Document Summary

The yellow highlighted arrow is a process that is performed by: chemoheterotrophs respiring aerobically, chemoheterotrophs respiring anaerobically, oxygenic phototrophs, anoxygenic phototrophs, chemolithotrophs respiring aerobically, chemolithotrophs respiring anaerobically, chemoheterotrophs fermenting. The yellow highlighted arrow is a process that is performed by: chemoheterotrophs respiring aerobically, chemoheterotrophs respiring anaerobically, oxygenic phototrophs, anoxygenic phototrophs, chemolithotrophs respiring aerobically, chemolithotrophs respiring anaerobically, chemoheterotrophs fermenting, 1, 3, 2, 4, 6, 5, 6, 7. The following two questions refer to the stratified lake picture. Aerobic chemoheterotrophs are likely to be found in regions: The bacterial called methylotrophs oxidize methane for all energy using the reaction: Living in a cow rumen would seem like a great thing for these organisms to do, but they don"t. 78% of the atmosphere of the earth is n. the source of this is mostly from: bacteria metabolism, volcanoes, evaporation from the ocean, light activated decay of organic matter, fossil fuel burning.

You are working in a food safety lab and were given some samples to evaluate for microbial contamination. The particular sample youâre working with today is a potato purchased at local farmerâs market booth. This farm does not use organic growth techniques. You swabbed the potato and performed a T-streak on MacConkey agar. From this you isolated several different colony morphologies, but one was of particular interest. The colonies were round and very glossy. On MacConkey agar they develop a reddish color.

You amplified one of these colonies for further analysis.

1. You prepare a wet mount and observe the microorganism under high magnification. You find that it has a rod shape and is non-motile.

2. You inoculate a thiolglycolate tube with this organism and incubate it overnight. Results are shown below.

Growth in Thiolglycolate (it is cloudy all the way to the bottom)

3. You inoculate a BD Enterotube with your unknown isolate. The results are shown below.

1 2 3 5 6 7 8 9 11 12

Glucose Lysine Ornithine Adonitol Lactose Arabinose Sorbitol V/P Urea Citrate

Color Yellow Purple Yellow orange yellow yellow yellow red pink blue

Gas? Yes

Note: I left out chambers 4 and 10 since you have no experience reading them and interpreting the results. The organism is negative for Indole, H2S, Dulcitol, and PA.
