Bacteria sprinkling

The triclosan-(5-CD-IC was formed and small amounts were mixed with PCL powder, which was sprinkled onto cotton fabric and then covered with another piece of cotton fabric. The cotton-PCL/triclosan-( -CD-IC-cotton was ironed into a laminate, placed on an Agar plate, and then tested against the growth of E. coli bacteria. As can be seen from the test results in Table 5, E. coli bacteria were unable to grow upon the laminated cotton fabric containing triclosan-(i-CD-IC. In fact the laminated fabric was just as effective as films of PCL containing triclosan-P-CD-IC or pure triclosan. 

Bacteria That Degrade Pit Membranes. This form of attack is known mainly from softwoods submerged in water or from softwoods sprinkled with water. The bacteria direct their attack to the membranes of the pits in tracheids and ray parenchyma (Figure 9a). Pit membranes in the heartwood are much less affected than those in the sapwood. The thin walls of the ray cells in pine may also be degraded (98-99). The degradation of pit membranes results in a very pronounced increase in porosity, which is evident by a marked increase in the absorption of liquids. This phenomenon can be observed after only a few weeks of storage. 

The chemical process to make saltpeter is iderrtical to the one trsed inthe Middle Ages manure was mixed with straw and ash in compost piles and left alone for as long as a year with an occasional sprinkling of ttrine, which contains nitrogerr. Bacteria slowly turned organic nitrogen into nitrate, the salts of which crystallized on the surface of the compost piles very much like soda-salts do in dry flatlands At the end of the process, the saltpeter was collected and prrrified. 

Formaldehyde is employed as a disinfectant in both solution and gaseous forms for a wide variety of miscellaneous purposes. Common uses include disinfection of sickrooms by sprinkling with 2 per cent formaldehyde sterilization of surgical instruments by boiling 2 10 minutes w ith 2 to 4 per cent solution, destruction of anthrax bacteria in imported bristles b ...
