It is obtained from the bark of plant through microbial retting process. Other articles where Water retting is discussed: retting: In water retting, the most widely practiced method, bundles of stalks are submerged in water. Depending on demand, price and climate, the annual production of jute and allied fibers in the world remains around 3 million tonnes. The contribution of the jute sector to the economy of Bangladesh is enormous. Jute (Corchorus capsularis and C. olitorius), Kenaf (Hibiscus canabinus) and Roselle/Mesta (Hibiscus sabdariffa) constitute very important fibre and cash crops of the world (Ali, 1990 and 1992).Total global production, about 3 million tons, of jute/kenaf, are harvested per ha. This paper is the first published report that a strain of B. polymyxa is capable of retting jute… • These fibres are extracted from the cellular and woody tissue of stem by a process of natural decomposition called retting. PPT – Opportunities and Constraints in adopting Technologies for Improving Jute production PowerPoint presentation | free to download - id: 2a503-ZjAyY. luteus were isolated and their action on jute stems studied. International Biodeterioration 27 (1990) 223-235 Enzymatic Retting of Jute Ribbons S. Majumdar, A. This study aims at focusing the effect of jute water-retting process on aquatic lives and hence developing a pilot-scale treatment process. Pectinolytic microorganisms are also responsible for retting, the central step in the textile production of vegetal fibres, such as flax, hemp, ramie and jute. Jute: Retting Process Jute: Fibre Extraction Jute: Fibre washing and drying RAMIE FIBRE Ramie is one of the oldest fibre crops, having been used for at … different types of retting processes used for bast plants such as hemp, jute, flax, and kenaf, with an emphasis on kenaf. Retting time must be carefully judged;… 48.6%. Retting is a microbial process that breaks the chemical bonds that hold the stem together and allows separation of the bast fibers from the woody core. Jute retting impacted lower native fish diversity indices like Shannon-Wiener index values (1.94 to 2.68) clearly indicated poor to moderate pollution status of the transitory water body in that area during monsoon in particular and throughout the year in general. Of these, 169 isolates have been purified and characterized. Keywords: Jute retting, fibre, accelerated retting, quality fibre, microbial retting Jute, also known as Golden fiber, is an internationally traded major commodity originating primarily from two developing countries-Bangladesh and India. megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. In Bangladesh, Jute is a vital sector from economical, agricultural, industrial, and commercial perspectives. polymyxa, five strains ofB. These fibers are strong and can be made into long threads and hence are very durable in carrying the heavy weight easily. Attempts were made to evaluate changes in the physicochemical parameters of water caused by jute retting, and their impact Jute fibers are separated from the stems of jute plants by retting process. This technique has been found easier and cost effective for jute retting by the jute growers in India. Jute fibre is the second most important fibre next to cotton. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. ... and the bundles submerged in water for retting. Abstract BBS.2008. While there are a few different botanical varieties of jute, one of the main species used to make jute fabric is Corchorus olitorius (white jute). The two tradition- In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. 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. B. Kundu, S. Dey & B. L. Ghosh Indian Jute Industries' Research Association, 17 Taratola Road, Calcutta 700088, India (Received 3 May 1990; revised version received 7 September 1990; accepted 27 September 1990) ABSTRACT Commercial enzyme preparations, viz. • They are cemented together with non cellulosic material to form continuous strand that may run the entire length of the plant stem. Bacteria capable of retting jute are present in pond water, in the soil of jute fields, and on the surface of jute plants. 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. Quantitative seasonal bio-monitoring of phytoplankton community composition with relative abundance and its diversity indices was carried out in this study from April 2013 to March 2014 to assess water quality and the impact of jute retting on phyto- Jute is a natural fiber that is mainly grown across West Bengal in India and in Bangladesh with some also grown in Myanmar, Uzbekistan, Thailand and china. 1. Abstract. BAST FIBRES • Bast fibres come from the stem of the plant. The plate count of the water was 3.5 x 106 bacteria/ml, more than ten times that of normal pond They probably enter stems over the whole surface through stomata, as well as through cut ends and leaf scars, after immersion for retting. Introduction. Jute is a product oriented commercial fibre obtained from the outer part of a jute plant. Jute is the common name given to the fiber extracted from the stems of plants belonging to the genus Corchorus, family Tiliaceae. * Jute has a decreased strength when wet, and also becomes subject to microbial attack in humid climates.
