Abstract
The wide utility and catalytic efficiency of microbial pectinase in various industries has greatly increased its global demand. Among the natural sources of pectinases, microbial pectinases are used frequently for its ease of production and unique physicochemical properties. Yet similar to other industrial enzymes, pectinases also face the constraint of thermo-tolerance and low yield in its economised production. The current review addresses the various strategies adopted to meet the high yield and thermo-tolerance of pectinases as well as the various attempts made in the field of pectinases to its improved production and better catalytic efficiency. The utilisation of natural as well as recombinant microbial sources, metagenomic approaches, metabolic engineering, site directed mutagenesis and media engineering techniques adopted in the field of pectinases have been discussed. The significance of pectinases in various industries is depicted by enlisting its applications. To the best our knowledge the current review is unique being the first attempt to compile the recent advancements in the field of pectinases.
