Who was the system of nomenclature established by and when? |
1735 by Carolus Linnaeus. |
|
|
What two names does scientific nomenclature assign an organism and which is capitalized? |
Genus is first and is capitalized, specific epithet (species name) is second and not capitalized. It is underlined or italicized. |
|
|
Escherichia coli |
Named for scientist Theodor Escherich. Coli means it lives in the colon or large intestine. |
|
|
What enzyme digests some of the cellulose in cotton to make soft faded jeans? |
Cellulases from Trichoderma fungus. Operate at safe temps and pH levels. Proteins that are readily degraded for removal from wastewater. |
|
|
What bacteria can produce both cotton and polyester, and how is it done? |
Gluconacetobacter xylinus. Make cellulose by attaching glucose to simple chains in the outer membrane of the cell wall. Cellulose microfibrils extrude through pores in the outer membrane then bundles twist into ribbons. |

|
|
What is a safer way to bleach fabric that can be removed from fabric and wastewater by enzymes? |
Peroxide produced by yeast that survived washing machine conditions. Researchers from Novo Nordisk Biotech cloned a mushroom peroxidase gene in yeast that survived the conditions. |

|
|
What soil bacterium was the gene that converts the bacterial by-product indole to indigo? What bacteria was that gene put into? |
The gene was taken from Pseudomonas putida and put into Escherichia coli. Turns it blue. |
|
|
What is it that over 25 bacteria make as a food reserve? What are they similar to? |
They make polyhydroxyalkanoate (PHA). They are similar to common plastics which are made from petroleum. |

Bacteria |
Unicellular, prokaryotes (not enclosed in a special nuclear membrane). May form pairs, chains, clusters, or other groupings. |
