Question

For retting of jute the fermenting microbe used is
A. Mesophilic bacteria
B. Butyric acid bacteria
C. Helicobacter pylori
D. Streptococcus lactis

Answer 1

Hint: In retting we measure the activity of microorganism and dampness on plants to break down or decay away a significant part of the cell tissue and sticky substances encompassing bast fiber packs, accordingly encouraging partition of the fiber from the stem.

Complete answer:
Retting is a primary test that is looked at during the preparation of the best plant for making long fibers. The conventional techniques for isolating the long bast filament are by dew and water retting. The two techniques expect 14 to 28 days to debase the pectic materials, hemicelluloses and lignin.
Even though the filaments delivered from water retting can be high caliber, the long length and contaminated water have made this technique less alluring. There are various elective strategies, for example, mechanical decortications, synthetic heat and enzymatic medicine have been accounted for this reason with blended discoveries.

Hence, the correct answer is option (B).

Additional information:
Enzymatic retting has clear favorable circumstances over retting measures by having altogether shorter retting time and adequate quality strands, however, it is very expensive Butyric corrosive microbes helps in the retting of jute fiber.
Here are recorded various kinds of retting measures utilized for bast plants, for example, hemp, jute, and kenaf, with an accentuation of kenaf. Among the bast fiber crop, kenaf has a few points of interest, for example lower cost and higher yield and most prominent adaptability as a rural asset, over the other bast strands. The strands made from kenaf utilizing compound retting measures are a lot of cleaners however low in rigidity.

Note: Several microorganisms, both aerobic and anaerobic are associated with the retting of jute. Not all the microorganisms separated from retted jute are liable for the cycle.
