GENERAL SYSTEMATIC BACTERIOLOGY 357 



Saprophytic, growing vigorously in saccharine solutions. Cells in pairs or in 

 true chains. In presence of certain carbohydrates large, lobed, gelatinous masses 

 of zoogloeae are formed. Fermentation powers high, acid being produced in 

 dextrose, lactose and saccharose. 



Vuillemin (1913, p. 520) concludes that Leuconostoc should be 

 treated as a section of the genus Streptococcus, 

 Buchanan (1917, p. 611) states: 



Saprophytic, usually growing in cane sugar solutions. Cells in chains or pairs. 

 Forming large zoogloeal masses when grown in sugar solutions. Produces acid 

 actively from carbohydrates. Some types at least are Gram-negative. 



The type species is Leuconostoc mesenteroides (Cienkowski) Van Tieghem. 



Winslow et al. (Committee American Soc. of Bact. 1920, p. 206) 

 give the following diagnosis: 



Saprophj^tes, usually growing in cane sugar solutions. Cells in chains or pairs, 

 united in large zoogloeal masses. Some types at least Gram-negative. 

 Type species, L. mesenteroides (Cienkowski) Van Tieghem. 



Bergey et al. (1923, p. 45) follows the Committee, including the 

 genus as the second in the tribe Streptococceae. 



Leucothrix. A generic name adopted from Oersted (1844, p. 44) 

 by De Toni and Trevisan (1889, p. 932) to serve as a subgenus of 

 Leptotrichia Trevisan. The type species is Leptotrichia (Leucothrix) 

 mucor (Oersted) Trevisan. The subgeneric description given is simply 

 "Marinae, majores." Leucothrix was previously used by Trevisan 

 (1879, p. 138) as a synonym in part of Beggiatoa. 



Lineola. A name used by von Baer (1827, p. 748) in the following 

 sentence: 



Die Reihe fiir die Thiere des Typus mit vorherrschender Langendimension 

 beginnt mit lebendigen Faden; Lineola, (so mogen die einfachsten Vibrionen 

 heissen), repriisentirt sie unter den Protozoen. 



Lipobacter. A generic name proposed by de Kruyff (1906. p. 1) 

 for bacteria which hydrolyze and oxidize fat. These organisms are 

 common in the soil, hydrolyzing fat to glycerine and fatty acids and 

 later oxidizing each of these products. 



If these organisms are deserving of generic recognition, this name 

 possibly would be valid, although his species were numbered only and 

 not named. 



Liquidobacterium. A generic name proposed by Orla-Jensen (1909, 

 p. 337) for organisms of the Proteus type. He says:
