Species

The type species Gemmatimonas aurantiaca strain T-27T was isolated from activated sludge in a sewage treatment system in 2003. It is a Gram-negative bacterium able to grow by both aerobic and anaerobic respiration.

The second cultured species was Gemmatirosa kalamazoonensis gen. nov., sp. nov. strain KBS708, which was isolated from organically managed agricultural soil in Michigan USA.

The third cultured species Gemmatimonas phototrophica strain AP64T was isolated from a shallow freshwater desert lake Tiān é hú (Swan Lake) in North China. A unique feature of this organism is the presence of bacterial photosynthetic reaction centers. It probably acquired genes for anoxygenic photosynthesis via horizontal gene transfer. G. phototrophica is a facultative photoheterotrophic organism. It requires the supply of organic substrate for growth, but it may obtain additional energy for its metabolism from light.

Longimicrobium terrae strain CB-286315T was isolated from a soil sample from a typical Mediterranean forest ecosystem located in Granada, Spain. Due to this large phylogenetic distance from other cultured Gemmatimonades, it established a novel class named Longimicrobia.
