 water at 28°C, measured with an oxygen electrode with constant 

 stirring. A, Undiluted Synthane product water added to cell suspen- 

 sion (final concentration, 10%). B, 50% Synthane product water 

 added to cell suspension (final concentration, 5%). C, Sterile medium 

 added to cell suspension. D, Undiluted Synthane product water 

 added to sterile medium (final concentration, 10%). E, 50% Synthane 

 product water added to sterile medium (final concentration, 5%). 

 F, Sterile medium added to sterile medium. 



Cytology 



Elliott and Kennedy (1973) reviewed the fine structure of 

 Tetrahymena. A series of three unit membranes enclose each cell; the 

 innermost is the plasma membrane, and the outer two form the 

 pellicle (Fig. 3a). Located immediately underneath the plasma 

 membrane are numerous small mucocysts. The matrix of mature 

 mucocysts displays a crystalline lattice pattern (Fig, 3b). The circular 

 mitochondrial matrix varies with different fixation techniques; 

 EUiott and Kennedy (1973) stated "... with good preservation the 

 matrix is densely granular." 



The most prominent cytological alterations of Tetrahymena 

 exposed to gasifier condensate occurred in the mitochondria and the
