Sporulation in Distilled Water
Spores are formed when vegetative cells of sporing aerobes are shaken with distilled water at 37 degrees . These spores are derived from the small number of cells which survive lysis. The sporulation process involves increase and concentration of solid material in the cell, and is achieved at the expense of the products of lysis of 80 to 90 per cent of the resuspended cells.
متن کاملInactivation of Vibrio parahaemolyticus in distilled water.
Vibrio parahaemolyticus cells are readily inactivated in distilled water. The time of exposure required to inactivate 90% of the cells was between 0.9 and 4.4 min.

متن کاملAmmonia-water cation and ammonia dimer cation.
We have investigated the structure, interaction energy, electronic properties, and IR spectra of the ammonia-water cation (NH(3)H(2)O)(+) using density functional theory (DFT) and high-level ab initio theory. The ammonia-water cation has three minimum-energy structures of (a) H(2)NH(+)...OH(2), (b) H(3)N(+)...OH(2), and (c) H(3)NH(+)...OH. The lowest-energy structure is (a), followed by (c) and...
متن کاملChlorine in distilled water as a source of laboratory error.
SYSTEMATIC INVESTIGATION of low and erratic results obtained in one laboratory on standard solutions of uric acid revealed the presence of considerable free residual chlorine in the supply of distilled water. A further study was made of the effect of free chlorine on the determination of uric acid and other substances susceptible to oxidation-reduction reactions. Collier and Stuart (1) previous...
