Bacteria of species A and species B are kept in a single environment, where they are fed two nutrients. Each day the environment is supplied with 19,860 units of the first nutrient and 31,950 units of the second nutrient. Each bacterium of species A requires 4 units of the first nutrient and 5 units of the second, and each bacterium of species B requires 1 unit of the first nutrient and 6 units of the second.
What populations of each species can coexist in the environment so that all the nutrients are consumed each day?

- Describe a circumstance (e.g. in its’ natural environment) where Staphylococcus species bacteria might benefit from being salt tolerant. - How might the ability to perform hemolysis benefit a hemolytic organism in its’ natural environment? - Imagine that you have a culture containing a single bacterial species. This culture may be one of several possible species. Describe a scenario where you use Mannitol Salt agar, Blood Agar, and EMB plates to identify the unknown bacterial species. That is, how would...
1. Single Species Growth Consider a single population where the per capita birth rate declines as the population size grows. Let N(t) be the population size at time t. Consider the following assumptions: (A1) The environment in which the species lives (including the climate, other species and the availability of resources like food, etc.) remains constant. (A2) The per capita birth rate is for some b>0. (A3) The per capita death rate is a constant d > 0. Note: This...
Lab Report-Carbohydrates 1. Purpose 2. Special Media for Isolating Bacteria (Lab #12) a. Why are dyes such as phenol red, eosin or methylene blue added to the media? b. How does the bacterium change the media (i.e color of agar or colonies) after incubation? C. In this experiment, which media are selective, and which are differential? d. How did the results observe on the mannitol salt agar and EMB agar correlate to the Gram reaction of the bacteria? e. What...
III. You isolate a new species of bacteria that only grows in the Antarctic. A wild type strain of this bacteria can synthesize its own alanine (alat) and its own tryptophan trp' ), both of which are essential amino acids. A mutant strain of the same bacterium cannot synthesize either of those two amino acids (ala trp'). You are interested in the degree of linkage between the ala and the trp genes in this new bacterial species. Fortunately, this species...
Puzzles, I need one or two word answer for each question. Thank you An acidic dye will give a ___________ stain. Dye in which the color portion resides in the positive ion. A bacterial cell wall containing only 2-3 layers of peptidoglycan and surrounded by an outer membrane composed of phospholipids, lipopolysaccharide, lipoprotein, and proteins. (2 words) During starch hydrolysis, starch is broken down to __________. Secreted by bacteria into the surrounding environment in order to break down larger nutrient...
Q1. Which type of organism in this lab can get its nitrogen from nitrogen fixation (converting N2 gas into ammonia), allowing it to grow even if easily used forms of nitrogen are not available in its water or food?CyanobacteriaDaphniaBosminaTroutQ2. A company is growing algae in big tanks to make fish food. However, the algae is not growing very quickly, and they suspect either phosphorus, nitrogen, or iron is limiting. What could the company do to figure out which nutrient is...
