WebThe MicroSEQ ID microbial identification system, based on comparative rDNA sequencing of the 16S region (for bacteria) or the LSU D2 region (for fungi), is a proven method for rapid and accurate microbial identification. Bacteria. The target for bacterial identification is the 16S ribosomal RNA (rRNA) gene sequence. WebBased on the shape of the cell, bacteria are classified into four main groups that are as follows: Coccus or cocci (spherical) Bacillus or bacilli (rod-shaped) Spirillum or spirilla (spiral) Vibrium or vibrio (comma-shaped) Further reading: Shapes Of Bacteria Eubacteria They are true bacteria.
