I need an introduction for my senior biology research project. My project consist of the analysis of certain bacteria (organisms) present in water (sink water and water fountain from spout and from drain) and present in food such as deli ham (honey), deli cheese (mild cheedar), milk 2%, apple, carrot, bagged romaine lettuce, and plain bagel (individual). In all of these I have to analyze the presence of this bacteria or look if there’s any presence. The bacteria I’ll be analyzing are P. fluorescens, P. putida, and P. syringae. We will double check for P. aeruginosa. So in the introduction I need these research to be explain (what I’m doing or continuing since I’m just continuing a previous investigation), must have 10 minimum primary sources (ill attach them as comments after I post this), and most have in text (Literature) citations. I’ll attach what I have or the ideas but they aren’t organized and its not even close to be done. I need this done completely professional and appropriate since is for a senior research project.
