Description and significance
Members of the genus Photobacterium are common bacteria in marine environments. Photobacterium profundum is a newly discovered species that was isolated from sediment of the Ryukya trench off of Japan. It is barophillic and can survive under high pressures. It is a Gram-negative rod capable of growth between 4oC and 18oC (optimal at 10oC) under atmospheric pressure.
