Bacteria - What are they?

Bacteria are . . .

✔ Single-celled organisms found in all types of environments

✔ Can only be seen through a microscope – measured in micrometer (one millionth of a meter)

✔ Prokaryotes they do not contain a nucleus

✔ Grouped in families – having the same bacterial ancestors.

E.g. Enterobacteriaceae

✔ A family member is a genus – each genus having developed its own peculiar characteristics. E.g. Escherichia

✔  A genus has different species E.g Escherichia Coli (E. Coli)

✔ Different shapes, sizes and many other characteristics

Bacterial Purpose / Activities -

Bacteria can be harmless, beneficial or harmful (pathogenic) . . .

Harmless

Do not affect humans

Beneficial

Beneficial Bacteria - produce enzymes that:

✔ Aid food digestion and production of some vitamins - break down complex food molecules into simpler materials (especially in ruminants); Responsible for production of vitamin K and some b vitamins

✔ Are Involved in production of many foods eaten by humans – milk souring bacteria are used to produce yogurt, cottage cheese, and buttermilk; other bacteria used to produce vinegar and sauerkraut

✔ Are the principal agents of putrefaction - the anaerobic decomposition of organic materials, especially protein (i.e. contains nitrogen); produces foul odors

✔ Are the principal agents of decay - the gradual decomposition of organic matter exposed to air by bacteria and fungi.

Harmful (Pathogenic)

Pathogenic  bacteria cause disease by different mechanisms:

✔ Directly attack tissues (in other life-forms) – E.g.Bacterial Leaf Spot caused by Pseudomonas cichorii
