Fig. 1 in Antifreeze Water-Rich Dormant Cysts of the Terrestrial Ciliate Colpoda cucullus Nag-1 at -65 ℃: Possible Involvement of Ultra-Antifreeze Polysaccharides
Fig. 1. Tolerance and antifreeze activity of wet resting cysts of C. cucullus Nag-1 in response to cooling (−65℃) and their osmolality. (A-1) Tolerance of encysting cells at various encystment stages. The abscissa indicates the cyst age of encysting cells. The ordinate indicates the excystment rates (%) of resting cysts (aged 1 day or more) or viability (%) of vegetative cells. Closed and open circles show the excystment rate or viability of the cells cooled at −65℃ for 24 h or more and those without cooling, respectively. The viability (%) of frozen vegetative cells is expressed as a percentage of the total number of tested cells (> 50 cells). The rate of excystment was expressed as a percentage of the total number of observed cells (50 cells). Points and attached bars correspond to the means of 6 measurements and the standard errors (SE), respectively. In each set of experiments (i.e., the cooling group and control group experiments), the same lot samples were used. (A-1, inset photograph) 1-week-old cysts cooled at −65℃ for 24 h, and thawed at room temperature. 'a': a living cyst, 'b': a cyst whose cell body shrank and detached from the cyst wall (killed cysts). (A-2) Inhibition of ice crystal growth in cell fluid obtained from C. cucullus Nag-1 resting cysts (2 or more weeks old). Upper and lower photomicrographs are pure water and cell fluid obtained from Colpoda cysts cooled at −65℃ for 30 min. (B-1) Changes in cell size of 2-week-old cysts after transfer from encystment-inducing medium without sucrose to medium containing 1 M sucrose. One run of measurement was done in the same cells. Points and attached bars correspond to the mean diameter obtained from 5 cells and the SE, respectively. (B-1, inset photograph) A 1-week-old resting cyst kept in encystment-inducing medium (left), and the same cyst transferred and kept for 5 min in the encystment-inducing medium containing 1 M sucrose (right). (B-2) Cell size of 2-week-old resting cysts immersed for 10 min in encystment-inducing medium containing various concentrations of sucrose. One run of measurement (0, 0.05, 0.1, 0.3, 1 M sucrose) was done in the same cell. Points and attached bars correspond to the mean diameter obtained from 10 cells and the SE, respectively.

Fig. 3. PAS-stained SDS-PAGE gel (left) analyzing total proteins in encystment-induced cells, and CBB-staining of PAS-stained gel (right).
Fig. 2 in Antifreeze Water-Rich Dormant Cysts of the Terrestrial Ciliate Colpoda cucullus Nag-1 at -65 ℃: Possible Involvement of Ultra-Antifreeze Polysaccharides
Fig. 2. Detection of polysaccharides in C. cucullus Nag-1 encysting cells. (A) A PAS-stained vegetative cell (a), a 3-h-old immature cyst (b), a 1-day-old immature cyst (c), an almost mature cyst (5 days old) (d) and a toluidine-blue stained thick section of a 1-week-old mature cyst (f). (e) PAS-stained 1-week-old mature cysts at 10 min after onset of excystment induction. cw: cyst wall, ec/en: an ectocyst layer lined with endocyst layers, ma: macronucleus, m: plasma membrane, elb: electron-lucent body (probably stored carbohydrate granules). (B) Tol- erance of excystment-induced cells (1-week-old cysts) to a temperature of −65℃. Excystment was induced for 10 min, and then the cells were cooled at −65℃ for 24 h and then thawed at room temperature. The excystment rate (%) was measured at 24 h after thawing, and was expressed as a percentage of the randomly chosen total number of cells (50 cells). Columns and attached bars correspond to the means of 6 measurements and the standard errors (SE), respectively. In each set of experiment (i.e., the cooling group and control group experiments), the same lot of samples was used. There was significant difference between the columns (p <0.01, Mann-Whitney test).
