Potential of probiotic bacteria to improve silk production: Boosting the Sericulture Industry in Northeast India

Silkworms' Gut are home to various microorganisms, including viruses, fungi, and bacteria. Bacteria are the most prevalent and varied group, with more than 100 species known to exist. These bacteria are members of several phyla, such as Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes. A wide variety of beneficial bacteria are found in the gut of silkworms. Probiotics mainly influence some aspects of the immune system and gut health by interacting with the complex community of intestinal bacteria known as the gut microbiota. Certain bacteria produce essential vitamins, amino acids, and other nutrients, while others help break down dietary fibres. Silkworms are an invaluable model organism for gut microbiota research due to their significance in ecology and economy. The present review discusses the diversity and functions of bacteria in silkworm digestive tracts and explores potential applications of these microbes in other sectors of the economy. The findings of this study have highlighted the importance and potential of silkworm gut microbiota, as well as the prospective applications of these microbes in the future to enhance silkworm health and resistance to illness. Thus, comprehending the relationships between silkworms and the bacteria in their stomachs may offer fresh perspectives on the biology of these significant insects and open the door to the creation of innovative methods for increasing silk production.
