For retting of jute the fermenting microbe used is

Explanation

The fermenting microbe used for retting jute is not methanophilic bacteria, Helicobacter pylori, or Streptococcus lactis. The correct microbe used in the retting process is butyric acid bacteria. Here's an explanation of all the options and a summary: Methanophilic bacteria: Methanophilic bacteria are not used in the retting of jute. They are specialized bacteria that produce methane and are typically found in anaerobic environments, such as certain wetlands and the digestive systems of animals. Helicobacter pylori: Helicobacter pylori is a bacterium associated with stomach ulcers and gastritis in humans. It has no role in the retting of jute. Streptococcus lactis: Streptococcus lactis is a lactic acid bacteria used in the fermentation of dairy products, but it is not used in the retting of jute. Summary: Butyric acid bacteria are the fermenting microbes used in the retting process of jute. They help break down the pectin substances in jute fibers, facilitating the separation of the fibers from the plant's woody core. Methanophilic bacteria, Helicobacter pylori, and Streptococcus lactis are not involved in this specific industrial process.
