Streak Plate Isolation for Obtaining Pure Cultures Data Interpretation 1- In order to unsure that you get a pure sample. 2-pure culture: laboratory culture containing a single species of organism. A pure culture is usually derived from a mixed culture (containing many species) by methods that separate the individual cells so that‚ when they multiply‚ each will form an individually distinct colony‚ which may then be used to establish new cultures with the assurance that only one type of organism

Observing Protists through Hay Infusion Preparation Abstract: Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now‚ there are many known species of protists. After learning about protists in class‚ the group decided to observe the different species of protists found in pond water. The group prepared a preparation to be able to culture the protists until it was time to view them. After a few days‚ the

Introduction The science of microbiology is all about microorganisms‚ what they do and how they work. Microorganisms are ubiquitous‚ and are a very important part of life everywhere since they have been around for billions of years. The two main themes associated with microbiology are (1) having an understanding of the nature and function of the microbial world‚ and (2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6).

SIGNIFICANCE OF THE STUDY Lagundi is a shrub that can be easily found and grown in the Philippines. It is said to be and effective and proven herbal medicine that has a reparative value. This plant is often used to treat clods‚ flu‚ asthma‚ bronchitis and pharyngitis. Most parts of the lagundi plant have medicinal value. This experiment will be able to lessen the use of chemicals in the body with curing all kinds of sicknesses in a natural way. In our time now‚ the common sicknesses we experience

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

This resembled a culture and sensitivity test that is preformed at the hospital’s laboratory to find out the resistance of a microorganism. This experiment was meant to use the naked eye and a magnifying glass when necessary. Procedures: This experiment called for prepared agar in a petri dish‚ smeared s. epidermis on the surface of the prepared agar‚ and a 3 separate quadrants labeled

The Immune System is a very complicated thing‚ and you can simplify it by comparing it to a defense in football. In football‚ you have three lines of defense‚ just like the Immune System. There is the defensive line‚ linebackers‚ and the secondary. The defensive line is like the first layer of defense‚ the linebackers the second line of defense‚ and the defensive backs the third line of defense. Each of them have their own responsibilities‚ but work together for the same goal. They work as a team
