which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial species from various environmental sources is important in all branches of microbiology since bacteria are ubiquitous and live in microbial communities of mixed populations. Populations in microbial communities or ecosystems may interact and cooperate in their efforts to obtain nutrients from the environment with the waste products

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

Exercise 8-B Differential Staining Gram Staining and Acid Fast Staining Introduction: Differential Staining‚ one which facilitates differentiation of various elements in a specimen is a general term that can refer to a number of specific processes. Using multiple stains can better differentiate between different microorganisms or cellular components of a single organism. Gram’s Stain is a widely used method of staining bacteria as an aid to their identification. It was originally devised by Hans

order to thrive. In the lab‚ we use a Biological Media to aid in growth reproduction. Also referred to as a culture medium‚ a Biological Media is a substance used to support the growth of microorganisms. The two types of media most commonly used in Microbiology are selective media and differential media. Selective media are used to encourage the growth of specific or desired microbes. Differential media on the other hand are used to distinguish colonies of microbes as well as identify different bacteria

However‚ because new strains continue to emerge‚ it is of the utmost importance that microbiologists and microbiology students understand the nature of each bacterial species and how that species creates and maintains its complex communities.
