What is peptidoglycan?
Answer
An antibiotic that interferes with the
crosslinking of the bacterial cell wall
Question
What is penicillin?
Answer
A gelatinous substance that provides cells
with additional protection from host
immune responses

Question
What are auxotrophs?
Answer
A term used to describe materials that are
inert to decomposition by microorganisms
Question
What is non-biodegradable?
Answer
The process that takes nitrogen gas (N2) and
assimilates it into organic material
Question
• What is nitrogen fixation?
Answer
These are organisms that will use oxygen
but can use fermentation in its absence

Answer
A soluble protein excreted by a
microorganism that can cause damage
to the host by destroying cells or
disrupting normal cellular metabolism
