Brock's Microbiology Ch. 16 Key Concepts in Bacterial
Diversity and Classification Questions With Complete
Solutions
Ability to form endospores Correct Answers Evolved at least
once in an ancestor to Bacillales, Clostridiales, and
Lactobacillales.
Acid-fast staining Correct Answers A diagnostic tool used to
identify Mycobacterium spp.
Acidobacteria Correct Answers Some species are classified in
Bacteria while others are considered Archaea.
Actinobacteria Correct Answers A taxon that is gram-positive
and can be differentiated from Firmicutes by relative G+C
content in their genomes.
Actinomyces Correct Answers A genus of bacteria that is
related to others listed but is not least related to Mycobacterium.
Aerated environment Correct Answers An environment with
high levels of oxygen.
Aerobic catabolism of glucose Correct Answers Begins rather
than aerobic degradation due to the presence of O2.
Aerobic or facultative anaerobic acetogens Correct Answers
Organisms likely isolated from aerobic growth conditions with
acetate and a soil sample heated to 80°C for 10 minutes.
, Agrobacterium tumefaciens Correct Answers A bacterium that
cannot form root nodules in plants and cannot mate with
bacteria, making it a poor host organism for genetic
transformations among different domains of life.
Antibiotic-producing Streptomyces spp. Correct Answers A
type of organism that can dominate certain habitats.
Antibiotics disrupting cell wall biosynthesis Correct Answers
Ineffective at harming growth of mycoplasmas.
Bacteroides Correct Answers A genus within Bacteroidetes
that contains unusual sphingolipids in their cell membranes.
Bacteroidetes Correct Answers Members of this phylum are the
most abundant bacteria present in the large intestine of humans
and contain unusual glycerolipids in their cell membranes.
Best bacterial genus for fermenting cabbage Correct Answers
Lactobacillus.
Best species for wastewater treatment Correct Answers
Zoogloea ramigera
Betaproteobacteria Correct Answers A functionally diverse
group that primarily uses anaerobic metabolisms.
Biosynthesis of vitamin K by Correct Answers Escherichia
spp. inhabiting the intestinal tract
