Microbial Life Database


The Microbial Life Database (MLD) is a project under continuos development to visualize the ecological, physiological and morphological diversity of microbial life. A database is being constructed including data for nearly 600 well-known prokaryote genera mostly described in Bergey's Manual of Determinative Bacteriology and published by the Bergey's Trust. Correction and additions come from many other sources. The database is divided by genera but we are working on a version by species. This is the current database v02 in Google Spreadsheets format. Below is a bubble chart of the number of species included in each of the microbial groups. You can click the graph to go to an interactive version with more details. If you want to contribute to this database please send an email to Prof. Abel Mendez.
