CRSS 4610 Exam 1 Questions With
Correct Answers
Soil |Microbiology
Study |of |microorganisms |that |live |in |the |soil, |metabolic |activity, |role |in |energy |flow, |and |
nutrient |cycling
Physiology
how |they |grow |and |metabolize
Taxonomy
What |they |look |like |and |how |they |relate |to |each |other
Resilience |and |adaptability
how |are |they |impacted |by |environmental |factors
Symbiosis
,What |is |their |relationship |with |other |organisms
Antonie |van |Leeuwenhoek |(1632-1723)
Made |the |first |microscope, |not
microbiologist |by |training
Robert |Hooke |(1635-1703)
Examination |of |microscopic |protozoa, |molds |and |spores
Louis |Pasteur |(1822-1895)
Disproved |the |theory |of |spontaneous |generation; |invented |Pasteurization
Robert |Koch |(1843-1910)
Germ |theory |of |disease; |pioneered |solid |culture |techniques: |worked |a |lot |with |Anthrax |
(Bacillus |anthracis)
Martinus |Beijerinck |(1851-1931)
,Cultured |nitrogen |fixing |bacteria
(Rhizobium |and |Azotobacter), |discovered |the |presence |of |virus |in |soils
Serge |Winogradsky |(1856-1953)
Did |pioneering |work |on |S, |N, |Fe |transformations; |investigated |microbial |growth |on |CO2 |and |
inorganic |ions |(chemoautotrophy).
Alexander |Fleming |(1874-1939)
Discovered |the |evidence |for |the |first |antibiotic |(penicillin, |produced |by |fungus)
Selman |Waksman |(1888-1973)
Discovered |the |antibiotic |streptomycin |for |TB, |produced |by |a |soil |actinomycete |(bacteria |with |
filamentous |growth) |isolated |by |group |at |Rutgers |University
Pasteurization
treating |a |substance |with |heat |to |kill |or |slow |the |growth |of |pathogens
Koch's |Postulates
a |sequence |of |experimental |steps |for |directly |relating |a |specific |microbe |to |a |specific |disease- |
Isolate, |Inoculate, |Symptom, |Isolate
, Soil
- |A |dynamic |natural |body |composed |of |mineral |and |organic |solids, |gases, |liquids |and |living |
organisms |that |could |serve |as |a |medium |for |plant |growth.
- |Mostly |have |a |negative |charge.
Two |broad |types |of |soil
organic |and |mineral
Organic |if |soil |has
> |20% |organic |carbon
Rhizobium
symbiotic |fixers
Azotobacter
free |living |fixers
Chemoautotrophy
fixing |carbon |dioxide |by |oxidizing |chemicals
