Abstract
Enzymes are an indispensible component of metabolic processes that helps in maintaining soil and plant health. Innovative solutions associated with enzymes are essential for crop production by maintaining healthy soil conditions and helping to mitigate common problems associated with intensive agricultural practices. The chemical fertilizers pose a hazard for soil fertility and consequently for human health. Microbial solutions derived from plant growth-promoting microorganisms can replace or complement traditional fertilizers and pest-control solutions. There are various categories of microbial enzymes present in soil that promote plant health and growth such as phosphatase, catalase, oxidase, ACC deaminase, nitrate reductase, urease, chitinase, ligninases, and various hydrolytic enzymes. Additionally, plants treated with a bioinoculant with promising enzymatic activities could be the most effective approach for growth promotion of seedlings under axenic as well as field conditions. Hence, the employment of valuable microbial enzymes as an agricultural feed for larger crop production needs the selection of competent microorganisms with plant growth-promoting attributes. In the future, these enzymes can be overexpressed, optimized, and manipulated for maximum utilization of their performance.
