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 In this experiment‚ I measured the impact of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the

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

For example‚ scratches or cracks in the handle of a food-contact knife creates a great niche for microbial growth and contamination. Eventually‚ the microorganisms are going to slough out onto your product. Tools should be

common types of diseases. However‚ some of the diseases started to build up a resistance to the antibiotics and in result‚ the antibiotics became ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers developed numerous methods to cultivate uncultured organisms

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
