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.展开更多
食酸假单胞菌(Pseudomonas acidovorans)菌株能过量生产赖氨酸,并且含有对反馈抑制不敏感的门冬氨酸激酶。用带有该菌株 DNA 片段的质粒转化抗乙基硫氨酸且过量生产蛋氨酸的大肠杆菌(Escherichia coli)突变体,获得的转化子同时过量生产...食酸假单胞菌(Pseudomonas acidovorans)菌株能过量生产赖氨酸,并且含有对反馈抑制不敏感的门冬氨酸激酶。用带有该菌株 DNA 片段的质粒转化抗乙基硫氨酸且过量生产蛋氨酸的大肠杆菌(Escherichia coli)突变体,获得的转化子同时过量生产赖氨酸和蛋氨酸。展开更多
