resembling the color of an opal, 

 the temperature at which growth is most rapid, 

 growth beset with small nipple like processes, 

 a kind of bacteria causing disease, 

 bacterial growth forming either a continuous or 

 interrupted sheet over the culture fluid, 

 covered with flagella over the entire surface, 

 rendering albumen of milk soluble by the action of 

 trypsin. 



lasting many weeks or months, 

 producing phosphorescence, 

 a fleecy or feathery growth, 

 at the end of pole of the bacterial cell, 

 prototrophic bacteria are those that can use elemen- 

 tal atoms of carbon, oxygen, hydrogen, nitrogen, 

 sulphur and iron. 



decidedly convex, in the form of a cushion, 

 very small, but visible to the naked eye; under one 

 mm. in diameter. 



culture containing only, one species of bacteria, 

 developing in 24 to 48 hours, 

 growth thick, with abrupt or terraced edges, 

 refers to the production of acid or alkali in culture 

 media by bacteria. Use -+- to indicate acid, to in- 

 dicate alkaline, and O no change, 

 removing oxygen from a chemical compound. 

 Refers to the conversion of nitrate to nitrite, am- 

 monia, or free nitrogen, and to the decolorization 

 of litmus. 



a curd produced by a lab ferment, not by an acid, 

 growth of an irregular branched or root-like char- 

 acter, as in B. mycoides. 



growth at the upper margin of a liquid culture, 

 adhering more or less closely to the glass, 

 long, more than two diameters in length, 

 wrinkled, 

 cane sugar. 



liquefaction in the form of an elongated sac, tubu- 

 lar cylindrical. 



an organism living on dead organic matter, 

 less than two diameters in length, 

 requiring 5 or 6 days for development, 

 bacteria growing in the form of a spiral, 

 growth extending much beyond the line of inocu- 

 lation, i. e. several millimeters or more, 

 cells containing endospores. 



the wall of a cell within which a spore has been 

 produced. 



the resting stage of bacteria. 



liquifying to the walls of the tube at the top and 

 then proceeding downwards horizontally, 

 same as saccharose, 

 lasting a few days, 

 semi-transparent, 

 ends abrupt, square. 



cloudy with flocculent particles; i. e. cloudy plus 

 flocculence. 



having a button-like, raised center, 

 border wavy, with shallow sinuses, 

 having hair-like extensions. 



growth follows the needle when touched and with- 

 drawn; sediment on shaking rises as a coherent 

 swirl.
