation in Assam and the annual production of jute fibre is 1.3 lakh tonnes.

It is obtained from the bark of plant through microbial retting process. Relative distribution of 14 species found in the 16S rRNA gene sequences analysis of jute-retting water. Yellow to red color indicates lowest to highest enzyme activity. NIH It’s easily and widely popularized due to property that it … During the storage of fish, dynamic primary changes are taking place in numerous parts of the fish, including the eyes, skin, gills and muscle characteristics of the fish. Retting is the process of extracting fibre from a plant's stem and one way of doing so is the use of micro-organisms and moisture.
