0-52 |
Sentence |
denotes |
Bactericidal or bacteria removal efficiency of Resp. |
| T188 |
53-90 |
Sentence |
denotes |
A is shown in Figure 6 and Figure S7. |
| T189 |
91-247 |
Sentence |
denotes |
In the 2.5 cm × 2.5 cm designated area of each web, non-treated samples showed ~1.46 × 106 and ~2.53 × 106 CFUs on the coverweb and stiffener, respectively. |
| T190 |
248-451 |
Sentence |
denotes |
Microwaving, oven-dry, and UV treatment showed similar bactericidal effect up to about 82%; in fact, this is inconsistent with previous studies [18,20], where 99.99% inactivation efficiency was achieved. |
| T191 |
452-603 |
Sentence |
denotes |
This discrepancy can be attributed to the different treatment conditions, such as irradiation intensity, treatment time, and amount of bacteria loaded. |
| T192 |
604-829 |
Sentence |
denotes |
In a previous study, 1.0 × 106 CFU of bacteria was loaded on the respirator with a nebulizer; and the UV irradiation (wavelength; 254 nm, 5 min) and microwaving (400 W, 10 min) resulted in complete inactivation of cells [18]. |
| T193 |
830-1010 |
Sentence |
denotes |
The case of an oven-dry treatment (100 °C, 15 min) also achieved 99.99% inactivation efficiency, when 5.0 × 104 CFU of bacteria was dropped onto the surface of the respirator [20]. |
| T194 |
1011-1141 |
Sentence |
denotes |
Compared to previous studies, this study built a harsher experimental condition with a higher loading of bacteria (5.0 × 106 CFU). |
| T195 |
1142-1334 |
Sentence |
denotes |
As a result, the intensity of microwaving (750 W, 2 min), UV irradiation (wavelength; 253.7 nm, 2 h), and oven-dry (90 °C, 1 h) of this study were insufficient for complete sterilization [51]. |
| T196 |
1335-1529 |
Sentence |
denotes |
Chemical solvents (ClO−, EtOH, and IPA) and laundering treatments showed no color change with cell staining, indicating 100% bactericidal or bacteria removal efficiency (Figure 6 and Figure S7). |
