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 کاملWater electrolysis: Divide and conquer.
news & views the eventual transition to homogenous 3ʹ,5ʹ-linked genetic material. T echnologies for generating electricity from renewable resources, such as sunlight and wind, are on a steady trajectory of falling cost. Within the next decade, solar electric power is expected to reach grid parity, the point at which its cost will be equivalent (on a per-watt basis) to that of power generated fr...
متن کاملElectrolysis of water on oxide surfaces
In this paper, density functional theory (DFT) calculations are performed to analyze the electrochemical water-splitting process producing molecular oxygen (O2) and hydrogen (H2). We investigate the trends in the electro-catalytic properties of (110) surfaces of three rutile-type oxides (RuO2, IrO2, and TiO2). The two first of these oxide anodes show lower O2-evolving over-potentials than metal...
