Witnessing the breathtaking phenomena created by marine microbes strengthened my determination to further pursue my study of marine microbiology. In my first year as an undergraduate student I participated in lab work on marine microbiology. I led one project on separation and identification of pigment-containing bacteria in the Xiamen Coastal Areas‚

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

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

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
