An Insight into Production Strategies for Microbial Pectinases: An Overview

With the advancement of biotechnology, there is an increase in the creation of environment-friendly and long-lasting bioprocesses for enzymes. Microbial enzymes offer exceptional activity, specificity, and selectivity, making them promising biocatalysts for a variety of exciting applications, such as biocatalysis, biosensors, and biomedicine. Due to their minimal chemical usage and lack of harmful by-products, these are green tools for sustainability. The main limitations at large-scale enzyme-catalyzed bioprocesses include high operational costs due to the restricted stability and reusability of the enzymes. Enzymes are fundamental components of the biosynthetic pathways used in the creation of many different bioproducts. Utilizing downstream processing techniques targeted at enzyme recovery and purification, various production methods for microorganisms are used. The use of microbiological sources, their improved strains, and downstream processing techniques with membrane augmentation can be used to improve the concentration, purity, and percentage of enzyme recovery. Microbial pectinases have a wide range of industrial applications, including the degumming and retting of plant fibers, extraction of oils, fruit juice clarification and wine production, fermentation of tea and coffee, bioconversion of wastes, and protoplast fusion technology. Pectin-rich biomass can be a prominent source for mining these potential enzymes. The chapter reviews sources of microbial pectinases and their production methods based on fermentation. The bioprocessing of microbial pectinases using bioreactors-based large-scale productions, improved production strategies utilizing resonance surface technique, and pectinolytic immobilization are key components of the present study.
