Document Summary
Microbiologists: study protozoa, bacteria, fungi, viruses, algae, and diatoms. Microbes: too small to be seen with naked eye, can be cellular and noncellular: when microbes are in very large numbers, you can see them with the naked eye (mold on bread) Microbial communities: lakes, human mouth, sewage plant, etc: all habitats are different and each microbe is habitat specific (algae needs light) Agriculture: this includes things such as cows and plants, plants have bacteria to help them perform natural processes (soybeans), such as getting rid of nitrogen. Food: biofuel, cellulose + corn starch--- glucose --- fermentation --- ethanol, canned goods, alcohol (beer), cheeses, etc, saccharomyces cerevisiae: yeast used to make beer, canned goods have added preservatives in order to keep. Use to cause a lot of disease: microbes cause 25% of death worldwide, examples: hiv, respiratory infections, diarrheal disease, tb, Eukaryotic cells are a lot more complex.
