1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a sample of different

Yannelly De Leon General Intent vs. Specific Intent “Intent: A determination to perform a particular act or to act in a particular manner for a specific reason; an aim or design; a resolution to use a certain means to reach an end.” [1] The difference between General Intent vs. Specific Intent is when the defendant commits a crime with a specific end in mind and general intent is when a defendant commits a crime with no specific result in mind. General intent crime includes but is not limited

Are viruses alive? Explain why you think viruses are alive or not. Viruses are not alive. This is because even though viruses are made up of molecules (proteins‚ nucleic acids‚ carbohydrates and lipids)‚ they cannot do anything on their own‚ until they enter or come into contact with a living cell. Viruses cannot multiply without having a host cell to initiate the process. Another reason would be that viruses don’t actually do anything on their own. Whenever a virus comes into contact with a cell

Penicillin Changed the World Imagine life without antibiotics‚ people dying of a whooping cough‚ a minor wound or even a simple infection. Until the accidental discovery of penicillin by Alexander Flemming‚ life was like this. The positive effects for the discovery of penicillin were the many medical advancements made both therapeutically and medicinally. Economically‚ people were living longer lives and populations were growing more rapidly. Socially‚ people were able to interact without risking

Introduction There are both virulent and non-virulent bacteria and fungi that grow on plants. It is difficult to distinguish between the two without proper inspection and diagnosis of the diseased plant to know whether the bacteria or the fungus in question is the virulent or non-virulent one. Therefore pure cultures need to be isolated to know with absolute certainty which is the causative bacteria or fungus. Potato dextrose agar is a good nutrient agar for mycelia to thrive on which is present

between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are by and large dark

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are

were measured and recorded. A hypothesis that was formulated before experimenting was‚ “If the type of disinfectant is Mouthwash‚ then it will allow for the least amount of bacteria growth because the chemicals present in Mouthwash combined with the acidic environment it bring will make it very hard to allow for any bacteria growth”. The independent variable in this experiment was undeniably
