Title: Enzymatic synthesis of Biopolymers: A review

Abstract:

Enzymatic synthesis of Biopolymers: A review Green technology is taking over the industrial applications all over the world. As this technology is eco-friendly, less waste generating, low water requirement, low waste water generation and more importantly single step and specific reactions. Similarly, this technology is also being incorporated in the conventional methods for generation of biopolymers such as guar gum, xanthan gum, tamarind kernel powder etc. The process which is being utilized for this production is the enzyme based fermentation. Modified guar gum finds a wide variety of application as rheology modifiers in food and petroleum industries. Enzymes usually provide the efficient and very convenient method for modifying the structure of guar. High sugar containing media is also being fermented using different strains that can lead to high yield of xanthan gum. Tamarind kernel powder is also being modified using enzyme based processes as it finds a wide variety of application in food industries as a stabilizer, textile industries for printing the polyester fabric, in medical field also as a stabilizer in ointments and coating agents for tablets and in other industries such as leather industries, in pet food, paper industries and brick industries. The main enzymes being used in modifications of biopolymers are arrow mannanase, α-galactosidase etc. In this paper, we will be discussing about the previous reports in enzymatically modified biopolymers, current trends and future applications of the same. Key words: Green technology, biopolymers, fermentation, arrow mannanase, αgalactosidase
