conversion of starch into simple carbohydrates, 

 such as dextrins and sugar by means of diastase, 

 bacteria in the shape of a club. 



a growth along the line of inoculation with toothed 

 or pointed margins. 



growth thin, veilly, unusually spreading, 

 drawn out, lengthened or extended, 

 thick walled spores formed within the bacterial 

 cell; i. e. typical bacterial spores like those in B. 

 anthracis or B. subtilis. 



smooth, having a margin destitute of teeth or 

 notches. 



growth composed of long, irregularly placed or 

 interwoven threads. 



applied to the morphology of bacteria, it refers to 

 thread-like forms, generally unsegmented; if un- 

 segmented, to be distinguished from chains (q. v.) 

 by the 'absence of constrictions between the seg- 

 ments. 



in stroke or stab cultures, a uniform growth along 

 the line of inoculation. 



fine hair-like extensions that propel certain kinds 

 of bacteria through liquids. 



resembling or consisting of flakes or separable into 

 flakes. 



containing small adherent masses of bacteria of 

 various shapes floating in the culture fluid, 

 having one color by transmitted light and another 

 by reflected light, 

 composed of small granules. 



a method of differential bleaching after gentian 

 violet, methyl violet, etc. The + mark is to be 

 given only when the bacteria are deep blue or re- 

 main blue after counterstaining. 

 clotted. 



obtaining their elemental atoms of carbon, oxygen, 

 hydrogen, nitrogen, sulphur and iron from organic 

 compounds. 



form of a funnel or inverted cone, 

 exhibiting changing rainbow colors in reflected 

 light. 



milk sugar. 



red indicates acid, blue indicates alkaline, 

 change of a solid into a liquid. 



having the margin deeply undulate, producing lobes, 

 (see undulate.) 



more than two diameters in length, 

 glowing in the dark, phosphorescent, 

 the temperature above which growth does not take 

 place. 



growth thin, like a membrane. 



temperature below which growth does not take 

 place. 



having power of motion. 



colonies having the radiately filamentous appear- 

 ance of mold colonies, 

 liquefaction in the form of a turnip, 

 not having chromogens or coloring matter, 

 impervious to light.
