The Waiting Game

After doing some research last Friday I came upon two different test solutions that would simulate gastric fluid and intestinal fluid. I took my research to Matt to make sure it was doable inside the lab and it turns out it is. Matt had to order a few thing to make it possible to make the fluids inside the lab which should be coming in sometime next week. So as of right now I am just waiting around for the items to come in but I have been using this time to type out my abstract, background information and procedures. It’s never too early to start thinking about the rough draft paper that will be due next month as we get closer to the end of the semester.

The digestion process - What happens to your food as it travels through ...

This week in lab I worked on getting the knots out of my project that keep me from getting it off the ground. After brainstorming for what seem like forever I came up with a plan that I’m happy with and most important I got the okay on. I’m going to be testing the effect of stress that probiotics go through inside the digestive system to see the survival rate. The two probiotics that I’ve chosen for this project will be Lactobacillus bulgaricus and Streptococcus thermopilus these two probiotics are mostly found in yogurt… Yep that’s right I’ll be using yogurt once again however this time around I’ll be only using three yogurt products instead of twenty products.

So the first thing I’ll be doing is testing each product to make sure they contain the probiotics I’m looking for. For test one I want to use LS differential agar but we don’t have in the lab. I guess I’ll have to talk with Matt to see if we can order it. This media would be able to differentiate between Lactobacillus bulgaricus and Streptococcus thermopilus. In the mean time I’ve been talking with Cory to see what else I could use that we already have inside the lab. After I get done with test one I’ll be moving on to the stress part of the project. Taking the probiotic and putting it into an environment that is like the human stomach. It looks like I’ll be use hydrochloric acid because it’s very close to the pH level of the stomach. I’m still thinking of what other material I’ll be using to create a similar environment of the stomach.

Breaking out the anatomy textbook

This week I have been researching how the digestive system works and mapping out the probiotic project. After talk to both Matt and Josh I got an understanding of where I want to go with this project and how I can accomplish it. The base of my project will be how different products with probiotics hold up in the digestive system. I will be measuring to see which product will have the most lactobacillus produced.

My first step was doing research on how food get digested in the stomach and moves on to the small intestine. While researching I also found out the pH levels of the stomach and small intestine. By getting this information I am trying to come up with a media that will be similar to the gastric acid in the stomach. There are other items that still need to be mapped out but I am happy to say that the probiotic project is coming together.

When it comes to the products I’ll be using I have narrowed it down to five products. I was going to use a pill supplement but after talking to Josh about it I decided to can that idea. There are just too many supplements out on the market. Instead I am going to stay with buttermilk and yogurts (three different types - homemade, Greek yogurt, plain yogurt). I will also be adding kefir into the mix. Kefir is a fermented milk drink made with kefir grains and has its origins in the north Caucasus Mountains. It is prepared by inoculating cow, goat, or sheep milk with kefir grains.

Continuing with probiotics project but I get to do the straw gardening as a side project too.

Hello everybody,

What a crazy start to this week with all the rain on Monday. I hope the rain didn’t cause too much trouble for anyone. As my title states I’ll be continuing my work with probiotics but this time around I’ll be taking products with probiotics (not just yogurt) and comparing them to one another on how they affect the digestive system. I am still working on getting this new project off the ground so I don’t have a lot to go on right now. I’ll be spending the next week doing research on the digestive system and see how I can bring this project into the lab.

As I stated last blog I really wanted to do a project with gardening. With the help of Paul I found a project that was totally cool to do. I ran it pass Josh and Matt and got the green light to go but ran into problems off the bat. Problems like where would we put the straw bale at??? Another problem that came up was the maintenance of getting the straw bale project started. Josh brought up the idea of doing the straw bale project on a mini scale so it would be easier to do inside the lab but I would really like to do the real thing. So as of right now Josh and Matt has said that I can do the straw bale project but we are still working out the problems we are facing.

A START TO A NEW SEMESTER / A START TO A NEW PROJECT......HOPEFULLY SOMETHING WITH GARDENING

Hello everyone, I hope everyone had a great summer. It’s a new start to a new semester and that means a new start with the S-STEM program. I am happy to be back and ready to start working. I am unsure of what project I’ll be doing, I still need to talk with Matt and Josh about it. However, I’m thinking I want to do something with gardening along the lines of growing something. Over the summer I got into gardening with my nine year old niece Clarice Marie. Our family garden was not the best success but we did have a lot of fun trying. The best part of it all was spending time with my niece and getting our hands dirty. Another reason why I want to do something with gardening is because gardening has been my go to thing to relax. By the end of last semester I was stress and it didn’t help that family issues arose at the same time school was finishing up. I needed to find something that would help release my stress and gardening was it. The way I look at it is why not have a project I can work on and at the same time relieve stress. I look forward to working in the lab once again this semester and seeing everyone. Image from http://www.exploratorium.edu/gardening/

Hi all, I don’t have too much to report this week. I only made it into the lab two days this week Monday and today (Thursday). I had a family emergency come up early Tuesday morning that kept me from coming into the lab on Tuesday and Wednesday. Besides working on the research rough draft I collected all my data from my notebook so far and made a excel spreadsheet. Below is just a glimpse of the finished spreadsheet. I couldn’t fit the whole spreadsheet into the print screen but the final spreadsheet has all twenty yogurt/dairy products on it and the tests done. The count of the tests done so far is eight however not all the tests were done to each product.

One thing after another……..feeling the pressure.

Last week was a very busy week for me. I had two test one in biology and the other in chemistry. So I did not post a blog or do the discussion bored. To top it off I had to start out this week with a test in math…..grrrrr! As the week went by one thing after another kept popping up adding more items that I need to take care of like the reapplication for the S-STEM program for fall 2014, the rough draft for the research paper, and let’s not forget the conferences at Metro Tech and Estrella Mountain. Speaking about the conferences I am starting to get a little worried because I am not getting the results I need to wrap up my research. I am either getting no growth or too much growth I cannot count. I hoping that I can get a count on all the yogurts by the end of next week fingers cross. I will be heading into the lab tomorrow to make a whole bunch of TSA plates so I can finish getting the results I need so I can move on to the next step.
