- A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules. Describe a result of this organism’s metabolic pathways that could be beneficial to another organism (of any type) living in close proximityWhy might clinical medicine have an interest in understanding bacterial cell division at the molecular level? Explain why a hyperthermophile would probably not be a human pathogen. Describe four factors that may have an influence on the effectiveness of an antimicrobial treatment. Explain why 70% or 80% alcohol is more effective than 100% alcohol in controlling microorganisms.clostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.
