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