**Abstract**

Efforts put in overriding the inulin abundant invader nastiest category I weeds are infeasible that lead into its impermanent confiscation. Hence, their heedful exploitation is obligatory. These invasive weeds have ample amount of inulin, which serves as a renewable, cheap raw substrate for inulinase production. Therefore, they have enticed intention of many researchers toward exploring more idiosyncratic inulinase producing microbial strains that utilize invasive inulin-rich weeds as substrate for fructose liberation. Plenteous industrial applications of inulinases have marked it distinctly crucial in recent biotechnological epoch. This review thus elaborates the literature on infused footprints embedded by the substituted low calorie healthy sweetener in new advancing fields.

### **1. Introduction**

Weeds are plants that grow luxuriantly in unsolicited places with no special assistance of human. These plants spread rapidly by shading abundant seedlings, making land unfit for agriculture, forestry, and livestock. Their characterized adaptability to extensive range of soils and weathers has proved a boon for their survival at any piece of earth. They also have capabilities of tumbling inherent plant ecosystems and fluctuating natural biota in injurious ways. Due to the competency of piercing and interchanging indigenous flora, majority of them are recognized as environmental weeds or exotic or noxious aggressive invaders [1].

Apart from this negative side, countless constructive purposes of weeds as a part of their control strategies have still remained unnoticed. Therefore, this research theme was needed to be explored and expanded. Consequently, when seen from a different standpoint, such weeds have high inulin in them. Thus, this work explores inulin-rich weeds as a veritable and bioconvertible resource for sugary wealth creation, using efficient inulinase producing microbes.
