rely on other organisms to make the organic compounds, such as glucose, that they use as carbon sources

Organic carbon sources are disassembled to generate energy and reassembled to make cell constituents such as proteins and carbohydrates

use CO2 discarded by heterotrophs to make complex cell constituents made up of C, H and O

the organic compounds synthesized by autotrophs can later be used as carbon source for

those microorganisms growing in extreme environments.

Some organisms capable of growing at temps above boiling or below pH of 2

Bacteroides fragilis- normal intestinal flora is killed when exposed to air

Aerobes at top and anaerobes at bottom of tube

Enables us to determine anaerobe from aerobe

Creates oxygen gradient after autoclaving

System in which we remove all oxygen present

Placed into closed system with packet that releases H2 and CO2, which effectively removes oxygen

Can be constructed by a single species or by multiple

Have biofilms that enhance than attachment to host

mass of bacteria that stick to and multiply on a solid surface

Can be constructed by a single species or by multiple

More and more cells bind to a surface, they can communicate with each other by sending and receiving chemical signals

Increase antibiotic resistance by limiting antibiotic access to the center of the biofilm

Certain gram positive (Clostridium tetani (tetanus), Clostridium botulinum (botulism), Bacillus anthracis (anthrax)

Develop dormant spores that are heat and desiccation resistant

Normal vegetative growth- metabolically active

what changes Color of agar (either red or yellow)

only Staphylococcus species will grow

Pseudomonas aeruginosa, a gram negative organism

Selective: only gram negative organisms can grow

Differential: lactose fermenting or not? pink=lactose fermenting tan=not

Direct counting of living and dead cells

Petroff Hauser Chamber

Direct counting of living and dead cells

Microorganisms are ubiquitous and have different...

pH growth conditions (acidohplie, neutrophile, alkalophile)

Temperature growth conditions (psychrophile, mesophile, thermophile)

Abillities to survive under high pressure (piezophile or barophile)

photosynthesize and make its own nutrients
