Archaebacteria Habitats: Anarobic enviroments - without oxygen Thermophiles - heat lovers Methanogens - produce methane gas Halophiles - salt lovers
 * unicellular
 * live in extreme habitats
 * one of the first organisms to inhabit Earth
 * hot springs
 * salty lakes
 * swamps

Eubacteria:
 * Common bacteria
 * Most use oxygen. Few cannot live in oxygen
 * Decomposers
 * Used in food making
 * Cause diseases
 * Biomediation - bacteria that clean up oil spills

Shapes of Bacteria
 * Cocci - round
 * Bacilli - rod
 * Spirilla - spiral

Planes - staph Chains - strepto (ex. strept throat)

Classifying Bacteria
 * Gram staining
 * Stains bacteria
 * Some bacteria stain pink. Others stain purple
 * Gram stain positive - purple
 * Gram stain negative - pink
 * This tells scientists what kind of wall bacteria has more peptidoglycan more rigid wall - gram positive
 * Agar - media that is used to grow bacteria
 * Strict aerobic - grow only in presence of oxygen
 * Strict anaerobic - grow with no oxygen
 * Facultative anaerobic - prefer oxygen enviroments but can grow throughout a medium
 * Some can metabolism certain substances
 * Lactose - bacteria can metabolize lactose (ex. lactobacillus)

Motille - some bacteria can move throughout a media.
 * Differential media - some shows different reactions
 * Selective media - some can grow certain bacteria

Viewing microbes
 * Resolution (seeing detail) can be increased using immersion oil
 * Allows light ray to go directly through objective lens

Reproduction - Binary Fission

Conjugation - Bacteria gives its DNA to another bacteria
