Name 5 organisms that can carry out nitrification, write the chemical reaction, what enzyme carries out the process? Briefly explain how it works.

I need to find two gram positive and two gram negative pathogenic bacteria that may be classified as being facultative anaerobes. What tissues or organs do these bacteria target in the human body? Why is it to their advantage to be able to use either aerobic respiration or anaerobic respiration/fermentation?

Which of the following is an example of a chemoorganoheterotroph? A.) An organism that gets its energy for ATP from the sun and its C from other organisms B.) An organism that gets its energy for ATP from organic molecules and its C from other organisms C.) An organism that gets its energy for ATP from the sun and synthesizes C-C bonds from simple molecules D.)An organism that gets its energy for ATP from inorganic molecules and synthesizes C-C bonds from simple molecules

Using the data in the picture below, answer the five questions in the pictures.

Bacterium F had the lab results below. What can you tell me about the carbon food sources it ferments and the kind of end products it produces in anaerobic respiration? View attached photo.

Which of the following groups of bacteria require or will use oxygen for respiration i. obligate aerobes ii. facultative anaerobes iii. obligate anaerobes iv. microaerophile v. aerotolerant anaerobe i & iv ii. & iv Oi&ii i, ii, iv ii & iv

Where are the endospores located in this picture, and what color are they? 20 00 ASM MicrobeLibrary.org Ⓒ Keplinger

Describe the process of binary fission. Which methods in the lab can be used to measure growth? Which phase of growth should be used to set up lab cultures for assays?

Bacteria that are obligate intracellular pathogens of humans are considered to be Autotrophs Heterotrophs Photosynthetic Hyperthermophiles Chemolithotrophs Which of the following statements best describes the pathogenesis of Clostridium botulinum? It elaborates an exotoxin that is a lecithinase that causes tissue necrosis. It elaborates a toxin that suppresses the release of inhibitory neurotransmitters. It produces a polysaccharide capsule that inhibits phagocytosis and contributes to invasion of the central nervous system. It elaborates a toxin that inhibits the release of acetylcholine at cholinergic synapses. It produces a leukotoxin that leads to abscess formation.

Out of the 5 possible oxygen requirements (Obligate aerobes, microaerophiles- is E. coli, Pseudomonas aeruginosa, and Clostridium sporogenes? sketch below (or describe well with words), what growth would look like for each species in FTM tubes.
