Question

Retting of fibre is caused by
Clostridium tertium
E-coli

C.acetobutylichum
C.tetani​

Answer 1

Answer:

Explanation:

Retting is the process to dissolve pectin from the fiber bundles and separates the fibers from stems by the involvement of microbial activity in the presence of moisture. Clostridium has been found to play an important role in the process by hydrolyzing the pectin in the jute as it produces pectinase enzyme. Thus, the correct answer is option B

Answer 2

Answer:

(d)

Explanation:

Retting is facilitated by anaerobic butyric acid bacteria such as Clostridium botulinum, Clostridium tetani and Clostridium perfringens. These bacteria primarily decompose the plant pectin thus, freeing the fibres.
