In India, sericulture has started thousands of years ago and over the years silk has become an inseparable part of Indian culture and tradition. It is also one of the highest employment providers by combining both agriculture and industry. India is the second largest producer in silk in the world and process the distinction of producer of all the 4 varieties of commercial silk namely, mulberry silk (Bombyx mori), eri silk (Samia ricini), tasar silk (Antheraea mylitta) and muga silk (Antheraea assamensis). Among these 4 varieties of silk produced, mulberry accounts for 75%, tasar 7%, eri 17% and muga 1% of total raw silk production. The major silk producing states in India are Karnataka, Andhra Pradesh, Tamil Nadu, West Bengal and Jammu & Kashmir. The raw silk production of mulberry silkworm shows increasing trend during the last decade due to development of high yielding mulberry varieties and silkworm breeds coupled with technological innovation in cultivation and rearing practices. Natural silk is unique with its own importance, elegance and luster, natural silk is comfortable to wear and good for health. Silk is resistance against too high temperature. The elegant feature of silk thread is due to its fine luster and soft touch.

Frequently Asked Questions
Why is mulberry cultivation important for silk production?
Mulberry leaves are the primary food source for silkworms (Bombyx mori). Mulberry silk accounts for 75% of total raw silk production in India.
What are endophytic bacteria?
Endophytic bacteria live inside plant tissues without causing harm. They can promote plant growth and protect against diseases from within.
How can bacteria promote mulberry growth?
Certain bacteria produce growth hormones, help in nutrient uptake, or suppress harmful pathogens in the soil (biocontrol).
What are the main silk varieties produced in India?
India produces four commercial varieties: Mulberry, Eri, Tasar, and Muga silk. India is the second-largest producer globally.
What is the goal of this dissertation?
The study aims to isolate and identify bacteria from mulberry plants that can act as natural biocontrol agents and growth promoters for sustainable sericulture.
