INTRODUCTION Total Viable Count is a quantitative idea about the presence of microorganisms such as bacteria‚ yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method

explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

MICROBIOLOGY STUDY QUESTI0NS - EXAM 1 1. Briefly discuss the theory of spontaneous generation. What scientific evidence was presented to disprove the theory? Spontaneous generation- theory (until second half of 19th century) that some forms of life can arise spontaneously from nonliving matter‚ i.e. maggots from corpses Redi (1668)- demonstrated maggots do not arise from decaying meat by filling two jars with decaying meat (one sealed‚ one unsealed). Unsealed jar developed larvae and sealed did

past experience‚ and‚ therefore‚ by the establishment of a perceptual set. It is based on an experiment conducted by Bugelski and Alampay (1961). It was hypothesized that interpretation of an ambiguous stimuli that can be perceived as either a rat or a human face will be influenced by the context under which they view the figure and their past experience with other figures. That is they will be influenced by their perceptual set. The results from this study supported the hypothesis with the

Vandenberghe January 4‚ 2006 Chapter 2 Convex sets Exercises Exercises Definition of convexity 2.1 Let C ⊆ Rn be a convex set‚ with x1 ‚ . . . ‚ xk ∈ C‚ and let θ1 ‚ . . . ‚ θk ∈ R satisfy θi ≥ 0‚ θ1 + · · · + θk = 1. Show that θ1 x1 + · · · + θk xk ∈ C. (The definition of convexity is that this holds for k = 2; you must show it for arbitrary k.) Hint. Use induction on k. Solution. This is readily shown by induction from the definition of convex set. We illustrate the idea for k = 3‚ leaving the

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell
