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