Once considered a p In the method, a nitrogen fixing bacteria is added to the retting process to degum the gum or pectin from the fiber. 8 0 obj Alternatively, retting can be accomplished with the additions of chemicals, such as alkali (e.g., NaOH) or oxalic acid. Retting. Please update your bookmarks accordingly. Regardless of the harvest period, identical evolution of the fibres’ properties was observed during retting. 2 ) The process of retting = Water Retting = The most important types of bacteria involved in retting process are spore forming bacilli, penicillium sp. The dew retting process is weather dependent and time-consuming, so it is usually replaced by other methods. Retting, process employing the action of bacteria and moisture on plants to dissolve or rot away much of the cellular tissues and gummy substances surrounding bast-fibre bundles, thus facilitating separation of the fibre from the stem. The retted stalks, called straw, are dried in open air or by mechanical means, and are frequently stored for a short period to allow "curing" to occur, facilitating fibre removal. bacteria [pl. The smaller the cut size, the shorter the retting time. Bacteria were isolated from a coconut husk retting ground, a mangrove swamp, a free flowing backwater system and seasonal and perennial aquaculture ponds. Because these bacteria can create their own energy, they are classified as autotrophs. Dew Retting. Click here to get an answer to your question ️ 8. The process is easy but the trick is to know when the fibres are retted. In order to crush the decomposed stalks, they are sent through fluted rollers which break up the stem and separate the exterior fibers from the bast that will be used to make linen. etc. The plant fiber must first be broken down into a useable medium. This is a process which uses bacteria to decompose the pectin that binds the fibers together.

Retting is an essential step in production and plays a grcat part in determining the value of the product. 1) Meaning of retting = Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. The first way bacteria can obtain food is via photosynthesis. Discusses the function of bacteria in the digestive system. The enzymes which are produced by the ~_ 178 bacteria, are able to act best at a pH of 6.8 (Zahid,1973 ). Only these two organisms hydrolysed starch. Fibre quality in this process was found to enhance around two grades. Thisfact mayhave economic importance, and a process performed with this bacterium is currently under study in ourlaboratory. This may bring economic benefit to the farmers to the tune of ` 500-600 per quintal of jute fibre yield. Retting process is followedby chemical extraction of fibre. Dew-retted fibre is generally darker in color and of poorer quality than water-retted fibre. Question 2. The amino acids thus, liberated, are utilized by the plant world as nutrient. Retting Hemp Biomass. It is not unlikely that they bring about many changes in the process of rotting by their hitherto undiscovered properties. Tanning: In Tanning industry bacteria act upon the skin of animals and makes it soft and therefore it becomes pliable. Many of these methods detect bacteria by measuring oxygen levels or miniscule electrical disturbances that indicate the presence of bacteria. Debsharma (1946) reported that B. subtilis retted jute. [1], Tank retting, by contrast, employs vats usually made of concrete, requires about four to six days, and is feasible in any season. Retting (The process whereby naturally occurring bacteria and fungi, or chemicals, break down the pectins that bind the hemp fibers to be released. Binary fission is a very rapid process.
