Spring Semester 2012-13 University of Puerto Rico - Cayey RISE Program Template for Laboratory Summaries of Assignment 3 Biol. 4997-Biomedical Techniques Due date May 3, 2013 Reg.# 7 Name Juan E Maldonado Weng Date: 3 de mayo de 2013 Summary 7. Phages & Proteomics February 8 & April 12 In this laboratory workshop, much has been learned about bacteriophages. These impressive organisms, or non-living things (still in debate), are viruses that affect bacteria. There are widely diverse and, like fingerprints, every phage is unique. Much is not known on how they can be applied usefully for humans but they are very interesting for their behavior and diversity. For reproduction, each phage invades a bacteria and duplicates within it. In the workshop, a soil sample was tested to see if there were any phages. In a plate of broth, bacteria were added to feed phages so they could have been revealed as little hollow dots on the plate. This technique was done various times until recently. This discovery of a phage has led to the purification process which is to pick out a single phage from the cluster. Even though the purification process is not yet completed due to the recentness of the discovery, the goal is to reveal the protein strands of the phage. This workshop was difficult yet very rewarding. Word Count___172__ Summary 8. Water sampling, testing, and statistical application March 8 & April 26, 2013 In this fascinating workshop, water that you drink might have small communities. The goal was to understand how to test the quality of water. Many sources of water may be found contaminated by coliforms which are microorganisms. It is very important to understand that even though the water might have these microorganisms, it is still safe. It might be even safer than processed water because the amount of chemicals used can be harmful. Water samples were brought and tested. Because of these tests, a result might bring the fact that this researcher’s high school’s water supply, which is open for people who live in rural areas, is quite clear from contamination. The results, which were verified with a repeated testing, could be doubtful

Even though the results are uncertain, the workshop by Prof. Arce was very helpful because of the understanding of contamination and water-quality testing which will always benefit the community. Water is the source of life and it continues to support it. Word Count___178____
