18.1 Bacteria Objectives: 8(C) Compare characteristics of taxonomic groups, including archaea, bacteria, protists, fungi, plants, and animals. 11(C) Summarize.

An introduction to bacteria They Are Everywhere. Prokaryotes Prokaryote: Single-celled organism that lacks a true nucleus (also called bacteria) Prokaryote:

Living Things 1.7 million species been classified suggested around 8.8 million species all are put into groups based on genetics 3 main domains (groups)

Domain Bacteria and Domain Archaea Bacteria: Archaea BASIC CHARACTERISTIC of Both: Unicellular Heterotrophic or Autotrophic Prokaryotic.

Generally… Different classifications Very small

Prokaryotes Chapter 27. Found wherever there is life; thrive in habitats that are too cold, too hot, too salty, etc. Most live in symbiotic relationships.

Bacteria Quick Fact – Used to be in the Kingdom Monera – 1 kingdom, now they are in 2 separate kingdoms and 2 separate domains. Remember: New discoveries.

3 DOMAINS – Tree of Life

More on Classification Why the change from 5 kingdom to 6 kingdom?

Prokaryotes: Eukaryotes: What came first: Prokaryote or eukaryote?

Prokaryotes vs. Eukaryotes

Archaea VS Bacteria Single celled Prokaryotes Ribosomes, Cell Wall, (Flagella – optional) Common Ancestor Size/Shape Mesophiles Cell wall composed of protein Cell wall composed of peptidoglycan (sugar- protein complex) DNA, RNA, protein synthesis machinery DNA, RNA, protein synthesis machinery Extremophiles Reproduction Mesophiles Do not respond to antibiotics Where they are found Single celled Prokaryotes Ribosomes, Cell Wall, (Flagella – optional) Common Ancestor Size/Shape Mesophiles Cell wall composed of protein Cell wall composed of peptidoglycan (sugar- protein complex) DNA, RNA, protein synthesis machinery DNA, RNA, protein synthesis machinery Extremophiles Reproduction Mesophiles Do not respond to antibiotics

BACTERIA

Methods of Classification Shape Gram Staining Habitat Nutrition

DIFFERENT SHAPES Coccus (pl. cocci) Bacillus (pl. bacilli) Spirochetes (pl. spirilli)

-Gram stain applied to bacteria to determine cell wall composition Gram Staining

Gram-negative bacteria Gram Staining Results Gram-positive bacteria

HabitatMETHANOGENS -Produce methane gas -Found in guts of some animals HALOPHILES - Salt loving THERMOPHILES -Heat lovers MESOPHILES - Live in moderate temperatures of 15-40ºC

Nutrition Autotrophs -Heterotrophs –

Defense!!!! =related =related White blood cell eating bacteria Naturally our immune system fights them Give Antibiotics

Reproduction in Bacteria Why study reproduction in bacteria? What is the advantage of asexual vs. sexual reproduction?

Conjugation

Transformation

Transduction

Endospore Formation Question: Why is the formation of an endospore beneficial to the bacteria?

BENEFICIAL USES OF BACTERIA Nitrogen fixation Recombinant DNA technology Genetic studies

Other Applications of Bacteria Waste Management – bioremediation uses bacteria to remove toxic material (oil, acid, pesticides, radioactive wastes) Sewage Treatment – bacteria decompose organic matter (i.e. septic tanks with human feces) Dairy Foods – used to create dairy products (texture, flavour). – Probiotic bacteria in yogurt!
