Culture (kuV-chur) [colo, cultum, to till, cultivate]. A 

 name loosely and indiscriminately applied to the act, 

 the liquid or solid medium used, and the product of the 

 process, in culture-experiments upon microorganism-. 

 The culture-media are of various kinds; mineral liquid-, 

 (see Raulin's Liquid, Cohn's Liquid, etc.), bouillons 

 of various kinds, gelatinous fluids, gelose, potato, 

 serum, etc. These media are first sterilized, usually 

 by heat (see Oven, Sterilization), but possibly also by 

 chemicals, by filtration, by cold, by steam, etc. The 

 infectious matter is then taken upon a sterilized plati- 

 num needle-point, pipet, or other instrument, and 

 transferred to the culture-medium. When the latter is 

 of semi-solid consistency, as gelatin, the inoculation 

 by the needle is called Stab-culture, Stichcultur 

 (Ger.), or par piq&re (Fr.)., the needle briny thrust 

 into the substance. When smeared over the surface, 

 it is called smear-culture, Strichcultur (Ger.), or 

 en stries (Fr.). The macroscopic features of the sub- 

 sequent development give important means ot differ- 

 entiation. For example, when the inoculated matter 

 forms a mass in the medium, pointed below and rising 

 like a nail-head above, it is called en clou, nail-shaped. 

 Then the medium maybe liquefied or not, variously 

 colored, peculiarly changed, sediment deposited or not, 

 etc. Subsequent microscopic examination of the cul- 

 ture-product, inoculation-experiments upon animal-, 

 etc., complete the study. Culture-bulbs, culture-, 

 culture-fluids, culture-media, culture-ovens, culture- 

 tubes, etc., are among the equipments of the bacteri- 

 ologist. C.-oven. See Oven.
