BacterialGrowthin LiquidMedia
LEARNING OBJECTIVES
Overall: Examine growth of bacteria in liquid broth both qualitative and quantitatively
Detailed:
1. Understand how turbidity measurements can be correlated to growth of bacteria.
2. Draw a bacterial growth curve and describe what is happening in the cells in each phase.
3. Calculate generation time
4. Predict the effect of different growth conditions on a growth curve
5. Predict expected results of an experiment that studies bacterial growth.
6. Analyze the results of a simple experiment that studies bacterial growth.
BACKGROUND
Bacteria multiply by the process of binary fission. Binary Fission is a type of cell division
wherein number of cells are doubled after each division (1-> 2-> 4->8->16->32…..). The time it
takes for a population to double in number is called the generation time. This time varies
among different species and is influenced by the conditions in which the cells are grown, such
as temperature, oxygen, and acidity.
Each species of bacterium has an optimum for its growth conditions. Growth depends upon
several environmental factors surrounding the bacteria such as pH, temperature, oxygen
content and presence of nutrients in the medium. When the supply of nutrients is limiting,
bacteria will deplete the nutrients in their environment and produce waste products which will
eventually inhibit their growth
Bacterial growth can be followed by determining the number of bacteria in a sample over a
period of time. An increase in the number of bacteria over time indicates growth. Two
common methods used to determine growth are (i) standard plate count, and (ii) measurement
of absorbance. In the standard plate count method, a dilute bacterial sample is spread on an
agar plate and the number of colonies that are formed are counted after 24-48 hours of
incubation. This method assumes that a single bacterium will divide to produce a colony on the
plate. Therefore, the number of colonies multiplied by the dilution factor (in cases where the
sample is diluted before plating) will give the number of bacteria in the sample. The counts
determined by the standard plate count is reported as colony forming units (CFU). This method
counts only viable cells (live cells capable of forming colonies).
The second method follows the growth of bacterial cells by measuring turbidity or cloudiness
of the liquid culture. Turbidity of a culture increases as cells divide and increase in numbers.
Turbidity is measured using a spectrophotometer. FIG 1 shows culture tubes containing
increasing bacterial concentration (number of bacterial per mL of broth). As number of cells
increase (from tube left to right), the culture becomes more turbid. This is an indirect

a) This week we will discuss how deficiencies and imbalance in fatty acids and triacylglycerol metabolism can result in serious pathological consequences in humans. Select an example, explain the “normal” biochemical process and changes that occur due to abnormal processing. Where applicable, suggest how to avoid complications and possible treatments. Include figures to explain the biochemical pathway. Your post should be in three paragraphs, which can go to a maximum of four not more than that.
In the first paragraph introduce your topic, second and third paragraph you can write the normal biochemical pathway comparing with the altered pathway.
(b)In addition, we can cover those metabolic disorders that involve malfunction of urea synthesis.
c) These are very common misconceptions: Explain why these are not true.
• All fats are bad for your health.
• Using margarine instead of butter reduces cholesterol.
• Steroids are drugs that only deceptive athletes and bodybuilders use.
You do not have to write an essay on each discussion topic proposed above. Instead, you can choose only one discussion topic (either from the discussion board above or come up with your own relevant topic) and provide an elaborate and in depth descriiption and explanation.

In your opinion, what have we learned about ecological succession and disturbance that can be used to manage forests and other natural areas in a sustainable manner? Are there ways to mimic nature? Feel free to do additional research on this topic. For inspiration, please view the following video from the Vermont Land Trust. (transcript from video below as well as the link)
Hi, I’m Ethan Tapper, the Chittenden County Forester and we’re out here at the Andrews Community Forest in Richmond.
00:00:05
Andrews Community Forest is a 428 acre town owned property, acquired by the town in 2018 and conserved by the Vermont Land Trust, with the help from the Vermont Housing Conservation Board.
00:00:20
And so what we’re doing out here right now is demonstrating forest management done well, and trying to do it in this really open and transparent and inclusive way.
00:00:29
So the work that we’re doing is unusual in a couple of different ways.
00:00:33
One way is that we’re doing what’s called ecological forest management.
00:00:36
So we’re trying to manage our forests to be more like old growth forests, and to manage them based on forests natural disturbance dynamics.
00:00:45
The way that they change and grow and develop over time.
00:00:48
The other thing that’s unusual about it, is that we’re trying to do this in a way that is really open, transparent and inclusive, that brings people in and shows them why this is something that we don’t need to be afraid of, this is something we can be really proud of.
00:01:01
And so I’m standing here in what we call a group.
00:01:04
It’s a small opening in the forest that we’ve created, that’s supposed to simulate a small disturbance events.
00:01:11
So a little wind microburst, what happens when a bunch of trees fall over in a small area.
00:01:18
And as you can see, it looks really messy, just like it would look if a windstorm had come through here and blown all these trees over.
00:01:27
Now in ecological forest management messiness is not something that we wanna do away with, it’s actually something that we wanna encourage.
00:01:34
So instead of simplicity in uniformity, we wanna encourage irregularity and messiness and what I would call weirdness.
00:01:41
Leaving individual trees to grow as long as they wanna grow, leaving deadwood on the ground, creating pockets of trees of all different shapes and sizes.
00:01:52
This is a way that we increase the wildlife habitat benefits of the work that we’re doing, the resilience of our forests, the health of our forests, and help them be more like old growth forests.

You’ve been learning about marine conservation and recently watched the talk by Dr. Cinda Scott in Panama. Now you are asked to speak briefly at a meeting to convince stakeholders to support the establishment of a network of MPAs along the coast of small island country in the tropical western Pacific. Write a short script (in English) for what you plan to say in the 3 minutes you’re given to address the group. Be sure that you include arguments on the value of MPAs, and your advice on what you would encourage the MPA planning committee to consider when creating the MPAs.
Marine Protected Areas (MPAs) are a type of ecosystem-based management, which involves managing ecosystems in a holistic manner, taking into account all components of the ecosystem, including humans, and their interactions. MPAs aim to conserve biodiversity, restore habitats, and manage resources sustainably, aligning with the principles of ecosystem-based management.
Dr. Cinda Scott’s seminar talk was truly enlightening, highlighting the importance of interdisciplinary collaboration in marine conservation. Based in Bocas del Toro, Panama, her work exemplifies the integration of scientific research, community engagement, and education to protect marine ecosystems. I was particularly inspired by her emphasis on involving local communities in conservation efforts, ensuring that initiatives are sustainable and culturally respectful. Her approach to combining scientific data with traditional knowledge offers a powerful model for addressing environmental challenges in diverse regions.
