0 0. Jute fibre is chemically ligno-cellulose in nature. Still have questions? Get answers by asking now. It is a gram-positive butyric acid producing bacteria. Complete removal of pectin and polysaccharide gummy materials are necessary to obtain good quality fibre keeping the natural strength of cellulose. Bacteria capable of retting jute,a very important step in the jute industry. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. Three strains ofBacillus macerans, four strains ofB. Methophilic bacteria found in cold methane seeps forms a symbiotic relationship with deep-sea invertebrates. Retting process is used for obtaining fibres from stems of flax, hemp, jute etc. MICROBIAL RETTING Microbial retting consortium can be used either for ribbon or whole plant during water scarcity situation utilizing minimum amount of ground water. 1 decade ago. they are bacterial communities associated with the retting of jute. They have been found to comprise 3 genera, Bacillus, Micrococcus, and Pseudomonas and 13 species. For conventional retting of jute… For retting of jute the fermenting microbe used is [CBSE PMT 2005] A) Methophilic B) Butyric acid bacteria C) Helicobactor pylori D) Streptococcus lactin It is a gram-positive butyric acid producing bacteria. Retting of jute: Chemistry behind Anaerobic bacteria and aerobic microorganisms mostly mediate conventional retting of jute. Join Yahoo Answers and … luteus were isolated and their action on jute stems studied. They were classified in 3 genera, Bacillus, Micrococcus, and Pseudomonas and 13 species. 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. Ahmad (2008) isolated aerobic and anaerobic bacteria from samples of retted jute stems. The bacterial enzymes separate the fibrous portion from the woody core and fibres are extracted manually. Bacteria capable of retting jute are present in pond water, in the soil of jute fields, and on the surface of jute plants. They probably enter stems over the whole surface through stomata, as well as through cut ends and leaf scars, after immersion for retting. All bacterial isolates isolated from jute retting water do not have pectinolytic activity, but some important species among them shows this ability. Ask question + 100. polymyxa, five strains ofB. 0 0. For this purpose, stems of fibre yielding plants are immersed in water for long period where decomposition sets in. megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. Of these, 169 isolates have been purified and characterized. subtilis, three strains ofB. Anonymous. Title: Jute Retting: An Overview Author: Zakaria Ahmed and Firoza Akhter Subject: Journal of Biological Sciences Keywords: Jute, retting, bacteria, fungi 1976), resulting in the reduction of growth of retting bacteria compared to higher growth observed at initial and middle stage of retting. Retting of jute is done by Clostridium butyricum. Jute is one of the most versatile bast fibers obtained through the process of retting, which is a result of decomposition of stalks by the indigenous microflora. 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.
