Textbook Question
Chapter 1, Problem 2CT
In 1911, the Polish scientist Casimir Funk proposed that a limited diet of polished white rice (rice without the husks) caused beriberi, a disease of the central nervous system. Even though history has proven him correct—beriberi is caused by a thiamine deficiency, which in his day resulted from unsophisticated milling techniques that removed the thiamine-rich husks—Funk was criticized by his contemporaries, who told him to find the microbe that caused beriberi. Explain how the prevailing scientific philosophy of the day shaped the point of view of Funk’s detractors.

A microbiologist identifies a bacterium that is capable of degrading cellulose, lignin, chitin, latex, aromatic chemicals, and keratin. It produces metabolic byproducts that give soil a musty smell as well as some that can be used as antibiotics. Which of the following genera is being described?

Streptomyces
In 1928, British bacteriologist Alexander Fleming made an accidental discovery. He noticed that a fungus had contaminated
one of the agar plates he had streaked with a bacterial species to be studied. The fungus prevented the bacteria from growing
in the immediate area surrounding the fungus. Upon further investigation, Fleming found that the fungus produced a
substance that was the agent responsible for killing the bacteria. He called this substance penicillin. Given this information,
which statement best explains why Fleming's discovery is relevant to the general public today?
O Fleming's attention to detail diverted his efforts to investigate bacteria and likely robbed humanity of important
discoveries that he would have otherwise made.
Fleming's sloppiness in the lab serves as a reminder to all researchers that sterile technique is critical to preventing
unwanted fungal growth on bacterial plates.
Fleming's discovery enabled the development of chemical substances as antibiotics to…
1) Which of the following apply(ies) to Bacillus cereus and Bacillus anthracis? Choose all that apply:
a) B. anthracis forms spores while B. cereus does not
b) B. cereus is more lethal when it causes an infection
c) B. anthracis has extra-chromosomal DNA that makes it more pathogenic
d) Despite their similar names, the two are actually not at all related
e) The 16S rRNA gene sequences of these bacteria are more than 99% identical, meaning that they are actually members of the same species

- Choose the false statement: (Regarding Pasteur’s famous experiment) The swan necked flasks were important because they allowed the broth to remain sterile, while still remaining open to the atmosphere. Pasteur’s work with the swan neck flasks was only of importance to the food industry; his work occurred long before anyone, including Pasteur, had any awareness that diseases could be caused by microscopic agents. The swan necked flasks were used to prove that life could only arise from pre-existing cells.arrow_forwardWhy is sporotrichosis sometimes called rose gardener’s disease?arrow_forwardThe speciation of the genus Fusobacterium can be accomplished by a) pigment production b) bile hydrolysis lipase c) bile susceptibilityarrow_forward
