BIO 357-E General Microbial Ecology
Name of instructor:
Dr.Edwin H. Battley
When course is offered:
Fall semester, each year
An introduction to the study of the
interaction of microorganisms with their natural or artificial
environments. The course includes the historical development of
microbial ecology, a review of microbial diversity and structure,
ecological parameters, population interactions, applied microbial
ecology, experimental design and data analysis, and ecosystem
modeling as applied to microbial ecology.
Prerequisites: BIO 151, 152 or 171,172; CHE 322 or 332.
Office of instructor:
Life Sciences Lab 039A. Phone 516-632-8576, or
leave a message at the office of the Department of
Ecology and Evolution, 516-632-8600, asking that
it be put in the instructor's mail box.

Two midterm examinations and a final exam which
will be the equivalent of ywo hour examinations.
Based on the class average scaled to a 75% C.
Thus, after scaling:
- 93.33% - 100% = A 73.33% - 76.65% = C
- 90.00% - 93.32% = A- 70.00% - 73.32% = C-
- 86.66% - 89.88% = B+ 66.66% - 69.99% = D+
- 83.33% - 86.65% = B 63.33% - 66.65% = D
- 80.00% - 83.32% = B- below 63.33% = F
- 76.66% - 79.99% = C+
In arriving at a scaling factor, if the class average for a given
exam is less than 75.00%, the difference is taken between 75.00%
and class average, and this is added to each student's score. If
the class average for a given exam happens to be greater than
75.00%, the difference between the class average and 75.00% is NOT
subtracted from each student's score. Thus, it is possible for
every student to get an "A." It practice this has not happened.
The class averages for any given exam are usually below 75.00%.
The final grade is based on the same procedure, but using the
average of the averages.
Multiple choice exams machine scored.
Students with disabilities:
If you have a physical, psychiatric/
emotional, medical, or disabilities learning disability that may
impact on your ability to carry out assigned course work, you are
strongly urged to contact the staff in the Disabled Student
Services Office (DSS), Room 133 Humanities Bldg., 632-6748. The
DSS will review your concerns and determine, with you, what
accomodations are necessary and appropriate. All information and
documentation is confidential.
All exams must be taken. Makeup exams will be available
only to those who have a valid (in the instructor's opinion)
excuse for missing a regular exam. Except under most unusual
circum- stances makeup exams must be taken within one week of any
exam missed, at a time and place to be indicated by the
instructor. Because of the size of the class, this will be
strictly adhered to, and multiple makeups will not be given.
Therefore, make every effort to take an exam at the time it is
regularly scheduled, and take every precaution to avoid missing
The following topics will be discussed in
lecture. For a more detailed coverage, consult the text.
- 1. Microbial ecology: historical Development.
- 2. Microbial evolution.
- 3. Interactions among microbial populations.
- 4. Interactions between microorganisms and plants.
- 5. Microbial interactions with animals.
- 6. Microbial communities and exosystems.
- 7. Measurement of microbial numbers, biomass, and activities.
- 8. Effects of abiotic and environmental extremes on microorganisms.
- 9. Microorganisms in their natural habitats: air, water, and soil microbiology.
- 10. Biogeochemical cycling: carbon, hydrogen, and oxygen.
- 11. Biogeochemical cycling: nitrogen, phosphorous, iron, and other elements.
- 12. Ecological aspects of biodeterioration control: soil, waste. and water management.
- 13. Microbial interactions with xenobiotic and inorganic pollutants.
- 14. Biodegradability testing and monitoring the bioremediation of xenobiotic pollutants.
- 15. Microorganisms in mineral and energy recovery and fuel and biomass production.
- 16. Ecological control of pests and disease-causing populations.
- 17. Kinetics of microbial growth.
- 18. Thermodynamics of microbial growth.
Some of these topics will be dealt with more briefly than others.
In addition, several video tapes will be shown, and the lectures
will be accompanied by projection slides when this is instructive.
