hypothesis Outline your biological knowledge or research related to the problem under investigation Yeast are eukaryotic species and make up approximately one percent of species in the kingdom Fungi. One of the most well studied yeast species‚ Saccharomyces cerevisiae‚ commonly known as bakers yeast‚ and also used in the fermentation of alcohols‚ is a model species for the study of eukaryotic cells. They are known to reproduce either sexually‚ by mitosis‚ or asexually‚ by budding‚ depending on environmental

Description of Probiotics Probiotics are living microscopic organisms‚ or microorganisms‚ that scientific research has shown to benefit the health. Most often they are bacteria‚ but they may also be other organisms such as yeasts. In some cases they are similar‚ or the same‚ as the “good” bacteria already in the body‚ particularly those in the gut. These good bacteria are part of the trillions of microorganisms that inhabit the bodies. This community of microorganisms is called the microbiota.

INTRODUCTION: Molecular biology began more than 40 years ago with Watson and Crick‘s discovery of the double helix structure of deoxyribonucleic acid DNA and that continued with Cohen and Boyer’s. This discovery of the techniques that called as biotechnology nowadays has had an enormous impact on the nature of research and development. This technique has potential to generate great benefits in improved of human life by through of many applications which play role in improvements of medicine‚ agriculture

Live in both fresh water and marine habitats. Some are found in soil‚ and many have adapted to parasitic life on the body of marine animals or internal organs of both aquatic and terrestrial animals. Amoeba reproduces asexually by binary and multiple fissions. They eat algae‚ bacteria‚ other

The high lymphocyte content of the thymus gland‚ makes DNA extraction much more efficient‚ convenient and productive. In contrast‚ RNA extraction is done for cells that have a high cytoplasmic to nuclear mass ratio‚ such as the fungus Saccharomyces cerevisiae (commonly known as baker¡¦s yeast) used in this experiment. The extraction procedures for both DNA and RNA basically outline the same steps: release of cell contents (through cell membrane lysis)‚ separation of contaminants (lipids‚ proteins

protein folding and stabilization. This also enables it to function in biofilm production. Besides‚ Pseudomonas putida acts as an agent for plant growth and plant pest control. The complex interaction between Pseudomonas putida and Saccaromyces cerevisiae together regulate plant health. It is a mutualism between the prokaryotes and the plant. This is because prokaryotes produce sideospores such as pyoverdine and pyochelin to protect the plant from fungal

Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins
