Wilson’s reasoning would put the total number of bacterial species at 100,000, probably a tenfold underestimate. Most environmental microbiologists believe that less than one-tenth of 1 percent of all bacteria can currently be grown in laboratories so that they can be identified. Microbial geneticist J.””
