Bacterial cultures can be preserved for long by suspending in glycerol broth and storing at -20 to -70 degree Celsius. The protocol as below: To 0.85 ml of bacterial culture, add 0.15 ml of sterile glycerol (sterilized by autoclave, final glycerol concentration : 15%, v/v).
The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. Shape of Bacterial Cell.1  Cocci (or coccus for a single cell) are round cells, sometimes slightly flattened when they are adjacent to one another.he three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes.
