Kingdom Bacteria
True Bacteria
Single Celled
No Nucleus or Organelle
DNA- 1 Strand -turns on and
off
Microscopic
Parts of a Bacteria Cell
• Flagella- tail like
structure used for
movement.
• Chromosomes & DNAstores hereditary
information.
• Cell Wall- protection
Shapes of Bacteria
• Cocci- round
• Bacilli- oval shaped
• Spirilla- long and skinny
Combinations of Shapes
1. Strepto- Chains
2. Staph- Clusters
Bacteria Cell Reproduction
• Binary Fission- division
of bacteria by splitting
into 2 identical cells
from 1 parent cell.
• Asexual Reproduction
Helpful Bacteria
1. Food- develops acids to turn into different
tastes and smells.
- Ex. Cheese, Sauerkraut, Vinegar, Yogurt
*Pasteurization- Louis Pasteur, heating to high
temps and cooling slowing bacteria growth.
2. Aids Animal Digestion (Symbiosis)
– Bacteria gets food and shelter
– Helps animals break down plant sugars
Helpful Bacteria Continued
3. Enhances Plant Growth- takes nitrogen from
the air and brings it into the soil.
4. Industry
- Alcohol- Fermentation Process (acetone)
- Oil Eating- Used to clean oil spills.
5. Genetic Engineering
- Insulin
Harmful Bacteria
1. Disease Causing
Examples
-MRSA
-Meningitis
-Infections
- Tuberculosis
- Bubonic Plague
- Salmonella
- E. coli 
2. Causes Food Spoilage
Controlling Bacteria
1. Cold TemperaturesRefrigerator/ Freezer
Killing Bacteria
1. Disinfectant- chemicals
2. Fire
2. Salt- removes moisture
3. Sterilization- Boiling water
3. Petri Dish
4. Antibodies
Antibiotic Resistance
• Antibiotic- chemicals
used to kill
microorganisms.
• Examples
- Penicillin
- Streptomycin
- Augmentin
- Ampicillin
- Bacitracin
• Antibiotic Resistanceability of a bacteria to
tolerate antibiotics.
