【Abstract】 A sabin P301 of Gram negative purple nonsulfur bacterium was isolatedfrom the ditch’s mud collected in Fuzholl. Fujian. The cells are red-shaped.Mulhplication occur by budding without stalk formation. Growth optimum PH is 5.05.7. No growth faCtors required. The cells contain baCteriochlorophyll a Thephotosynthehc membrane system consistS of Palallel lamellae. According tO Bergey’sManual of Detendnahve Bacteriology, sib ed. (1974) and 9th ed. (1994),the stainwas identified to be Rhodopseudomonas acidophila. But on the side of enzyme activity,uhlization of orgboc substrates and others the strain some differ from the type straindescribed by N Pfennig (1969). Therefore the stain P301 was idenhfied to beAnodopseudomonas acidophila var. fujianensis n. var.更多还原
