Overview of Gram-Positive and Other Bacteria Bacteria has many phyla other than Proteobacteria,including -Gram-positive bacteria Large group of mostly chemoorganotrophs -Cyanobacteria Oxygenic phototrophs that have evolutionary roots near those of gram-positive bacteria -Phylogenetically early-branching phyla ·Such as Aquifex产液菌属 Other morphologically distinct groups CHEN FENG,MICROBIOLOGY,SJTU
