Most bacteria lack or have very few internal membranes, which means that they don’t have some kinds of organelles (like mitochondria or chloroplasts).

Because Gram - bacteria have less peptidoglycan, antibiotics like penicillin are less effective against them.

... torage does not stop all bacterial growth since spoilage does eventually occur. But the colder you store the product the longer it will take for the spoilage bacteria to grow and spoil the food.

Keep the food at 40 or less and you will get the shelf life you need with a properly processed food. | Examples of Control of Bacteria | There are other ways that one can control the growth of bacteria. Bacteria need water to grow and even though some of them have the ability to resist long drying out periods, keeping things dry will stop growth and in some instances will kill them. Therefore, it is a good policy to keep utensils and some equipment dry when not in use. Remember, too, that the bacteria responsible for spoilage of foods (mesophilic and psychrophiles) can be killed by hot water. Ten minutes at 150 degrees F. will be sufficient.

... bacterial cell walls | Bacteria may be conveniently divided into two further groups, depending upon their ability to retain a crystal violet-iodine dye complex when cells are treated with acetone or alcohol. This reaction is referred to as the Gram reaction : named after Christian Gram, who developed the staining protocol in 1884. It may seem a very arbitrary basis on which to build one's classification system. This reaction, however, reveals fundamental differences in the structure of bacteria. Electron microscopy shows that Gram-negative and Gram-positive bacteria have fundamentally different structures, related to the composition of the cell wall, amongst other things. | Cells with many layers of peptidoglycan can retain a crystal violet-iodine complex when treated with acetone. These are called Gram-positive bacteria and appear blue-black or purple when stained using Gram's method. Gram-negative bacteria have only one or two layers of peptidoglycan and cannot retain the crystal vio ...

Pili can attach two bacterial cells together: sex pili are necessary for the transfer of certain plasmids between bacteria. | Bacterial cells may carry a single flagellum, and are thus described as monotrichous . If the single flagellum is at one end of a rod-shaped cell it is known as a polar flagellum . If the bacterium carries a single tuft of flagella, it is said to be lophotrichous ( lophos - Greek for a crest). When the tuft appears at both ends of the cell, the bacterium is amphitrichous ( amphi - Greek for 'at each end').
