Morphology Ensifer adherans
CELLULAR  
Staining . Gram-negative but may stain poorly
Morphology Rods 0.7-1.1 x 1.0-1.9 um, occurring singly or in pairs.
Motility Motile by means of a tuft of three to five flagella that are attached subterminally.
Specialized structures Attaches endwise to various Gram-positive and Gram-negative host bacteria. It may cause lysis of the host bacterium..
Division Reproduction by budding at one pole of the cell, with the bud then elongating to give asymmetric polar growth . Separation of cells is by binary fission
COLONIAL  
Solid surface Colonies 10-15 mm in diameter develop on 0.1x heart infusion agar and are greyish white, convex, slimy moist, opaque and circular with undulate margins. They may appear almost translucent due to excessive slime production

Growth Parameters Ensifer adherans
PHYSIOLOGICAL  
Tropism chemoheterotroph
Oxygen Aerobic; does not grow anaerobically in the presence of light
pH optimum pH 6
Temperature Optimal growth occurs at 27`C; good growth at 20 and 37`C. Not heat-resistant
Requirements Growth is inhibited by 4% NaCl but not by 2% NaCl. Grows well on most media. Definite but slow growth on soil extract agar and 1.5% Noble agar in distilled water. Agar not hydrolyzed. Utilities a variety of organic carbon sources.
Products Nitrate and nitrite are reduced. Nitrification is negative for ammonia and nitrite. Grows on pure gelatin without hydrolysis
Enzymes Weakly catalase-positive The metabolism of glucose and galactose is oxidative
Unique features Non obligate predator that attaches endwise to various living Gram positive and Gram negative host bacteria Host cells not required.
ENVIRONMENTAL  
Habitat isolated from soil
Lifestyle Non obligate predator that attaches endwise to various living Gram positive and Gram negative host bacteriaHost cells not required. Attachment to and lysis of bacterial cells occurs naturally in soil and in vitro with pure cultures
