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).
Genetic information in bacteria is stored in the sequence of DNA in two forms, that is bacterial chromosome and plasmid. The following are the properties of a bacterial chromosome. 1  Location: Within nucleoid region, not surrounded by nuclear envelope. 2  Number: 1 chromosome each cell.ize of bacteria ranges between 0.2 Âµm and 700 Âµm in diameter, with the normal range of about 1-5Âµm in diameter. Bacteria are about 10 times smaller than eukaryotic cells, which leads to their unique features of growth.
