Fats and wax-like substances may also constitute a more or less considerable portion of the bacterial Fig. 12. Microscope and accessories for bacteriological work. In the germ of tuberculosis, the cells have been found to contain per cent of fat and wax in their dry sub- stance. The nitrogen-fixing organisms of the azoto- bacter group frequently store up very considerable quantities of fat in their cells. Some species are observed to do this more than others. The so-called sulfur bacteria, found in some sulfur springs and in the sea, deposit within their bodies little.
