Cards

Term
Bioremediation
Definition
The use of living organisms, usually bacteria or archaea, to degrade environmental pollutants.
Term
Biofilms
Definition
A hard, polysaccharide-rich layer secreted by bacterial cells, which allows them to attach to a surface.
Term
Fecal Bacteriotherapy
Definition
Transplanting fecal bacteria from a healthy patient to treat a sick one. (Definition taken from wiki, not book)
Term
Firmicutes
Definition
Bacteria that are sometimes called "Low-GC Gram Positive" because their cell walls react positively to a gram stain and because they have a low precentage of quanine and cytosine in their DNA. They are rod shaped or spherical. The spherical ones might for chains or group into four. These are extremely common in the human gut. They can cause anthrax, strep throat, botulism, boils, gangrene, and more. (Pg. 513)
Term
Spirochaetes
Definition
Bacteria are corkscrew shaped. They move by beating their flagella, causing the cell to lash back and forth. (Pg. 513)
Term
Actinobacteria
Definition
Bacteria sometimes called "High-GC gram positives" because their cell-wall material looks purple when it is gram stained. Also because their DNA contains a relatively high percentage of guanine and cytosine. (Pg. 514)
Term
Chlamydiae
Definition
Chlamydiae may be the smallest of all major bacterial lineages. Only 13 species are known. They are spherical and tiny, even compared to other bacteria. (Pg. 514)
Term
Cyanobacteria
Definition
Formerly known as the "Blue-Green Algae". Only about 80 species of Cyanobacteria have been described so far, but they are one of the most abundant organisms on Earth. (Pg. 515)
Term
Proteobacteria
Definition
They form five major subgroups. Since they are so diverse, they are named after the Greek god Proteus, who could change into many different shapes. (Pg. 515)
Term
Probiotics
Definition
Introducing a microorganism to the body for its beneficial qualities. (Definition taken from Web, not book)
Term
Germ Theory
Definition
The theory that infectious diseases are caused by bacteria, viruses, and other microorganisms.
