Microbial DNA barcoding: Prospects for discovery and identification

Abstract

DNA barcoding is a technology used for the identification of any biological species by sequencing obtained through amplification of DNA. Here, we seek a standardized protocol along with the choice of markers used for different microbial species: bacteria, fungi, algae, plants, and animals. Various projects, consorts, tools, and databases have been discussed. With the advancement of technology, the future scope and applications have also been identified with an argument on the limitations along with the concept of universality on the DNA barcoding.
