Chapter 6 Microbial Growth
Bacteria utilize trace elements for?
What are cofactors for enzymes?
This organism is mainly a concern for causing food spoilage
What are psychrotrophs?
The sum of all chemical reactions in an organism
What is metabolism?
This enzyme is secreted to break down large molecules
What are exoenzymes?
Washing your hands only lowers microbes in the area, therefore, it is considered what type of microbial control
What is degerming?
These organisms obtain their energy and carbon from metabolization of organic matter through dead organisms.
What are saprobes?
What is plasmolysis?
These differ from organism to organism and are responsible for establishing metabolic pathways
What are enzymes?
What are riboenzymes?
UV lighting can damage DNA and cause T-T diameters, this is considered what kind of biological term
What is bactericidal?
Streptococcus pyogenes can grow where only a small amount of oxygen is present
What is an Aerotolerant Anaerobe?
At this phase of growth, endospores are formed
What is the stationary phase?
This macromolecule is typically an enzyme
What are proteins?
Amylase is only produced when starch is present
What are induced (adaptive) enzymes?
These bacteria and fungi are responsible for the majority of antimicrobial drugs
What are bacillus and penicillium and ceohalasporium
Peroxidase neutralizes hydrogen peroxide in the absence of oxygen not being utilized
What is peroxidase used for?
Staphylococcus aureus is found where osmotic pressures are high, this categorizes the organism as which biologically correct term
What is osmotolerant?
This part of an enzyme is both the apoenzyme and cofactor combined
What is a holoenzyme?
Series of redox reactions using electron carriers?
What is oxidative phosphorylation?
This drug targets protein synthesis and is considered selectively toxic
What is tetracycline, streptomycin, or chloramphenicol
Neisseria gonorrhea and Brucella are both organisms that grow where carbon dioxide is higher than normal atmospheric levels
What are capnophiles?
This media is used to cultivate anaerobic bacteria
What is reducing media
Sulfanilamide inhibits the synthesis of folic acid by blocking PABA, which is the metabolic term for this drug
What is a competitive inhibitor?
Pyruvate is too *blank* as Acetaldehyde is too *blank*
What is lactic acid fermentation and alcohol fermentation?
A virus will act as a genetic vector passing DNA from donor to recipient for antibiotics-resistant
What is transduction?
