Document Summary

Biodegradation: process in which highly complex substances are broken down into simpler products by the action of microbes. Mineralization: the breakdown of organic compounds into inorganic forms by microbes. Xenobiotics: man-made synthetic organic compounds which are partially or completely non-degradable and create pollution problems. Bioremediation: removal or detoxification of man-made xenobiotics compound by the use of microorganisms. Biodeterioration: process of chemical or physical alteration or deterioration of natural or man-made products of economic importance by microorganisms in such a form that decreases the usefulness of that product. Bioaugmentation: when microbes are added in combination with fertilizers containing nitrogen and phosphorus which enhance their growth to biodegradable pollutants. Biofilms: when microbes live in communities forming layers of organic matter. Bioaccumulation: accumulation of contaminants by species in concentration that are in order of magnitude higher than surrounding environments. This process is the sum of: bioconcentration, biomagnification.

Can anyone please answer the following questions from"Prescott's microbiology 8th Ed. Chapter 26? I have an examtomorrow and I lost my book today and only have these lists ofquestions...so please..

You don't have to answer all of them so if you have an answer toany of these, please help! (Answers should be from thetextbook...)

1. What is biogeochemical cycling?

2. Describe the consortia of microorganisms that oxidize methaneanaerobically. Why are two physiologically distinct microbesrequired for this reaction?

3. Define mineralization and immobilization, and giveexamples.

4. What is unique about lignin and its degradation?

5. WHat C,N, and S forms will accumulate after anaerobicdegradation of organic matter? Compare these with the forms thataccumulate after aerobic degradation.

Degradation of many man- made andnaturally occurring organic compounds take place under methanogenicconditions. Benzoate is the first aromatic compound to be examinedin methanogenic enrichments; however, no pure methanogen has beenisolated. What is the application of methanogens to thebioremediation of various organic Compounds? Why is it difficult toculture and isolate methanogenic bacteria? Identify the role ofboth carbon and energy sources in the methanogenic process. Whatare the limiting factors that dictate the success or failure ofmethanogenic bacteria to biodegrade and what type of compounds canbe biodegraded?

which of the following is false concerning biofilms?

a. they are polymer encased communities of microorganisms growing together

b. they are more susceptible to host defenses and antimicrobials because the microbes are together rather than spread out

c. dental plaque is an example of a complex biofilm

d. biofilms would also be important in industry where their accumulation in pipes, drains, etc could interfere with processes and damage equipment

e. all of the above are true
