houses inside. The goal of the experiment is to prove using samples from cotton swabs inside and outside the tank and observing those 3 days in algar plates after how there is more colonies of bacteria inside than outside. Materials and Methods Materials we used to execute the experiment were a fish tank, 4 cottons swabs or q-tips, and 4 agar plates to contain the samples from the cotton swabs. The first step in the procedure was to find the naturally contaminated fish tank in our everyday environment

The Divinity of our Nation Topic Introduction: Explain why you chose this topic with the different example you witnessed after the bishop asked you to speak and the impression after reading 1776. Scripture: The Book of Mormon states, beginning in 1Nephi 2:20 that this is a choice land which we live in. I have found over 30 similar references throughout the Book of Mormon. 1. Explain that the Nephites and Jaredites were allowed to inherit this land under one condition: “he that doth possess

Comparison between MPN and E coli Petri film: The use of E.coli petrifilm seems more reliable than MPN since the value of MPN is less than E.coli petrifilm in the same group. It showed that MPN method was underestimated the total coliform and E.coli numbers. The Most Probable Number test methods described in this Practical provide guidelines for detection and enumeration of bacteria of food and water origin. Then we can prevent food borne infections and diseases occurring more commonly. Disadvantages

Isolation and Purification of Lyngbya majuscula on Nutrient-enriched Agar Plates A Special Problem ABSTRACT Lyngbya majuscula samples were obtained from the Phycology Laboratory stock culture of the UPV Institute of Aquaculture. Five (5) mm fragments of these were inoculated into agar plates that used 1% agar concentration enriched with varying concentrations (1.0%, 1.5%, and 2.0%) of Hughes, et. al. (1958) Mineral Medium No. II. After ten (10) days of culture, the Trichome Length

more germs than only dipping once. Through experimental procedures researchers inoculated a sample of salsa onto agar plates that were either doubled dipped from a jar of salsa or were only single dipped from the same jar of salsa. After 48 hours of incubation the plates were examined to see whether the double dipped plate contained more growth compared to the single dipped plate. Examing the growth of the two resulted with the double dipped salsa showed to have double the amount of growth than the

IDENTIFICATION OF UNKNOWN BACTERIA It is virtually impossible to identify bacteria based on physical characteristics alone. This is due to the fact that there are only a few basic shapes and physical features commonly seen in the prokaryotic world. Instead, biochemical testing has been used to make bacterial identification down to the “species” level. These schemes are based on creating and matching biochemical profiles of the production of enzymes, acids and gases by isolated pure cultures
