On 0 day (Initial viable count) |
After 3 days | After 7 days | ||
1. | E. coil (ATCC -10148) | 8.2 X 103 | 7.1 X 103 | 5.0 X 103 |
2. | S. typhi (NCTC - 786) | 7.5 X 103 | 6.2 X 103 | 4.0 X 104 |
3. |
Ps. Aeruginosa (Fisner's immunotype IV) |
5.0 X 102 | 2.0 X 102 | 7.0 X 101 |
The result therefore indicated that the above mentioned stainless steel tank does neither promote the growth of the organisms nor does it exhibits any bactericidal activity. |
