Lysozyme is an enzyme that catalyzes the destruction of the cell walls of certain bacteria, occurring notably in tears and egg white. Lysozyme breaks down the bacterial cell walls and is used to extract recombinant proteins or DNA from bacterial cells. Also used as an antiseptic to prevent caries and treat infant formulas. Like mentioned before it is found in tears, saliva and mucous. It wasn't until 1922 that a Doctor named Alexander Fleming (1881-1995), observed the antibacterial action of Lysozyme when he treated bacterial cultures with nasal mucus from  patient suffering from a head cold.  

Serratia Marcescens is an opportunistic pathogen that cause nosocomial infections. It is resistant to many antibiotics traditionally used to treat bacterial infections, such as penicillin and ampicillin [9]. This is due to all of Serratia marcescens’ characteristics; unique membrane (LPS) as a Gram-negative bacteria, the ability to survive in aerobic and anaerobic conditions, and its motility Not only does S. marcescens have R-factors which encode genes for particular drug resistance, but it also contains sophisticated efflux pumps which further remove toxins that may be fatal to the microorganism.

This week in Lab the only plastic I am waiting to weigh is SPI6. The reason this one is taking longer is because when I rinsed it with DI water it soaked some of the water up which meant I had to leave it in longer to dry out than the other plastics. Then when it was completely done drying I put the hydrogen peroxide to get rid of any nature products that could have been left behind. Right now they are still drying, until they are completely dry is when I will then be weighing it and that will conclude my last sample for weighing. After that I will finally have all data to analyze. I will be determining which extraction method/ water solution works best on microplastics. I will also be determining plastic loss in all three different solutions and see if there was a was to better change the protocol that the NOAA developed for extraction of microplastics from sediments.

So the picture above shows the location of where I got the sample water though, though I regret not getting the coordinates of the exact location I took the water sample from because Tempe Town Lake is pretty big. This weekend while also this weekend I went to Tempe Town Lake again but the only difference was that there were a lot of dead fish just floating around and some even on shore. Which got me thinking if we might something new in the microplastic bacteria growth. There was also a report during 2014 where there was an extreme growth of E. Coli in Tempe Town Lake Water. “ Tempe has received water samples from Town Lake taken Thursday morning that show E. coli bacteria more than 10 times higher than the state's allowable” (Tempe Town Lake 'unsafe' water sample threatens race). I missed another great opportunity and forgot to take pictures of the dead fish. So perhaps maybe this week I will go again and take pictures.

“It's not what you achieve, it's what you overcome. That's what defines your career." —Carlton Fisk Growing up in a strict Hispanic Household my siblings and I were always told that we needed to become doctors when we grew up. That if we were doctors we would have a stable bright future. So of course in High School I would tell everyone that I would grow up to be a Doctor. I didn’t know what kind of doctor, I just knew I was going to be a doctor. Once I graduated High School and enrolled at Phoenix College, I told my advisor, “I want to be on the path that will make me a doctor”. So for 2 years I was taking all my pre-requisites to be a doctor. It wasn’t until my second year at Phoenix College and almost close to graduation that I wanted to be an ophthalmologist. So I looked online and started studying for my Optometry Entrance Exam (OAT). During that Summer 2019 of pure studying I also worked with Dr. Polidoro in her environmental/ Toxicology ...
