FAMILY BACTERIACEAE 



639 



Source : Isolated by McCulloch and by 

 Burkholder from blighted iris leaves. 

 Habitat: Pathogenic on Iris spp. 



47. Bacterium albilineans Ashby. 

 (Ashby, Trop. Agr., Trinidad, 6, 1929, 

 135; Phytomonas albilineans JMagrou, in 

 Hauduroy et al., Diet. d. Bact. Path., 

 Paris, 1937, 326.) From Latin, produc- 

 ing white streaks. 



Description taken from Martin, Car- 

 penter and Weller, The Hawaiian 

 Planters' Record, 36, 1932, 184. . 



Rods: 0.25 to 0.3 by 0.6 to 1.0 micron, 

 occurring singly or in chains. Motile 

 with a polar flagellum. Gram-negative. 



Agar colonies: After 7 to 10 days, 

 minute transparent drops, moist, shin- 

 ing. Honey yellow to Naples yellow. 



Gelatin: No liquefaction. 



Milk: Growth, but no visible change 

 in the milk. 



No growth with ammonium salts, ni- 

 trates, or asparagine as a source of ni- 

 trogen. 



No growth in peptone water without 

 carbohydrates. Invertase secreted. 



Starch is not hydrolyzed. 



Optimum temperature about 25°C. 

 Maximum 37 °C. 



Distinctive characters: Differs from 

 Xanthomonas vascularum which produces 

 a large gummy type of colony, and which 

 is a very active organism biochemically. 

 The two pathogens also differ in the 

 type of lesion they produce on .sugar 

 cane. 



Source: Isolated by D. S. North (Co- 

 lonial Sugar Ref. Co., Sidney, N.S. 

 Wales, Agr. Rept., 8, 1926, 1) from white 

 stripe and leaf scald of sugar cane in 

 Australia. 



Habitat : Vascular pathogen of sugar 

 cane, Saccharutn officinarum.

 liave been described from diseased plant 

 tissues but may not, in some cases at 

 least, have been the cause of the disease.
